Differential Lock Pedal, Hydraulic Control Levers

Differential Lock Pedal

Located at the rear of the right floor board, the differ- ential lock is used to gain additional traction when operating the tractor on wet or loose soil. When the pedal is depressed the rear wheels of the tractor are prevented from rotating independently of one another. See Figure 16.

WARNING: When operating with the differential lock engaged, the tractor will be difficult to steer. To prevent loss of control of the tractor, do not drive the tractor on roadways or at speeds above 5 MPH with the differential lock engaged.

•To engage the differential lock, lightly step on the differential lock pedal with your heel.

•To disengage, simple release the pedal.

Hydraulic Control Levers

The hydraulic control levers, consisting of the position control and draft control levers, are located on the right fender. See Figure 17.

Use these control levers to control the working depth and pull of implements attached to the three point hitch as follows:

•Using Position Control — This will control the working depth of 3-point implements regardless of the amount of pull required. Push the draft control lever forward to the lowest position and set the implement working depth by moving the position control lever to the desired position.

•Using Draft Control — Th is will control the pull of the 3-point implement. As the pull on the 3-point hitch changes due to various soil conditions, the draft control system automatically responds to these changes by either raising or lowering the implement slightly to maintain a constant pull.

Push the position control lever forward to the lowest position and set the implement pull by moving the draft control lever to the desired setting.

•Using Mixed Control — In draft control, when draft decreases, the implement automatically lowers to increase draft. However, the implement some- times lowers too much. To limit the degree the implement can be lowered, set the position control lever at the lowest working depth desired for the implement; then lower the draft control lever to the point where the implement is at the desired depth. This stops the implement from going too deep and also controls the pull to prevent loss of traction and ground speed.

Brake Pedal Lock

The brake pedal lock is located on the right brake pedal. Flip the lock counterclockwise so it engages the bracket on the left brake pedal to interlock both brake pedals. See Figure 18.
