I have a Troy Bilt horse that has 2 belts, one for the 2 blades on the deck and a drive belt that runs the hydrostatic transmission.
The transmission belt broke, and I can't figure out how to get to the rear portion of it that changes. I have linked to 2 pictures:
The one with the fain in it is an overhead view below the battery and on top of the transmission on the back of the mower.
The second is the breakout of this section of the parts list.
I need to take the nut on top of the fan off to get the belt around the pully (you can see the bracket that the pully sits "in" in the breakout. I have 2 problems:
How do I get a wrench around the nut above the fan? There's no room.
How do I keep that from turning? I can turn the fan by hand if the brake is on or not, and if the transmission is engaged or not. There is a pull-out lever that disengages the transmission, but that pully always freely turns so when I get a wrench around it I cannot stop the shaft and everything from turning.
How do I do this? Pictures are here:
