SAFETY
AVOID ACCIDENTS
Most accidents, whether they occur in industry, on the farm, at home, or on the
highway, are caused by the failure of some individual to follow simple and
fundamental safety rules or precautions. For this reason, most accidents can be
prevented by recognizing the real cause and doing something about it before the
accident occurs.
Regardless of the care used in the design and construction of any type of
equipment, there are many conditions that cannot be completely safeguarded
against without interfering with reasonable accessibility and efficient operation.
A CAREFUL OPERATOR IS THE BEST INSURANCE AGAINST AN
ACCIDENT. THE COMPLETE OBSERVANCE OF ONE SIMPLE RULE
WOULD PREVENT MANY THOUSAND SERIOUS INJURIES EACH
YEAR. THAT RULE IS:
NEVER ATTEMPT TO CLEAN, OIL OR ADJUST
A
MACHINE WHILE IT IS IN MOTION.
NATIONAL SAFETY COUNCIL
If spreader is used to transport chemicals, check with your chemical supplier
regarding DOT (Department of Transportation) requirements.

SAFETY DECALS
MAINTENANCE INSTRUCTIONS
1. Keep safety decals and signs clean and legible at all times.
2. Replace safety decals and signs that are missing or have become illegible.
3. Replaced parts that displayed a safety sign should also display the current sign.
4. Safety decals or signs are available from your dealer's Parts Department or our Cedar Rapids factory.
INSTALLATION INSTRUCTIONS
1. Clean Surface
Wash the installation surface with a synthetic, free-rinsing detergent. Avoid washing the surface with a
soap containing creams or lotion. Allow to dry.
2. Position Safety Decal
Decide on the exact position before application. Application marks may be made on the top or side edge
of the substrate with a lead pencil, marking pen, or small pieces of masking tape. NOTE: Do not use
chalk line, china marker, or grease pencil. Safety decals will not adhere to these.
3. Remove the Liner
A small bend at the corner or edge will cause the liner to separate from the decal. Pull the liner away in a
continuous motion at a 180-degree angle. If the liner is scored, bend at score and remove.
4. Apply Safety Decal
a. Tack decal in place with thumb pressure in upper corners.
b. Using firm initial squeegee pressure, begin at the center of the decal and work outward in all directions
with overlapping strokes. NOTE: Keep squeegee blade even—nicked edges will leave application
bubbles.
c. Pull up tack points before squeegeeing over them to avoid wrinkles.
5. Remove Pre-mask
If safety decal has a pre-mask cover remove it at this time by pulling it away from the decal at a 180
degree angle. NOTE: It is important that the pre-mask covering is removed before the decal is exposed
to sunlight to avoid the pre-mask from permanently adhering to the decal.
6. Remove Air Pockets
Inspect the decal in the flat areas for bubbles. To eliminate the bubbles, puncture the decal at one end of
the bubble with a pin (never a razor blade) and press out entrapped air with thumb moving toward the
puncture.
7. Re-Squeegee All Edges.

GENERAL SAFETY RULES
Maintenance Section
1. Maintenance includes all lubrication, inspection,
adjustments (other than operational control
adjustments such as feedgate openings, conveyor
speed, etc.) part replacement, repairs and such
upkeep tasks as cleaning and painting.
2. When performing any maintenance work, wear
proper protective equipment—always wear eye
protection—safety shoes can help save your
toes—gloves will help protect your hands against
cuts, bruises, abrasions and from minor burns—a
hard hat is better than a sore head!
3. Use proper tools for the job required. Use of
improper tools (such as a screwdriver instead of a
pry bar, a pair of pliers instead of a wrench, a
wrench instead of a hammer) not only can damage
the equipment being worked on, but can lead to
serious injuries. USE THE PROPER TOOLS.
4. Before attempting any maintenance work (including
lubrication), shut off power completely. DO NOT
WORK ON RUNNING MACHINERY!
5. When guards and covers are removed for any
maintenance, be sure that such guards are
reinstalled before unit is put back into operation.
6. Check all screws, bolts and nuts for proper
torques before placing equipment back in service.
Refer to torque chart in this manual.
7. Some parts and assemblies are quite heavy.
Before attempting to unfasten any heavy part or
assembly, arrange to support it by means of a
hoist, by blocking or by use of an adequate
arrangement to prevent it from falling, tipping,
swinging or moving in any manner which may
damage it or injure someone. Always use lifting
device that is properly rated to lift the equipment.
Do not lift loaded spreader. NEVER LIFT
EQUIPMENT OVER PEOPLE.

