NEUTRAL ADJUSTMENTS – DRIVE:
1. Raise the drive wheels of the mower off of the
ground. Safely block the frame in this position
so it is secure.
2. With the unit blocked up securely and the
arms in the neutral position (in the lock out
position) sit in the operators seat and start the
engine. With the engine running release the
park brake and check to see if there is any
wheel creep (any rotation).
3. If wheels rotate with the control levers in lock
position, stop the engine and remove the belt
cover between the seat frame and engine by
removing the 2 - ¼ x ¾ bolts.
4. All neutral creep (rotation) should be adjusted
out of the drive. This adjustment is performed
at the adjustable Pump Link on each
corresponding pump. ( See fig. ) Loosen the
jam nut between the ball stud and the control
rod. Tread the stud into the control rod if there
is forward rotation and out of the control rod if
there is reverse rotation. Never adjust the link
more than 2 full turns at a time. Retighten the
jam nut and start the engine, and repeat step
#2.
5. If the wheel still rotates in the Neutral Lock
position with the brake OFF repeat step #4.
TRACKING ADJUSTMENT:
If the machine pulls left or right on a level, flat
surface begin by checking the tire pressure. The
front tires should have 20 to 22 PSI and the rear
tires should have 12 to 14 PSI. If tire pressures
are correct examine the dampening cylinders. The
cylinders are preset from factory to limit the
forward motion of the control levers. (When the
control lever is at full speed, all the way forward in
the control slot, the damping cylinder should
bottom out.) To adjust tracking, loosen the two
bolts on the cylinder adjusting plate. Push
adjusting plate to move the cylinder forward on the
fast side. This will restrict the movement of the
control lever to even out tracking. Always slow the
fast side of the machine down if tracking is
necessary.
Note:
On uneven surfaces the operator is
responsible in keeping the machine traveling
in a straight line.
DRIVE ADJUSTMENTS:
If the mower is not tracking straight or if the unit
creeps in the “Neutral Stop” position proceed with
the following instructions.
TIRE PRESSURE:
Checking air pressure in the tires is critical for
proper drive or tracking.
NOTE: DO NOT ADD ANY TYPE OF TIRE LINER
OR FOAM FILL MATERIAL TO THE TIRES!
Excessive loads created by foam filled tires may
cause failures to the hydro drive system, frame
and other components. Foam filling tires will void
warranty.
Front tires: 20 to 22 psi
Drive tires: 12 to14 psi
