Abstract
A front and rear transmission casing are joined to form a single casing. Upper and lower input shafts are received and supported by the front casing. The lower input shaft drives a change speed gearing with a speed change shaft and a pinion shaft. The pinion shaft has a pinion gear located on a further end of the shaft and engages a ring gear of a differential. The upper input shaft drives a clutch driven shaft through a PTO clutch unit. A rear PTO shaft is driven by the clutch driven shaft and extends out of the rear casing. A mid PTO shaft is also driven by the clutch driven shaft and extends out of the front casing.