GENERAL SAFETY RULES
Maintenance Section
8. If repairs require use of a torch or electric welder, be
sure that all flammable and combustible materials are
removed. Fuel or oil reservoirs must be emptied, steam
cleaned and filled with water before attempting to cut or
weld them. DO NOT weld or flame cut on any tank
containing oil, gasoline or their fumes or other
flammable material, or any container whose contents or
previous contents are unknown.
9. Keep a fully charged fire extinguisher readily available
at all times. It should be a Type ABC or a Type BC
unit.
10. Cleaning solvents should be used with care. Petroleum
based solvents are flammable and present a fire hazard.
Don’t use gasoline. All solvents must be used with
adequate ventilation, as their vapors should not be
inhaled.
11. When batteries are being charged or discharged, they
generate hydrogen and oxygen gases. This combination
of gases is highly explosive. DO NOT SMOKE
around batteries—STAY AWAY FROM FLAME—
don’t check batteries by shorting terminals as the spark
could cause an explosion. Connect and disconnect
battery charger leads only when charger is “off”. Be
very careful with “jumper” cables.
12. Batteries contain strong sulfuric acid—handle with care.
If acid gets on you, flush it off with large amounts of
water. If it gets in your eyes, flush it out with plenty of
water immediately and get medical help.
13. Hydraulic fluid under high pressure leaking from a pin
hole are dangerous as they can penetrate the skin as
though injected with a hypodermic needle. Such liquids
have a poisonous effect and can cause serious wounds.
Get medical assistance if such a wound occurs. To
check for such leaks, use a piece of cardboard or
wood instead of your hand. The fine spray from a small
hydraulic oil leak can be highly explosive—DO NOT
SMOKE—STAY AWAY FROM FLAME OR
SPARKS.

HIGHWAY EQUIPMENT COMPANY
GENERAL SAFETY RULES
Installation Section
1. The selection of the vehicle on which a
spreader body is to be mounted has
important safety aspects.
overloading:
To avoid
a. Do not mount spreader on a chassis
which, when fully loaded with material
to be spread, will exceed either the
Gross Axle Weight Rating (GAWR)
or the Gross Vehicle Weight Rating
(GVWR) for the chassis.
b. Do install the spreader only on a
vehicle with cab-to-axle dimension
recommended for the spreader body
length shown.
2. Follow mounting instructions in the
Installation section of this manual. If
mounting conditions require deviation
from these instructions refer to factory.
3. When making the installation, be sure that the lighting meets Federal Motor Vehicle Safety Standard
(FMVSS) No. 108 and all applicable local and state regulations.
4. When selecting a PTO to drive hydraulic pump, do not use a higher percent speed drive than the Truck-
PTO-Pump Match Graph indicates in the Installation section of this manual. Too high a percent PTO will
drive pump at excessive speed, which can ruin the pump, but more importantly, will overheat the hydraulic
oil system and increase the possibility of fire.
5. When truck frame must be shortened, cut off only the portion
that extends behind rear shackle in accordance with the truck
manufacturer’s recommendations. If a torch is used to make
the cut, all necessary precautions should be taken to prevent
fire. Cuts should not be made near fuel tanks and hydraulic oil
reservoirs, fuel, brake, electric or hydraulic lines and such lines
should be protected from flame, sparks or molten metal. Tires
should be removed if there is any chance of their being struck
by flame, sparks or molten metal. Have a fire extinguisher
handy.

