I have one of these for a fast-hitch 140. The mower had much weather-exposure damage before I got it, part of a tractor-implement package deal. With shipping, a new discharge chute #26521 is about $40.00. The old one is so bent and rusted away that part of the shape is difficult to determine. This chute is on the left side of the mower. The online information appears to show a flange down on the front of the chute, but the rear has no flange, just a flat top of the chute.
Any information about the chute that you can offer will be appreciated. I am going to repair/reconstruct the one I have.
I just replaced the belt on the mower, not really a fun job. The belt consumes considerable power as it bends and twists. The new belt is so stiff as to stall the engine unless it is running above idle speed. Leaves less power for cutting the grass.
Luck favors those who are prepared
