WARNING! The items listed in this section will help you keep your DR  
LEAF and LAWN VACUUM running smoothly and, most  
importantly, prevent injury to yourself or others. Please  
review them carefully before starting your machine.  
Protecting Yourself  
ꢀ Always wear eye protection while operating either your tractor lawn deck, vacuum

moving parts.  
ꢀ We recommend wearing snug-fitting work gloves while using the system as a chipper.  
Operating the Machine Safely  
ꢀ Inspect the area in which you will be working. The site must be free of potentially  
hazardous obstacles (e.g., stones, glass and metal objects such as cans).  
ꢀ Pile sticks that you intend to chip separately and away from the vacuum site.  
ꢀ Never operate your machine unless all hoses and covers are secured and in good  
condition. Objects can be thrown at high velocity through openings in hoses and the  
Collector Box.  
ꢀ Never allow people who are unfamiliar with these instructions to use the DR LEAF

ꢀ When using the DR LEAF and LAWN VACUUM as a trailer, be sure to secure the  
load.  
ꢀ DO NOT tow the DR LEAF and LAWN VACUUM faster than 8 MPH.  
ꢀ Keep your hands out of the Chipper Hopper and Vacuum Inlet while the lawn tractor  
and the DR LEAF and LAWN VACUUM engines are running. If it becomes  
necessary to push material into the Hopper, use a small diameter stick.  
ꢀ Always shut off the lawn tractor engine and the DR LEAF and LAWN VACUUM  
engine, and disconnect the spark plug wire before attempting to clear any obstructions  
in the hoses or Chipper Hopper.  
ꢀ Remove side branches before chipping to prevent jamming the material in the Chipper  
Hopper.  
ꢀ The exhaust area on the engine becomes very hot with use. Allow the engine to cool  
before doing maintenance or making adjustments.  
ꢀ Keep your hands and combustible substances away from the engine when it is hot and  
clean the engine area after each use.  
ꢀ Use the DR LEAF and LAWN VACUUM only in daylight.  
ꢀ ALWAYS FEED THE CHIPPER FROM THE CHIPPING ZONE (Figure 27).  
Never straddle or reach over the engine area at any time.  
ꢀ Do not attempt to chip wood larger than specified in this manual.  
ꢀ Use only your hands to operate the DR LEAF and LAWN VACUUM engine controls.  
Always dismount your lawn tractor when starting and stopping the DR LEAF and  
LAWN VACUUM engine to prevent contact with the hot muffler.  
ꢀ Never use the DR LEAF and LAWN VACUUM to vacuum anything but yard waste,  
such as leaves, grass, small twigs and pine cones.  
ꢀ If the machine starts to make an unusual noise or vibration, immediately shut off the  
engine, disconnect the spark plug wire, and allow all moving parts to come to a  
complete stop. Inspect for clogging or damage. Clean and repair and/or replace  
damaged parts.  
ꢀ Do not, under any conditions, remove, bend, cut, fit, weld, or otherwise alter standard  
parts on the DR LEAF and LAWN VACUUM. Modifications to your machine could  
cause personal injuries and will void your warranty.  
ꢀ Do not alter or tamper with safety devices or shields. Make sure they are in proper  
position.  
ꢀ Only use accessories approved for this machine by Country Home Products. Read,  
understand, and follow all the instructions provided with the approved accessory.  
ꢀ While using the DR LEAF and LAWN VACUUM, don't hurry or take things for  
granted.  
ꢀ Never leave the DR LEAF and LAWN VACUUM unattended with its motor running.

Slope Operation  
Slopes are a major factor related to tip over accidents, which can result in severe injury. All  
slopes require caution. If you feel uneasy on a slope, do not vacuum it.  
DO:  
ꢀ Vacuum up and down the face of slopes; never across. Exercise extreme caution when  
changing direction on slopes.  
ꢀ Remove objects such as stones, glass and metal objects such as cans.  
ꢀ Watch for holes, ruts, or bumps. Tall grass can hide obstacles.  
DO NOT:  
ꢀ Do not operate on slopes greater than 20 degrees.  
ꢀ Do not vacuum near drop-offs, ditches, or embankments. Your tractor and the vacuum  
may tip over.  
ꢀ Do not vacuum excessively steep slopes.  
ꢀ Do not vacuum on wet slopes. Reduced traction could result in slipping and a possible  
roll over.  
Safety for Children  
Tragic accidents can occur if the operator is not alert to the presence of children. Children  
are often attracted to the tractor and the vacuuming/chipping activity. Never assume that  
children will remain where you last saw them.  
ꢀ Keep children out of the work area and under the watchful care of a responsible adult.  
ꢀ Be alert and always shut OFF the lawn tractor engine and the DR LEAF and LAWN  
VACUUM engine if children enter the work area.  
ꢀ Before and while moving backwards, look behind and down for small children. You  
cannot see directly behind the Collector Box.  
ꢀ Never allow children to operate the tractor or vacuum.  
ꢀ Never allow children to play in the Collector Box. If they become trapped in the  
enclosure they may be exposed to temperatures similar to leaving a child in a car with  
the windows closed on a sunny day.  
ꢀ Use extra care when approaching blind corners, shrubs, trees, or other objects that may  
obscure your vision.