GENERAL SAFETY RULES
Installation Section
5. Do not weld on vehicle
frame as such welding can
lead to fatigue cracking and
must be avoided. When
drilling holes in frame
member, drill only through
the vertical web portions-
do not put holes in top or
bottom flanges. Refer to
truck
manufacturer’s
recommendations.
6. Be sure that welds between mounting bars and sill or between mounting angles and spreader cross sills are
sound, full fillet welds. Center mounting angles so that good fillet welds can be made on three sides—and
edge bead weld is not a satisfactory weld for this service. Use dry, E6013 or E7018 rod for normal
steels. On stainless steel bodies use SAE grade 5 bolts—welding is recommended if type 308 welding
rod is available.
7. Install controls so that they are located of convenient use. Position them so that they do not interfere with
any vehicle control and that they do not interfere with driver or passenger or with access to or exit from
the vehicle.
8. Check for vehicle visibility, especially toward the rear. Reposition or add mirrors so that adequate
rearward visibility is maintained.
9. Add Caution, Warning, Danger and Instruction decals as required. Peel off any label masking which has
not been removed.
10. Install all guards as required.
11. Check installation completely to be sure all fasteners are secure and that nothing has been left undone.

GENERAL DESCRIPTION
The Model L2020G4 is a hopper-type spreader intended for spreading free-flowing granular agricultural
materials, such as chemical fertilizers, agricultural limestone and gypsum. It is intended for truck chassis or
flotation vehicle mounting. It also may be incorporated into a towed trailer unit.
The unit is powered hydraulically and provides independent variable speed control for the spinner. The
conveyor has full automatic ground speed coordinated control by means of a motorized valve with shaft sensor
or Mark series control system. The hydraulic pump, which provides the hydraulic power, is a gear-type pump
that is driven by means of a transmission PTO.
The conveyor runs the full length of the hopper bottom to deliver material to the spinners through an adjustable
metering gate at the rear of the hopper body. It is driven by an orbital type hydraulic motor integrally mounted
to a 6 to 1 ratio spur gear box. The standard conveyor is a number five straight belt on ten foot through
thirteen foot units and a number four Belt-over-chain on fourteen foot through sixteen foot units.
The distributor spinner assembly has two 24 inch diameter dished discs. Each disc has four formed and heat
treated fins. Each fin’s angle can be adjusted. The spinner is fully adjustable by means of a rotating handle.
This product is intended for commercial use only.

INSTALLATION INSTRUCTIONS
Recommended sequence of installation is:
1. Mounting of PTO and pump drive.
2. Installation of radar (if applicable)
3. Mounting of spreader.
4. Installation of controller and encoder (if applicable)
5. Installation of hydraulic hose and electrical wiring.
6. Installation of optional parts.
7. Filling of hydraulic tanks and lubrication.
8. Checking for leaks and proper functioning.
Pump and truck requirements must be determined prior to installation of the
L2020G4.
IMPORTANT!
PUMP AND PTO REQUIREMENTS:
Hydraulic Requirements
Maximum Pressure: 3100 PSI
Flow:
30-34 GPM (Gallons per Minute)
Sizing Data Required:
Since the amount of material per acre to be spread depends upon the match between pump size, pump speed
(which depends upon engine speed and PTO percent), conveyor delivery rate and feedgate opening, it is
essential that a correct match between these factors be made. This matching is called “sizing.”
1. Correct sizing requires accurate and complete information.
A. Engine governed operating speed.
B. Transmission make and model.
C. PTO Data
1. Make and model of PTO.
2. PTO percentage of engine RPM.
3. Direction of PTO Rotation (Engine direction or opposite of engine direction).
Excessive engine speed will cause more hydraulic oil to be pumped than is required to
drive spinners and conveyor and may result in overheating the oil. Too low an engine
speed may not provide sufficient hydraulic oil flow to maintain spread width or to
keep the conveyor running at the speed required to deliver the desired quantity of

Do not select a PTO % and an engine RPM resulting in more than 3000 PTO RPM.
Driving the pumps (referenced above) at speeds greater than 3000 RPM will result in
premature failure of the pump and other hydraulic components.
IMPORTANT!
TRUCK REQUIREMENTS
In mounting the L2020G4 spreader on a truck, the following questions must be considered:
1. Is the CA/CT (Cab to Axle/Cab to Tandem) dimension of the truck correct for the length of the
spreader?
See the Dimensions charts on page 20. This will assist in matching spreader to truck.
2. Is the truck’s GAWR (Gross Axle Weight Rating) and the GVWR (Gross Vehicle Weight Rating)
adequate to carry the fully loaded spreader?
Refer to your New Leader dealer. He knows where to find the GAWR and GVWR for most
trucks, and how to calculate the weight distribution on each axle and total loaded vehicle weight.

