The center line of the input shaft is 7-1/4" above the bottom of the gearbox mounting flange. There is a gearbox mounting bolt hole directly under the input shaft and each hole is 90 degrees apart.

Note***:
If using this gearbox on a Super 11 Rotary Cutter please make sure your old gearbox has the 1-3/4" X 20 spline input shaft, some units were equipped with a 1-3/8" X 6spline input shaft and these gearboxes will not work without modification.
Note****:
Early Super 8 Rotary Cutters used several different gearboxes including this box and two smaller gearboxes, both of which had 6 spline input shafts. If you arenote sure if this is the right gearbox for your mower please contact us and let us help you select the correct one.
*****Please note this gearbox is shipped dry and will require filling with gear lube before using!*****
