Abstract
An auxiliary speed change mechanism (10) disposed within a rear portion of a tractor clutch housing (1) is supported by a support frame (11) comprising axially spaced front and rear bearing support plate members (11a, 11b) which are integrally connected by upper and lower connecting plate members (11c, 11d). The change mechanism includes two sets of constant-mesh gears (8, 9, 12, 13) and is operated by a shifter fork (17) which is supported by the support frame through a guide shaft (16). This structure facilitates an easy pre-assembling procedure of the change mechanism which is then installed into the tractor by securing the support frame to a front of a transmission casing (3) to be secured to the rear of the clutch housing. An integral, internal partition wall (1a) is provided in the clutch housing for interrupting lubricant oil for the change mechanism from a main clutch (2) which is disposed within a front end portion of the housing.