HYDRAULIC PUMP INSTALLATION
A mounting bracket for the hydraulic pump is shipped with the spreader. It may be necessary to modify this
bracket to fit your truck since many variable factors such as PTO make and model, muffler position,
transmission make and model, etc., all affect the mounting position. DO NOT WELD THE BRACKET TO
THE TRUCK FRAME. To do so may void the truck manufacturer’s warranty.
Position the mounting bracket so that the pump drive shaft will be as straight possible. In no case should the
angle of any universal joint exceed 15º. The pump shaft and PTO shaft should be parallel. (Figure 1)
HYDRAULIC PUMP DRIVE SHAFT INSTALLATION
The pump drive shaft included may be too long for some installations. It may be cut and redrilled as
necessary. When redrilling the shaft, be sure that universal joints are properly “timed”, as shown in Figure 1.
Install the slip joint at the end of the pump drive shaft. Failure to install the slip joint will result in bearing failure
in pump, PTO or both.

Truck Frame Length
The length from the rear of the cab to the rear end of the frame should be approximately as shown on
“Dimensions and Capacities” chart under “C”. Shorten truck frame as necessary, making sure to follow truck
manufacturer’s specifications so as not to void truck warranty.
Filler Strips
Do not weld to truck frame; it may void truck warranty.
IMPORTANT!
A level top surface is necessary for mounting. Add steel shim bars or strips the same thickness as fish plates
or other obstructions and as wide as the truck frame channel top flange. Shims must be drilled to clear any
rivet or bolt heads.
Units with rubber mounting pads do not require wood filler strips—continue to Positioning Body on next
page. Rubber mounting pads may be ordered or follow instructions below if not so equipped.
Hardwood filler strips (not supplied) 1” by 3” must be installed the full length of the truck frame. Cut filler
strips to length and place on truck frame rails. If frame has rivets in top flange, mark position of rivets on filler
strips, remove and counterbore for rivet head clearance. Secure filler strips and steel shims (if applicable) to
frame top flange by bending anchor clips around them as shown in Figure 2. Attach three anchor clips per
steel shim and per wood filler strip. Locate anchor clips between spreader body cross tubes. Attach anchor
clips by driving a 1/4” sheet metal screw through clip into wood filler strip as shown in Figure 2.

LUBRICATION & MAINTENANCE
PREVENTATIVE MAINTENANCE PAYS!
The handling and spreading of commercial fertilizers is a most severe operation with respect to metal
corrosion. Unless a frequent, periodic preventative maintenance program is established, rapid damage to
spreading equipment can occur. Proper cleaning, lubrication and maintenance will give you longer life, more
satisfactory service and more economical use of your equipment.
Shut off all power and allow all moving parts to come to rest before
performing any maintenance operation.
WARNING
HYDRAULIC SYSTEM
Proper oil in the hydraulic system is one of the most important factors for satisfactory operation. Utmost
cleanliness in handling the oil cannot be stressed enough. Keep hydraulic oil in original closed containers,
clean top of container before opening and pouring, and handle in extremely clean measures and funnels.
Refer to “Lubricant and Hydraulic Oil Specifications” section of the manual for selection of the proper
hydraulic fluid for use in the hydraulic system.
Service Schedule
1. Check hydraulic oil daily by means of sight gauge on reservoir. Add oil if required. Periodically inspect
hoses and fittings for leaks.
DO NOT check leaks with hands while system is operating as high pressure
WARNING
leaks are very dangerous! DO NOT check for leaks adjacent to moving parts
while system is operating as there may be danger of entanglement!
2. Change hydraulic oil filter after first week (or not more than 50 hours) of operation on a unit.
3. After first filter change, replace filter when indicator reaches Red Zone.
4. Drain reservoir through drain plug (not through suction outlet), flush, and refill and change filter element
annually. Oil and filter should also be changed whenever oil shows any signs of breaking down under
continued high-pressure operation. Discoloration of oil is one sign of breakdown.