Safety with Gasoline-Powered Machines  
ꢀ Do not run the engine in an enclosed area or without proper ventilation.  
ꢀ Store all fuel in containers specifically designed for this purpose.  
ꢀ Fill the gasoline tank outdoors with the engine off. Allow the engine to cool at least  
two minutes before refueling. Don't handle gasoline if you or anyone nearby is  
smoking, or if you are near anything that could cause the gasoline to ignite or explode.  
ꢀ If you spill gasoline, do not attempt to start the engine. Replace the gasoline cap  
securely, move the machine away from the area of the spill and avoid creating any  
source of ignition until the gas vapors have dissipated. Wipe up any spilled fuel to  
prevent a fire hazard and properly dispose of the waste.  
ꢀ Allow the engine to cool completely and empty the Collector Box before storing the  
DR LEAF and LAWN VACUUM in any enclosure. Remember, decomposing material  
can generate heat and start a fire. Never store the machine near an open flame or spark  
with gasoline in the tank.  
ꢀ Do not change the engine governor settings or modify the engine speed. Modifications  
will void your warranty.  
ꢀ Do not allow any part of the engine, especially around the cooling fan and muffler, to  
become clogged with leaves, grass, oil, grease or any other combustible material.  
ꢀ Do not operate the engine if the air cleaner or cover over the carburetor air-intake is  
removed, except for adjustment. Removal of such parts could create a fire hazard.  
Note: If situations occur that are not covered by this manual, use care and good judgment.  
Call 1(800) DR-OWNER (376-9637) for assistance.  
A Note to All Users  
Under California law, and the laws of some other states, you are not permitted to operate  
an internal combustion engine using hydrocarbon fuels without an engine spark arrester.  
This also applies to operation on US Forest Lands. All DR LEAF and LAWN VACUUMS  
shipped to California and Washington State are provided with spark arresters. Failure of  
the owner or operator to maintain this equipment in compliance with state regulations is a  
misdemeanor under California law and may be in violation of other state and/or federal  
regulations. Contact your local fire marshal or forest service for specific information in  
your area.

3. To assure that the hose has the  
proper length, turn the tractor  
all the way to the left, while  
watching the hose. The hose  
should not become too taut so  
as to move or damage your  
lawn deck adapter. If the trailer  
tongue is able to contact the  
Hitch Plate, without stressing  
the hose or lawn deck adapter,  
the hose is of sufficient length  
(Figure 23).

4. Attach the hose support  
lanyard loosely, with the  
supplied white plastic cable tie,  
in the center of the vacuum  
hose.  
5. To assure that the hose will not  
drag on the ground, turn the  
tractor to the right while  
watching the hose. If the  
supplied hose support lanyard  
is not sufficient to prevent the  
hose from kinking or dragging  
on the ground, reduce the  
length of the hose by removing  
the hose clamp with a screw  
driver at the inlet of the blower  
and cutting the hose to length  
required using wire cutters to  
cut the spiral and then cut the  
hose with the razor knife. If  
the trailer tongue is able to  
contact the hitch plate, without  
allowing the hose to kink or  
drag on the ground, the hose  
has sufficient support (Figure 23).  
Max right turn  
Figure 23

Towing Safety  
ꢀ Never allow anyone to ride in or on the DR LEAF and LAWN VACUUM.  
ꢀ Obey local, state, and federal regulations when you tow the DR LEAF and LAWN  
VACUUM across public roads and highways.  
ꢀ Use caution when backing up your lawn tractor or trying to make tight turns going  
forward with the DR LEAF and LAWN VACUUM attached. The trailer hitch has an  
anti-jackknifing feature, which limits the turning radius. Trying to turn too sharply can  
cause damage to the trailer hitch and/or the lawn tractor if you hit an obstacle. Go  
slowly in areas where tight turns are necessary. Straighten out the system before  
attempting to back up.  
WARNING! Watch out for low branches, overhangs and guy wires that may  
catch on top of the Collector Box.  
Important! The DR LEAF and LAWN VACUUM trailer is not equipped for highway  
use.

