Massey Ferguson, John Deere, Case IH. Home Clutch Transmission Gearbox Diesel Engine Front axle Steering Rear axle Hydraulic Brakes Tractor split AG150/AG250 Powershift gearbox Creeper Tractors fitted with an AG150 or AG250 Powershift gearbox may be fitted, according to options, with a creeper. This reducer unit (24) comprises a simple epicyclical gear train having a planetary carrier and crownwheel mounted at the front of the intermediate housing (19). It is controlled by a lever on the righthand side console in the cab that is linked via a cable to a link fitted on the front righthand side of the intermediate housing. This link moves the coupler control fork. The coupler, fitted with straight teeth, must only be engaged when the tractor is stationary. Operation The coupler (29) is integral via splines with the layshaft (30). The moving of the control lever to the "Snail" position moves the coupler rearwards and locks it to the planetary carrier (20) via coupler ring (22). The speed of the output shaft is 1/4 of that of the input shaft.

Lubrication The lubrication of the mechanical components of the epicyclical reducer gear is ensured by an oil splash. The drive pinion and the layshaft (30) have an axial drilled channel, this allows flow "D" from the righthand side hydraulic cover to lubricate needle bearing (34). The bearing supports the layshaft and permits a difference in rotation of the shafts when in the "Creeper" position.