HYDRAULIC HOSE
Hose assemblies in operation should be inspected frequently for leakage, kinking, abrasion, corrosion or any
other signs of wear or damage. Worn or damaged hose assemblies should be replaced immediately.
Clean
Clean assembly by blowing out with clean compressed air.
Assemblies may be rinsed out with mineral spirits if the tube
stock is compatible with oil, otherwise hot water at 150 degrees
F maximum may be used.
Inspect
Examine hose assembly internally for cut or bulged tube,
obstructions, and cleanliness. For segment style fittings, be sure
that the hose butts up against the nipple shoulder; band and
retaining ring are properly set and tight, and segments are
properly spaced. Check for proper gap between nut and
socket or hex and socket. Nuts should swivel freely. Check the
layline of the hose to be sure the assembly is not twisted. Cap
the ends of the hose with plastic covers to keep clean.
Test
The hose assembly should be hydrostatically tested at twice the
recommended working pressure of the hose.
Test pressure should be held for not more than one minute and
not less than 30 seconds. When test pressure is reached,
visually inspect hose assembly for: 1. Any leaks or signs of
weakness. 2. Any movement of the hose fitting in relation to the
hose. Any of these defects are cause for rejection.
Testing should be conducted in approved test stands with adequate guards to
protect the operator.

CONVEYOR CHAIN
Hose down unit and remove any material build-up on sprockets and under chain.
The conveyor will move away from the bottom panel if material accumulates
under the conveyor or on the sprockets. The more material that accumulates,
the closer the chain will come to the chain shields. If the conveyor should catch
a chain shield, it could permanently damage the conveyor, the chain shields or
the unit. Do not remove material while conveyor or spinner is running!
IMPORTANT!
Lubricate conveyor chain daily. Shut down spinner and run conveyor slowly to lubricate chain. Use a
mixture of 75% fuel oil and 25% SAE 10 oil in a pressurized hand spray gun. Spray oil mixture
between links of chain through openings provided at rear end of sill or from front outside body when
clearance is adequate. After each unit washing, allow to dry, then lubricate.

Adjustment
1. TENSION
Belt tension should be just tight enough to prevent slippage—no tighter. If the “flats” on
the conveyor drive pulley are visible through the belt, tension is high enough.
2. TRACKING
Empty spreader to check tracking by doing the following:
A. Make sure truck engine is shut off and move spinner control valve to “0” position. Start
truck engine and engage pump drive PTO. Spinners should not turn. If they do, correct
the problem before proceeding.
Do not work near rotating spinners. Severe injury can result from contact
with moving parts.
WARNING
B. Run truck engine, place controller in manual mode (see control manufacturer’s manual)
and run conveyor at slow speed. Gradually increase speed until tracking is visual.
Use great care to avoid entanglement with any moving parts.
CAUTION
A properly adjusted belt will either remain in a steady position centered on the pulley or more often
will “wander” back and forth 1/4 to 1/2 inch across the pulley, but remain generally centered. The
conveyor belt sides should not curl or scuff.
Improper tracking is usually due to three basic causes. These problems and their respective solutions
follow:
PROBLEM 1: (Figure 11)
Belt tracks to one side, contacts side of conveyor. Contact is more severe at the front and may not
quite touch at the rear.
SOLUTION:
Tighten idler bearing at side in contact with belt. Make this adjustment one turn at a time. Operate
conveyor 10 to 15 minutes at a high speed to allow belt to react to the adjustment. Repeat if necessary.

