MOTION CONTROL STEERING ADJUSTMENT

1. Raise  the  drive  wheels  of  the  Zero  Turn

off  of  the  ground.  Safely  block  the  frame

in  this  position  so  it  is  secure.  This

adjustment  must  be  made  with  the  drive

wheels turning.

2. Remove  the  electrical  connection  from

the  seat  switch  and

temporarily

install  a

jumper  wire  across  the  terminals  of  the

wiring harness.

3. Loosen  the  jamnuts  on  the  hex  turnbuckle,

which  connects  the  lever  control  arm  to

the  pump  control  arm.  Note:  The  nuts  to

the  front  of  the  hex  turnbuckle  have  left-

handed threads. 

4. Start  the  engine.  Run  the  engine  at  full

throttle and release brake.

5. Position  the  control  levers  in  the  neutral

position.  If  the  drive  wheels  creep

(rotate)  in  the  neutral  position  then

lengthen 

or 

shorten 

the 

turnbuckle

assembly.  Make  the  adjustment  to  stop

the wheel from rotating.

6. Re-tighten  the  nuts  at  the  end  of  the  hex

turnbuckles  and  repeat  the  procedure  for

the opposite side of the unit.

7. Shut the unit off. Remove the jumper wire from

the wiring harness and 

replace

the connectors

into  the  seat  switch.  Never  operate  the  mower

unless all safety switches are operating properly.

DRIVE ADJUSTMENTS

Steering and motion controls should be uniform in all

forward and reverse speeds. From the reverse posi-

tion the levers should automatically return to neutral

when released.

TEST DRIVE OPERATIONS

Check air pressure in tires. Equal tire pressure is crit-

ical for proper drive operation.
1.  Raise  drive  wheels  off  ground.  Safely  block

the frame in this position.

2.  Put  control  levers  in  neutral  lock  position

(control levers swung outward).

3. Start engine. Wheels should not rotate. If one or

both  drive  wheels  are  turning,  perform  proce-

dures  under  “Motion  Control  Adjustment”  for

side(s) that wheel turns.

CAUTION

STOP THE ENGINE BEFORE MAKING AD-

JUSTMENTS.

MOTION CONTROL LEVER ADJUSTMENT

1. There are three lever height positions available.

Place the levers in the position that provides the

most confortable operating position for you.

2. Align  the  levers  front/rear  position.  With  the

levers  in  the  neutral  position,  loosen  the  hard-

ware  and  adjust  the  levers  by  tilting  forward  or

backward until properly aligned. tighten hardware.
