There is a hub welded into the pan with 12 tapered splines that measures 1.57" at the top. All 40 hp. gearboxes have a 1.57" X 12 spline shaft coming out of the bottom of the gearbox, gearboxes with a 2" x 15 spline shaft require a different stump jumper also available in our store.
Featuring twin vertical reinforcements to the cross bar to reduce the potential for bending or warping, and the addition of structural bends in the pan itself to strengthen the edges of the stump jumper pan. The hub that has been welded both on top and on the bottom for extra strength. If you look at most OEM and replacement pans the hubs are only welded on the top side, there are no vertical reinforcements to the blade bar and the pans have no structural bends making them much weaker than these heavy duty replacements!
