Operation - Auto transmission Throttle The Stealth is normally fitted with a hand throttle in the cab. However It is not possible to use a hand throttle for field use due to type of fuel pump fitted to the engine. Due to the design of the fuel pump governing system and the automatic transmission you will find that you have to "drive" the Stealth with the foot throttle. Try to anticipate tough spots and be ready to respond with relatively large movements of the throttle to avoid the engine losing speed. With a little practice you will find a constant speed can quite easily be maintained. The hand throttle is fitted to enable the PTO speed to be held at 540 rpm when stationary for self-filling the sprayer. Ensure that the hand throttle is returned to the tick-over position immediately after use. Do not leave the machine unattended when the hand throttle is being used.   Automatic transmission The automatic transmission features a four speed main gearbox with a torque converter and a two speed transfer box. A central differential in the transfer gearbox distributes power to both front and rear axles, providing permanent four wheel drive. Using the main gearbox in conjunction with the transfer gearing produces eight forward and two reverse speeds Main gearbox selector lever A spring loaded catch restricts movement of the lever, thereby preventing inadvertent gear selection. Lift and hold the latch whilst moving to the required position.             'P' Park In this position the transmission is locked to prevent the vehicle from rolling away. Select ONLY with the vehicle stationary and the handbrake on. 'R' Reverse Select ONLY when the vehicle is stationary 'N' Neutral Use this position when the vehicle is stationary and the engine is to idle for a prolonged period (eg. at traffic lights) 'D' Drive Select 'Drive' for all normal driving on the road; fully automatic gear changing occurs on all four forward gears according to vehicle speed and accelerator position < 10 >
