STARTING THE ENGINE
4.4 
 CAUTION
DO NOT USE STARTING FLUIDS. Use of starting 
fluids in the air intake system may be potentially 
explosive or cause a “runaway” engine condition 
that  could  result  in  engine  damage  and/or 
personal injury.
Be sure the fuel shutoff valve, located behind the 
1. 
operator's seat, is completely open.
Sit in the operator’s seat, fasten seat belt and place 
2. 
the steering control levers in the neutral position.
Engage the parking brake.
3. 
Place the PTO switch in the disengaged position.
4. 
If the engine is cold, choke the engine as needed.
5. 
Move the engine throttle control to about half engine 
6. 
speed.
Turn the ignition key to the START position and 
7. 
release the key as soon as the engine starts. Do 
not hold the key in the START position for more 
than 15 seconds at a time. Allow at least 60 
seconds between each cranking attempt to prevent 
overheating of the starter motor. Prolonged cranking 
can damage the starter motor and shorten battery 
life.
Allow engine to warm before operating the mower.

GROUND TRAvEL AND STEERING
4.5 
- IMPoRtANt -
If  you  are  not  familiar  with  the  operation  of  a 
machine  with  lever  steering  and/or  hydrostatic 
transmissions,  the  steering  and  ground  speed 
operations  should  be  learned  and  practiced  in 
an  open  area,  away  from  buildings,  fences,  or 
obstructions.
Learn the operation on flat ground before operating 
on slopes.
Start practicing with a slow engine speed and slow 
forward travel.
Learn to feather the steering controls to obtain a 
smooth operating action.
Practice  operating  the  mower  until  you  are 
comfortable  with  the  controls  before  proceeding 
to mow.
FORWARD TRAvEL
To travel forward with the mower, disengage the parking 
brake,  pull  levers  inward  out  of  the  neutral  lock  position 
and  slowly  push  the  steering  control  levers  forward  an 
equal distance.  The further the steering control levers are 
pushed forward the greater the forward speed will be.  To 
increase the speed, push the steering control levers further 
forward and to decrease the speed, pull the steering control 
levers back.
To stop the forward travel, pull the steering control levers 
back to the neutral position.
To steer the mower left while traveling forward, pull the left 
steering lever back. The further the lever is pulled back, the 
quicker the mower will turn left.
To steer the mower right while traveling forward, pull the 
right  steering  control  lever  back. The  further  the  lever  is 
pulled back, the quicker the mower will turn right.
- Note -
Smooth  operation  of  the  steering  levers  will 
produce smooth mower operation. While learning 
the  operation  of  the  steering  controls,  keep  the 
travel speed low. 
- IMPoRtANt -
Do not travel forward over a curb. The mower will 
hang  up  on  the  curb.  Raise  the  deck  and  travel 
backwards  over  the  curb  at  a  45  degree  angle. 
(See  Figure  4-1  item  12  for  cutter  deck  raising 
description.)
