Deck Height Index, Deck Lift Handle, Ignition Switch

NOTE: References to LEFT, RIGHT, FRONT, and REAR indicate that position on the tractor when facing forward while seated in the operator’s seat.

A. Deck Height Index

The deck height index consists of six index notches located on the front/right of the seat box frame. Each notch corresponds to a 1/2 inch change in the deck height position ranging from 1-1/2 inches at the low- est notch to 4 inches at the highest notch.

B. Deck Lift Handle

The deck lift handle is located on the front/right of the seat box frame, and is used to raise and lower the mower deck.

Pull the handle to the left out of the index notch and push downward to lower the deck, or pull upward to raise the deck. When the desired height is attained, move the lift handle to the right until fully in the index notch.

C. RH and LH Drive Control Levers

The RH and LH control levers are located to each side of the operator’s seat. These hinged levers open out to the side in the neutral position to permit the operator to be seated or to leave the tractor seat. The levers must be fully opened out in the neutral position to start the tractor engine.

Each lever controls the respective RH or LH transmis- sion. Consequently, these levers control all of the movements of the tractor. Driving and steering utiliz- ing these control levers is quite different from conventional tractors, and will take some practice to master. Refer to SECTION 2: OPERATION for instructions on using the control levers.

D. Ignition Switch

The ignition switch is located on the RH console to the right of the operator’s seat.

The ignition switch has three positions as follow:

OFF

STOP

START

Figure 5

OFF - The engine and electrical system is turned off. ON - The tractor electrical system is energized. START- The starter motor will turn over the engine.

Release the key immediately when the engine starts

NOTE: To prevent accidental starting and/or battery discharge, remove the key from the ignition switch when the tractor is not in use.

E. Power Take-Off (PTO) Switch

The PTO switch is located on the RH console to the right of the operator’s seat.

Figure 6

The PTO switch operates the electric PTO clutch mounted on the bottom of the engine crankshaft. Pull the switch knob upward to engage the PTO clutch, or push the knob downward to disengage the clutch.

The PTO switch must be in the "disengaged" position when starting the engine.

F.Transmission Bypass Rods (Not Shown)

The transmission bypass rods (one for each the RH and LH transmission) are located beneath the frame platform, just inside each rear wheel.

When engaged, the two rods open a bypass within the hydrostatic transmissions, which allows the tractor to be pushed short distances by hand. Refer to SECTION 4: MAINTENANCE for instructions on using the bypass feature.

WARNING: Never tow your tractor. Towing the tractor with the rear wheels on the ground may cause severe damage to the transmissions.

G. Cup Holder

The cup holder is located toward the rear of the RH console to the right of the operator’s seat.

H. Storage Tray

The storage tray is located at the rear of the RH console.

J. Seat Adjustment Lever (Not Seen)

The seat adjustment lever is located below the front/ left of the seat. The lever allows for adjustment of the fore to aft position of the operator’s seat. Refer to SECTION 3: ADJUSTMENTS for instructions on adjusting the seat position.
