Ground Speed Lever Friction Device - MacDon 9250 Operator's Manual

Traction Drive: Ground Speed Lever
Friction Device Adjustment
The ground speed lever friction device maintains
lever position at the point in the forward/reverse
slot where it was released by the operator.
The friction device is located at the bottom of the
ground speed lever (A), under the cab. It has been
factory set as shown, where lock nut (B) is 0 to 1/8
inch (0 to 3 mm) from the end of the carriage bolt.
If the lever does not maintain its position in hilly or
soft-soil conditions it may be desirable to increase
the holding ability of the friction device.
NOTE: Increasing the holding ability of the friction
device also increases the amount of force required
by the operator to move the ground speed lever.
To increase friction device holding ability:
1. Tighten nut (C) until it "bottoms-out" on the
threads at point (D).
2. Hold nut (C) with a wrench and tighten lock nut
(B) against nut (C). Torque nut (B) to 60 - 70
ft.lbs. (80 - 90 N⋅m)
