MAINTENANCE
Motion Control Linkage Adjustment
This adjustment must be made with the rear
wheels rotating. Raise the rear of the
machine and block it up so the wheels are
free to rotate
Place a 2 x 4 board between the foot plate
and the center of the seat to engage the seat
safety switch.
Loosen the nuts (A and B) directly behind
each ball joint on linkages (C). See
illustration.
Start the engine. The park brake must be
engaged and the motion control levers in the
neutral slots to start the engine. Run the
engine approximately half throttle. Release
park brake to allow the wheels to rotate.
Begin with either side and put the motion
control lever into the neutral position. Adjust
the motion control linkage by rotating the
double nuts (D) in the proper direction until
the wheel stops rotating. See illustration.
Move the motion control lever forward then
into the neutral position and place it into the
neutral slot. The wheel must be stopped
completely at this point. Now do the same in
reverse and release the lever. The lever
should return to neutral on its own.
Run engine full throttle to make sure wheels
do not rotate. Readjust if any rotation occurs.
Repeat the whole process for the opposite
side and tighten the nuts against the ball
joints.
Turn machine off.
Cutter Housings
Grease housings once weekly or every 40 to
50 hours of use. Use a good synthetic
grease. Pump grease in until a small amount
purges from the popet on the underside of the
deck. Check the torque of the pulley bolt 45 ft/
lbs should be maintained.
WARNING!
Keep hands, feet and clothing
away from rotating tires.
