A drive mechanism for use with an engine in combination with a rear engine power takeoff operatively connected to the engine before a transmission. The drive mechani sm has a first shaft rotatably connected between the rear engine power takeoff and an activator f or the drive mechanism and an adjustment gearbox operatively connected to the activator. The adjustment gearbox is rotatably connected to a second shaft extending to a driven gearbox. The second shaft is adapted for rotation up to a predetermined speed. The activator is adapte d to activate the adjustment gearbox, thereby operatively connecting the first shaft to the adjustment gearbox, and to de-activate the adjustment gearbox. Also, the adjustment gearbox is adapt ed for adjustment of the speed of rotation of the first shaft so that the speed of rotation of th e second shaft is within the predetermined speed. |