PROBLEM 2: (Figure 12)
Belt contacts one side at front and contacts other side at rear.
SOLUTION:
If adjusting as in Problem 1 does not remedy the situation, adjustment of the drive pulley is necessary.
Mark the position of the adjustment screw (RH side) on the side of the unit. Determine which
illustration shows the problem to figure out which direction the drive shaft should be moved. Loosen
the adjustment screw to move the shaft forward; tighten the screw to move the shaft rearward.
NOTE: The illustration is exaggerated. Only move the adjustment screw 1/4 turn at a time after
loosening the bolts holding the bearing. Usually, 1/64 to 1/32 inch adjustment is all that is necessary.
Retighten bearing. Operate conveyor for 10 to 15 minutes at a high speed to allow belt to react to
adjustment. The problem should change to Problem 1. Adjust as in Problem 1 to track belt properly.

PROBLEM 3: (Figure 13)
Belt contacts side as in Problem 1, but contacts more heavily at a point approximately three feet from
rear.
SOLUTION:
Realign snubber pulley. Note the point or side of contact from the illustration. This side of the
snubber is too low. NOTE: This pulley moves up and down ONLY.
Loosen belt and raise or lower as necessary. Loosen the two bolts holding the snubber bearing on the
side to be adjusted after marking the old position. Move approximately 1/16 inch at a time and
retighten. Retighten belt the exact number of turns previously loosened. Operate conveyor 10 to 15
minutes to allow belt to react to adjustment. Refer to Problem 1 and readjust. If readjustment does not
compensate, repeat.

If, after continued adjustment, the belt does not track properly, check the following:
1. Check for twisted spreader body. Shims must be placed between spreader cross tubes and the
mounting surface to eliminate any twist in the body structure.
2. Check for crowned Idler Pulley by placing a straight edge on the pulley. If properly crowned, the
straight edge will contact the center pulley leaving 1/16 inch gap between the straight edge and both
pulley ends. Replace the pulley if crown is not present.
3. Check for lacing squareness by removing the belt. This should be done as a last resort. If the
lacing is not square to the belt ends, contact your dealer for service.
4. Sight down the body under the belt shields. The only point which should come close to or slightly
contact the belt, is the lowest point on the shield. If the belt contacts the shield firmly at any other
point, tracking will be impossible and you should see your dealer immediately. Only your dealer
can correct the situation.
Shield
The belt shields along each side of the belt inside the unit should be just contacting the belt when the
belt is properly adjusted and the unit is empty (Figure 14). If a shield has clearance along its length, it
can be moved down until it just contacts the belt by loosening the fastener bolts, allowing the shield to
slide downward and tightening the bolts. If the shield is tending to cut into the belt along its full
length, loosening the bolts and raising the shield until it just contacts the belt will correct the problem.
If the shield cuts the belt at one or more points or if it gaps at one or more points, it should be replaced.

LUBRICATION OF BEARINGS
Grease in a bearing acts to prevent excessive wear of parts, protects ball races and balls from corrosion and
aids in preventing excessive heat within the bearing. It is very important the grease maintains its proper
consistency during operation. It must not be fluid and it must not channel.
Lubricate bearings by pumping grease slowly until it forms a slight bead around the seals. This bead indicates
adequate lubrication and also provides additional protection against the entrance of dirt.
Make sure all fittings are thoroughly cleaned before grease is injected. Points to be lubricated by means of a
grease gun have standard grease fittings.
CLEAN UP
High pressure wash can inject water and/or fertilizer into control components,
IMPORTANT!
causing damage. Use caution when cleaning these areas.
Thoroughly wash unit every two to three days during the operating season to maintain minimal maintenance
operation. Hose unit down under pressure to free all sticky and frozen material.
It is important the unit be thoroughly cleaned at the end of each operating season. All lubrication and
maintenance instructions should be closely followed. Repaint worn spots to prevent formation of rust.
FASTENERS
Tighten all screw fasteners to recommended torque’s after first week of operation and annually thereafter. If
loose fasteners are found at any time, tighten to the recommended torque. Replace any lost or damaged
fasteners or other parts immediately. Check body mounting hardware every week.
