and returning it again to the neutral position and locking it. Re-adjust for neutral if necessary.

Steering lever tension

Lever action should be positive and smooth, allowing free movement forward and back with very little or no side play. It should remain where set, when released from your grasp, anywhere in the forward travel position. If lever is too loose: loosen the jam nut on steering lever pivot bolt, tighten the tension nut to remove slack and tighten the jam nut (Fig. 5-7).

Purpose of this spring and connecting link assembly (Fig. 5-3) is primarily to provide the operator with a means of adjusting the rotational resistance of the T-bar handle. Before adjusting for rotational resistance, lock the T-bar in neutral and make sure the spring is vertical, (see previous step 7).

The spring may be tightened to increase the rotational resistance or loosened to decrease it to suit the operator’s comfort. Adjustment may be made by turning the nut (Fig. 5-3) to vary the spring tension until the operator is satisfied with the resistance to rotation. As a starting point, turn the tension adjusting nut (Fig. 5-3) until the connecting link compresses the spring 0.06"-0.10" (1-1/2 - 2 turns). Test neutral again by raising the neutral lock lever and moving the T-lever around and returning it again to the neutral position and locking it. Re-adjust for neutral if necessary.

IMPORTANT: The spring does not need to be very tight for this system to work properly.

On units with serial numbers after 11374 (last five digits)

To adjust the rotational resistance of the T-bar handle on these units, lock the T-bar in neutral.

The spring may be tightened to increase the rotational resistance to suit the operator’s comfort. Adjustment may be made by loosening the rear pump linkage nut (Fig. 5-6) and tightening the two spring nuts to compress the spring. When the operator is satisfied with the resistance to rotation, tighten the rear pump linkage nut. Test neutral again by raising the neutral lock lever and moving the T-lever around

Jam Nut and

Neutral Lock

Adjustable wear plates, attached to the front and rear neutral lock devices positions the control lever in neutral. Loosen the mounting cap screws and move the plate (holes are slotted for this purpose) to compensate for wear, or when tractor wants to creep when neutral locks are engaged. When plate becomes worn to the point that adjustment is no longer possible, it can be turned over to utilize the opposite side. Replace plate when both sides are worn (Fig. 5-7).

Parking brake adjustment

Occasionally check the parking brakes by engaging the parking brake lever; start engine and set throttle at slow idle. Advance steering control lever approximately 1” forward; brakes should hold tractor from movement.

When adjustment becomes necessary, disengage the parking brake lever and rotate the knob located on end of lever clockwise (Fig. 5-8).

Electrical system

A 12-volt, negative ground system is used for ignition and accessories throughout. The battery is located behind the hinged compartment cover on the left fender (Fig. 5-8). A BCI-group 24F battery is recommended for all-season use. The batteries recommended for the different machines are:
