Replacement Rotary Cutter gearbox, 40hp rated, 1-3/8" smooth input shaft with 1/2" shear bolt hole and circlip groove, 1.57" X 12 tapered spline output shaft and 1:1.47 speed up ratio. These gearboxes have a square housing configuration and are identical in mounting and ratio to the round configuration gearboxes. These are original equipment gearboxes on the World Agritech Corp / International Machinery IM400, IM500 and IM600 series rotary cutters. This gearbox will not fit the IM402, IM502 and IM602 models as they have a splined input shaft! If your gearbox has a 12 spline output shaft and a 1-3/8" smooth input shaft with a shear bolt hole and a snap ring groove this gearbox will work. Bolt pattern is 4-3/4" on center hole to hole and 6-3/4" center to center of bolt hole on diagonal. The mounting holes form a square bolt pattern.
*****Please note this gearbox is shipped dry and will require 16 ounces of 80 weight gear oil or heavier!*****
