discharge chute. Do not operate mower unless  
1. Read these safety instructions and  
engine manufacturer's operating and  
maintenance instructions that are  
furnished with the mower.  
2. Discuss proper maintenance with your  
Dixon dealer, to save money and prevent  
injury. Consult your dealer before  
removing any parts.  
3..Don't allow anyone to operate your  
Dixon mower without proper instruction.  
Young children should never be allowed  
to operate any power mower, riding or  
walking.  
4. Before mowing, pick up all debris —  
particulary stones and sharp objects.

deflector is in place.  
7. Use extreme caution when mowing hills or  
slopes with any mower.  
8. Always disengage blades before taking the  
mower across walks or objects that project  
above the surface.  
9. When the mower is not in use, turn the engine  
off; never leave the engine running unattended.  
Your Dixon mower is equipped with a weight-  
sensitive switch that kills the en gine when  
operator leaves the seat while blades are  
engaged. Test this important safety feature  
before each time mower is used. This may be  
done by starting engine, engaging blades and  
then rising slightly from seat. If engine does not  
stop, see your dealer for necessary repair.  
10. Before adjusting your mower or adding fuel,  
turn the engine off. Let it cool, and disconnect  
the spark plug so the engine cannot start by  
accident. Be sure all moving parts are stopped.  
11. Never run the engine indoors; the fumes are  
dangerous.  
12. Before backing your Dixon mower, stop, turn  
around, and look.  
13. Gasoline fumes are explosive; use only  
approved gasoline containers to store small  
amount of fuel. No special oil/gas mixtures are  
needed for your Dixon mower.  
14. If the mower should start vibrating, stop the  
engine immediately and check for damage or  
loose parts. Vibration is usually the warning of  
trouble.  
DURING MOWER OPERATION  
1. The revolutionary Dixon mower attracts  
many admiring neighbors. But when  
mowing, all persons  
especially  
children — and pets should be cleared  
from the mowing area.  
2. Wear appropriate, safe clothing when  
mowing — close-fitting jeans or slacks  
and heavy leather or safety shoes with  
rough soles. Never use any kind of  
mower with bare feet or open sandals,  
not even an old push-type model!  
3. When grass is wet or slippery, do not use  
any riding mower.  
4. Always mow at the slowest speed that  
will cut satjsfactorily.  
5. Keep hands and feet away from the  
blade at afl times.  
15. Never lift lawn mower by the body; lift only by  
the frame.  
16. Never carry passengers.

IMPORTANT OPERATING  
INSTRUCTIONS  
rearward.  
Dixon ZTR mowers offer a new concept in mowing,  
providing unique maneuverability and ease. The  
following procedures will allow one to become  
familiar with the unique method of control very  
easily.  
TURNING  
Turning is controlled by moving one drive lever  
slightly forward or rearward of the other. To turn  
left, move left lever rearward of right lever. To  
turn "square corners" move lever of desired  
direction to neutral. To turn on mower's own  
axis (Zero Radius) reduce speed and move one  
lever to reverse position and the other to forward  
position.  
1. SET PARKING BRAKE — Be sure that drive  
levers are free and in the neutral position.  
(When drive levers are released, they should  
return to neutral position.)  
2. "Blade Operation" lever is to be set in the  
"Disengage" position.  
3. Move throttle control to "Choke" position.  
4. To start models with electric starting, simply  
insert ignition key and turn to the far right  
position. When the engine starts, release the  
ignition key and it will remain in the "RUN"  
position. To stop the engine simply turn the key  
to the "OFF" position.  
BRAKING  
To brake mower, move both levers in direction  
opposite of travel, release levers to neutral, set  
parking brake. When stopping on incline, it may  
be necessary to hold slight pressure on levers  
in direction opposite of slope, until parking  
brake is set.  
ALWAYS SET PARKING BRAKE BEFORE  
DISMOUNTING.  
NOTE: Some electric start models are also  
equipped with manual start provision.  
To start engine manually turn switch to  
"RUN" and pull the starter rope.  
INITIAL OPERATION  
It is recommended that first operation of mower  
be done at a slow throttle setting with mower  
blades disengaged u ntil operator is thoroughly  
familiar with the unit.  
5. Set engine to desired speed by adjusting  
throttle control. (Suggest set at slow speed  
during initial operation.)  
6. NOTE SAFETY FEATURE: Safety switches  
stop engine when operator leaves seat while  
blades are engaged, and engine cannot be  
started when blades are engaged. OPERATOR  
SHOULD TAKE PRECAUTIONS AND NOT  
RELY ON SAFETY SWITCHES.  
7. This unit is equipped with a unique transaxle that  
requires only two drive levers to control braking,  
turning, direction and acceleration. TO GO  
FORWARD  
From neutral position gently push both drive  
levers forward; to increase speed move levers  
further forward.  
You may have a tendency to "over  
control" mower at first. Slight movement  
fingertip control  
is all that's  
necessary for easy operation.  
8. Mower Blade operation:  
• Cutting height is set by positioning the  
adjustment lever. Push button knob on top of  
lever, set desired cutting height, lock in to  
position by releasing button knob.  
• To start mower blades, move lever on floor to  
"engage" position. To stop mower blades,  
move lever to "disengage" position.

terminal. (See also wiring diagram shown on  
Body Assembly illustration.)  
3. Clean top of battery and terminals.  
4. Do not remove battery from mower.  
5. To reactivate, reconnect cables to correct  
terminals and charge battery if needed.  
9. Parking Brake:  
Parking brake is on right hand side of floor area and is  
engaged by pushing full forward with foot. To  
disengage, pull lever back toward operator by hand. In  
emergency situations, brake may be used in  
conjunction with the natural braking of the transaxle by  
applying pressure with foot. Always set parking brake  
before dismounting. Be sure that parking brake is  
disengaged before moving.  
BELT ADJUSTMENT  
The best tension for a V-belt drive is the lowest  
tension at which the belts will not slip under  
normal load condition. Check the tension on a  
new belt frequently during first hours of operation  
and every 10-15 hours or monthly thereafter.  
Too much tension shortens belt and bearing life.  
Too little tension causes slippage and loss of  
power. Be sure that belts and pulleys are kept  
free of foreign material. If belt slippage occurs,  
tighten it just enough to prevent slippage.  
MAINTENANCE  
BEFORE PERFORMING ANY MAINTENANCE,  
SHUT OFF ENGINE, ALLOW TO COOL AND  
DISCONNECT SPARK PLUG.
