NEVER wear open sandals or canvas shoes during  
operation. Wear adequate safety gear, protective gloves  
and footwear.  
DO NOT try to stabilize the machine by putting your foot  
on the ground.  
Never direct discharge towards persons or property that

Always wear safety goggles or safety glasses with side  
shields when operating mower.  
Always stand clear of the discharge area.  
ALWAYS disengage PTO, stop unit and engine, remove  
key, engage parking brake and allow moving parts to  
stop before leaving operator’s position.  
Moving parts can cut or amputate fingers or a hand.  
Wrap blade(s) or wear gloves to service. On multiblade  
mowers, rotation of one blade will cause all blades to  
rotate.  
Never engage PTO while raising attachment or when  
attachment is in raised position.  
NEVER place your hands or any part of your body or  
clothing inside or near any moving part while unit is  
running.  
DO NOT operate at too fast a rate. DO NOT change

parts during operation. Rotating parts can cut off body  
parts.

ALWAYS look down and behind before and while  
backing.  
ALWAYS keep body and hands away from pin holes or  
nozzles which eject hydraulic fluid under pressure.  
If equipment vibrates abnormally, stop engine at once,  
wait for moving parts to stop and remove wire from spark  
plug. Repair any damage before restarting unit.  
DO NOT touch parts which are hot. Allow parts to cool.  
ALWAYS keep hands and feet away from all pinch  
points.  
Take all possible precautions when leaving unit  
unattended. Shut off engine. Remove wire from spark  
plug and secure it away from spark plug.  
Fumes from the engine exhaust can cause death or  
serious injury. DO NOT run engine in an enclosed area.  
Always provide good ventilation.  
ALWAYS remove key to prevent unauthorized use.  
Know the weight of loads. Limit loads to those you can  
safely control and the unit can safely handle.  
Read, understand, and follow all instructions in the  
manual and on the machine before starting.  
Disengage PTO when attachment is not in use. ALWAYS  
turn off power to attachment when travelling, crossing  
driveways, etc.  
Understand:  
• How to operate all controls  
• The functions of all controls  
• How to STOP in an Emergency  
• Braking and steering characteristics  
• Turning radius and clearances  
Mow up and down slopes, not across them.  
DO NOT operate on slopes of more than 17 degrees.  
Use of a Rollover Protection System (ROPS) is  
recommended for slope operation. See Accessories on  
Keep safety devices or guards in place and functioning  
properly. NEVER modify or remove safety devices.  
Always wear a seat belt when operating unit using a  
Rollover Protection System (ROPS).  
Ensure Safety Interlock System is functioning properly.  
DO NOT operate unit if safety interlock is damaged or  
disabled.  
Keep all movements on the slope slow and gradual. Do  
not make sudden changes in speed or direction.  
Avoid starting or stopping on the slope. If tires lose  
traction, disengage the blades and proceed slowly  
straight down the slope.  
Start and operate unit only when seated in operator’s  
position. Steering control levers must be in neutral, PTO  
disengaged and parking brake set when starting engine.  
If you cannot back up a slope or you feel uneasy on it, do  
not mow it.  
Use care when approaching blind corners, shrubs, trees  
or other objects that may obscure vision.  
DO NOT park on slopes unless necessary. When parking  
on slope always chock or block wheels. Always engage  
parking brake.  
Dust, smoke, fog, etc. can reduce vision and cause an  
accident. Mow only in daylight or good artificial light.  
Avoid slippery surfaces. Always be sure of your footing.  
Use a slow speed. Tires may lose traction on slopes  
even though the brakes are functioning properly.  
DO NOT mow on wet grass. Reduced traction could  
cause sliding and effect the machine’s stability.  
Do not bypass transmission when on a slope.  
Watch for traffic when operating near or crossing  
roadways.  
Use extra care when loading or unloading unit onto trailer  
or truck.  
Never carry passengers.

Keep body and hands away from pin holes or  
nozzles which expel hydraulic fluid when under  
pressure. Use paper or cardboard, not hands, to  
search for leaks.  
Full Service Position: Slowly release frame after seat  
contacts foot board. Use care and be sure of your footing.  
Do not step on mower deck.  
Ensure all hydraulic fluid connections are tight  
and all hydraulic hoses and lines are in good  
condition before applying pressure to system.

steering lever to be adjusted.  
Steering system and Speed Selector components should  
be lubricated every 50 hours of operation or every  
3 months whichever comes first (Figure 10).  
5. Loosen tie rod jam nut and turn tie rod until steering  
levers are aligned.  
Lube fitting locations are:  
– front axle pivot (2)

ADJUSTING THE PARKING BRAKE  
WARNING: MOVING PARTS can cut or  
amputate body parts. ALWAYS wait for moving  
parts to stop before performing maintenance or  
service.  
The parking brake might need adjustment over time and  
after new brake pads have been installed.  
NOTE: After installing new brake pads in the calipers,  
they must be burnished by driving for a short distance  
(about 100 feet) with the brake on. To do this, bring the  
parking brake lever part-way up while driving in a straight  
line. This quickly breaks-in the pads for maximum effec-  
tiveness.  
CAUTION: DAMAGED OR WORN BELTS may  
result in injury and/or damage to unit. Check  
belts for excessive wear or cracks often.

With the parking brake engaged, the spring length should  
measure 1 1/2" between the jam nuts and the trunnion  
and the clearance between the return nuts and trunnion  
should measure 1/16 to 1/8" (1.59 to 3.18 mm). If either  
of these measurements is off, adjust the parking brake  
appropriately.  
CAUTION: Use care when releasing idler spring  
tension. Keep body parts well away from idlers
