1-17 EQUIPMENT OPERATION AND DESCRIPTION — CONTINUED

1-17.8 Drive Controls

Parking brake (1) — when set, moves brake apply lever to provide internal braking for right and left

transmission drive assemblies (2).

Brake pedal (3) — when depressed, provides internal braking for right and left transmission drive assemblies

(2).

Steering (4) — applies brakes to track on the inside of the turn. (Left turn — brake is applied to left drive output;

right turn — brake is applied to right drive output.)

Fuel shutoff (5) — when the fuel shutoff handle has been pulled out, it cuts the fuel supply and shuts down the

engine (6).

Accelerator pedal (7) — when depressed, accelerates the engine so the engine operates with greater rpm.

When the accelerator pedal is released, engine rpm will return to idle speed.

Hand throttle control (8) — is another method of controlling the speed (rpm) of the engine (6). (Push forward —

engine speed increases; pull back — engine speed decreases.)

Engine throttle control rod (9) — is the throttle linkage from the hand throttle control (8) and the accelerator

pedal (7).

Transmission shift control (10) — selects the speed range and the direction of the power output of the

transmission (2).

NOTE

The transmission throttle valve control rod (11 ) does not govern the speed of the

vehicle or the transmission rpm. Speed and rpm are determined by engine rpm and

the shift control (10) position.

Transmission throttle valve control rod (11 ) — is interconnected with the engine throttle control rod (9) and the

transmission shift control (10). With the engine operating and the shift control in the neutral position, the

transmission throttle valve is locked out. When the shift control is in one of the drive gears (or reverse), the

transmission throttle valve is locked in allowing transfer of power from the transfer assembly (12) into the

transmission and to the drive assembly.
