REAR WHEEL TREAD ADJUSTMENT

The rear wheels are normally assembled in the narrow

tread position, shown in Figure 20. The wheels can be turned

on the hubs for a wider tread. The wide tread provides greater

stability on hillsides and on rough terrain.

Remove the wheel lug nuts, turn the wheels around with

the valve stems inward and re-assemble on the hub.

If Chevron tread tires are used, remove the wheel lug

nuts and re-assemble the wheels on opposite sides of the

tractor with the valve stems turned inward. Interchanging

the wheels is necessary to maintain proper direction of

rotation for traction tires.

MANUAL LIFT OPERATION

Manual Lift Lever {Figure 21) (Model S-10G only). To

raise attachment, depress thumb release and pull lever to the

rear until the locking pin engages in the proper quadrant

notch to obtain desired attachment height. To lower attach

ment, depress thumb release and push lever forward. After the

attachment touches the ground the force from the lift assist

springs will resist the forward motion of the lift lever. The

amount of resistance is relative to the spring adjustment.

The two springs shown in Figure 24 are used to provide

lift assist. The tension on these springs should be adjusted

using the chains shown in Figure 22, so the front mounted

attachments can be raised or lowered with the lift lever by

the operator.

The' center rock shaft shown in Figure 24 is used to raise

and lower the rotary mower. This rock shaft is connected to

the manual lift lever through the link. The connection at the

rock shaft is made through the slotted hole which allows

the rock shaft to move up and down when in the lowered

position, allowing the mower to float without causing the lift

lever to move.

The center rock shaft pan flotation spring, shown in Figure

24 provides mower flotation. The tension on the spring can be

increased or decreased by presetting the latch bar to a dif

ferent notch when the pan is fully raised. The bottom notch

provides the greatest flotation.

The front/center or rear rock shaft is selected for operation

by the manual lift lever by the lift selector knob. Figure 23.

To change selection, locate selector knob to proper end and

rotate the mechanical lift lever past the last notch to the

overtravel area. This allows the selector latch to change po

sition. This allows a rear attachment to be used without re

moving the front/center attachment, or vise versa.

HYDRAULIC LIFT OPERATION

The hydraulic lift system is standard equipment on the

S-14G.

The hydraulic control lever is located on the control

console, shown in Figure 2. It is a four position lever to per

form four functions, UP, HOLD, DOWN and FLOAT. The

normal out-of-use position is the "HOLD" position whereby

the attachment will not lower or raise. When it is desired to

raise the attachment, the lever is pulled to the "UP" position

and the cylinder is actuated to lift the attachment. When the

lever is moved to the "DOWN" position, the oil pressure in

the cylinder is reversed and the cylinder forces the attachment

down.

When an attachment is being used which is designed to fol

low ground contours, the lever should be placed in the

"FLOAT" position. The cylinder is then free to move as the

attachment position requires.

Figure 25 shows the components of the hydraulic lift

system. The hydraulic pump supplies the oil flow from the

oil reservoir/cooler. Oil flow to and from the cylinder is con

trolled by the valve.

When the cylinder is extended or retracted, the bell crank

pivots and raises or lowers both the front and center rock

shafts at the same time through the front and center rock

shaft linkages shown in Figure 25. The connection to the

center rock shaft is made through the slotted hole which allows

the center rock shaft to move up and down, allowing the

mower to float independent of the flotation provision in

the hydraulic system.

increased or decreased by presetting the latch bar to a different

notch when the pan is fully raised. The bottom notch pro
