Massey Ferguson, John Deere, Case IH. Tractor parts and attachments Home Clutch Transmission Gearbox Diesel Engine Front axle Steering Rear axle Hydraulic Brakes Tractor split Powershift Gearbox The AG150 and AG250 Powershift gearbox comprise forward and rear housings containing seven shafts and nine clutches. Six speed clutches and three range clutches. Three clutches must be hydraulically engaged in order to transmit engine power. These transmissions are fitted with their own Gerotor hydraulic pump, filter, pressure regulating valve, lubricating metering valve and nine proportional solenoid valves to engage the clutches. These transmissions use an oil tank that is common to the gearbox and axle assembly. The gearbox is coupled to the engine via a splined coupling shaft situated in the transmission and a damper located on the engine flywheel. The AG150 and AG250 Powershift gearbox have the following characteristics: 18 forward speeds 6 or 8 reverse speeds constant meshing, helicoidal gears ball and roller bearings to eliminate all vibration common axle / gearbox oil tank hydraulically controlled multiplate clutches electrohydraulic gear changes 100% modulated gear changes adaptation to speed of movement reverse shuttle compact design in a 2part housing housing also acts as the tractor chassis between the engine and rear axle unit pressure lubrication of all clutches selfcontrolled hydraulic pump vibration damper in the engine flywheel electronically protected.