Slopes & Uneven Terrain  
WARNING! Never operate your machine on slopes greater than 20 degrees.  
When operating the DR LEAF and LAWN VACUUM over  
uneven terrain and slopes, use EXTREME CAUTION to not tip  
over the machine. Move slowly, especially with a full load, if the  
ground has ruts, bumps and other depressions.  
ꢀ Do not use the DR LEAF and  
LAWN VACUUM on slopes  
greater than 20 degrees.  
Doing so could result in  
serious injury or damage to  
your machine (Figure 30).  
ꢀ On a slope, a heavy load will  
tend to shift. When using your  
DR LEAF and LAWN  
20° MAX  
VACUUM, keep in mind that  
loads tend to shift to the  
downhill side of the Collector  
Box. The higher and heavier  
the load, the greater the  
chance the machine may tip  
over.  
Figure 30  
ꢀ Travel up and down slopes  
(Figure 30) and avoid going  
across slopes. This is the same  
recommendation for mowing  
with your lawn tractor alone.

Operating the Chipper  
In addition to towing the DR LEAF and LAWN VACUUM with your lawn tractor, and  
using it as a vacuum; the system also allows you to chip sticks and limbs up to 2" in  
diameter.  
WARNINGS!  
ꢀ Always operate the chipper from the “Chipping Zone” (see Figure 27 on page 25).  
ꢀ To prevent damage to your chipper, feed only wood up to 2" in diameter into the  
Chipper Hopper.  
ꢀ Before performing any maintenance procedure, stop the engine and disconnect  
the spark plug wire.  
ꢀ NEVER use your hand to push the remaining wood stub down into the Chipper  
Hopper or try to remove a lodged piece of wood with the engine running.  
1. Start the engine in accordance with “Starting & Stopping” on page 24.  
2. To process branches; feed them into the Chipper Hopper opening (Figure 31).  
3. As the chipped branch shortens, finish chipping it by pushing the stub down the  
Hopper with the next branch to be chipped.

Tips:  
ꢀ It is best to trim off any side twigs from the main branch being chipped (Figure 32).  
ꢀ Green branches process quicker and easier than dry branches and soft wood is easier  
than hardwood.  
ꢀ Use caution with small diameter green saplings and branches. Chip these grouped or  
bundled together to provide support for each other (Figure 33).  
ꢀ Make sure the Chipper finishes chipping material in the Hopper before shutting the  
engine off.

Tip: Give the Dump Handle a little shake after emptying the Collector Box to loosen up  
the remaining material. Then drive forward about a foot with the Collector Box in  
the dump position. Shake the handle again and then lower the Tilt Bed back down  
until the Dump Lever locks into place. This usually gets all but a small amount of  
material to dump from the Collector Box. Clean or wipe away the remaining material  
and you are ready to reinstall the Rear Panel.  
Tip: For heavy loads, it may be necessary to manually remove part of the load before  
dumping to reduce the tipping effort.  
Use as a Trailer  
The DR LEAF and LAWN VACUUM may be used as a trailer (500 lbs. MAX) to haul  
firewood, stones, brush, etc., around your property. There are a few options available to  
use your DR LEAF and LAWN VACUUM as a trailer.  
WARNINGS!  
ꢀWhen using the DR LEAF and LAWN VACUUM as a trailer, NEVER  
allow people or animals to ride in or on the trailer.  
ꢀRaise the Support Legs prior to towing this equipment. Extended  
support legs can be damaged or deformed if they hit the ground or an  
object.  
ꢀSecure the load to prevent it from shifting.  
Important! The trailer is not equipped for highway use.  
ꢀ Remove just the Rear Panel (Figure 37)  
or,  
ꢀ Remove just the Front and Rear Panels  
or,  
ꢀ Remove the Front and Rear Panels, and

LEAF and LAWN VACUUM Tips  
Tip: For the most efficient use of the DR LEAF and LAWN VACUUM, use this  
sequence of steps:  
WARNING! Pickup stones, metal objects, glass and sticks before vacuuming.  
1. Gather and pile sticks to be chipped.  
2. Chip the smaller sticks and branches.  
3. Remove the rear panel and load the larger limbs (Figure 37).  
4. Dump the load at the desired location.  
5. Mow and vacuum leaves.  
Tip: Be careful in corners. Practice in first gear to understand the effects of the trailer on  
your ability to turn sharply. Drive your DR LEAF and LAWN VACUUM into the  
corner of your property and back out straight to mow as close to the corner as  
possible. Avoid going thru ditches.  
Tip: Eyebolts have been provided on the sides of the Collector Box so that you can attach  
accessories or other tools to transport them around the work site. Items can be  
attached with ropes or elastic (Bungee) cords provided by the user.  
Tip: The lawn deck will tend to scatter some leaves in front and to the right of the lawn  
deck. Keeping this discharge side toward the remaining leaves will simplify cleanup  
by avoiding blowing leaves back onto the areas that you already finished. When you  
need to vacuum with the discharge side toward the completed area of the lawn, then  
overlap the discharge side of the lawn deck at least a foot over the already completed  
section of the lawn.  
Tip: To prevent clogging the lawn deck adapter and vacuum hose, mow grass that is dry  
and not more 2" at a time. Cutting less than 1/3 the grass height is recommended to  
keep your grass healthy.  
Tip: Run your lawn deck with your tractor at full throttle all the time to maximize the lift  
from your lawn deck and assist your DR LEAF and LAWN VACUUM system.  
Tip: Avoid dragging the Inlet Hose over curbs, stonewalls or piles of cut branches. The  
hose is tough, but can puncture on sharp objects. This could also crack the Blower  
Inlet Adapter.

Removing the Blower/Chipper Engine Unit  
WARNINGS!  
ꢀ Before performing any maintenance procedure, stop the engine and  
disconnect the spark plug wire.  
ꢀ Before performing this procedure, assure that your DR LEAF and LAWN  
VACUUM is on level terrain and the brake is set on your lawn tractor.  
ꢀ Do not use Chipper or Vacuum features without first securing the engine to  
the frame and securing the hoses.  
1. Disconnect the Blower Exit Elbow Assembly from the Collector Box Hose  
(Figure 44).  
2. Lower the three (3) frame support legs by removing the Safety Hitch Pins  
(Figure 18 on page 18). When the legs are lowered, re-insert the pins and attach  
the clips.  
3. Remove the Hitch Clip from the Clevis Pin and remove the pin (Figure 19 on  
page 18). Move the trailer tongue from the tractor hitch plate in a side motion.  
4. Remove (turn counterclockwise) the two Rear Retaining Knobs holding the  
engine plate to the trailer frame (Figure 47).  
5. Hold the trailer tongue and remove the two Front Retaining Knobs (Figure 47),  
thus preventing the trailer from falling when the last knob is removed.  
6. Slowly lower the trailer from under the engine (Figure 48). The engine assembly  
is now free to be moved away from the trailer.  
7. Carefully roll the Engine Assembly forward from the trailer frame (Figure 48).  
8. Store the engine assembly in a dry location.  
9. Reverse this procedure to re-install the engine unit then refer to page 18,  
“Connecting the DR LEAF and LAWN VACUUM to your lawn tractor”.  
10. Check the Safety Interlock Switch. See page 16.

End of Season & Storage  
WARNING! Before performing any maintenance procedure, stop the  
engine and disconnect the spark plug wire.  
Note: Please refer to the engine owner manual for engine-specific procedures.  
ꢀ Change the oil.  
ꢀ If your DR LEAF and LAWN VACUUM will be idle for more than 30 days, we  
recommend using a gas stabilizer. This will prevent sediment from gumming up the  
carburetor. If there is dirt or moisture in the gas or tank, remove it by draining the  
tank. Completely fill the tank with fresh, unleaded gas and add the appropriate  
amount of stabilizer or gasoline additive. Run the engine for a short time to allow  
the additive to circulate.  
ꢀ Remove the spark plug and pour about 1 ounce of motor oil into the cylinder hole.  
Replace the plug and pull the recoil starter rope until you feel strong resistance.  
This will coat the piston and seat the valves to prevent moisture buildup.  
ꢀ Clean/replace the air filter.  
ꢀ Clean dirt and debris from the cylinder head cooling fins, blower housing, debris  
screen and muffler area of the engine.  
ꢀ Clean out residual debris from the blower hoses and Collector Box.  
ꢀ If the DR LEAF and LAWN VACUUM will be used as a trailer during the end of  
season, we recommend that you remove and store the engine in a dry location. See  
page 40.  
ꢀ For minimal storage space, you can disassemble the Collector Box by removing the  
Rear & Front Panels, Centrifugal Separator (Top), and the Side Panels. The  
Collector Box pieces then can be stacked against a wall in a convenient location. See  
page 14 for disassembly and re-assembly of the Collector Box.

Daily Checklist for the DR LEAF and LAWN VACUUM  
To help maintain your DR LEAF and LAWN VACUUM for optimum performance, we  
recommend you follow this checklist each time you use your machine.  
[ ]OIL: With the machine on a level surface, remove the oil fill cap and check the oil level.  
Fill the reservoir according to the dipstick with SAE 30 HD motor oil. (See page 23)  
[ ] GAS: Fill the gas tank with fresh, unleaded gasoline. See page 23.  
[ ] ENGINE: It is very important to keep the engine clean. Remove dirt and other debris from  
the engine cooling fins and debris guard. A dirty engine retains heat and can  
cause damage to internal engine components.  
[ ] HARDWARE: Check all nuts and bolts to be sure that the components are secure.  
[ ] FRAME: Check all welds to be sure that the frame is in tact and secure.  
[ ] BLOWER HOSES: Inspect the blower hoses for holes, frayed, worn, kinked, or abraded  
areas. Replace any damaged or worn hoses. See page 36.
