I feel therse belts had to have a high back in order for the reverse belt to hit the drive belt without the pulleys on the strap iron that holds the reverse mech and the gear shaft pulley on the trans. Anybody know the nomanclature for these belts.

Regular V belts fit flush with the rims of the pulleys, and the pulleys are situated so that when you pull the reverse knob and raise the end of the strap with the reverse V belt on it. That end pulley grinds on the large V belt pulley on the gear mech.

Pardon me for including another picture but it shows what I have. Just a gear box that includes reverse. My smaller one has no reverse. Would be interesting to see a picture of what your dealing with.

That brings back memories-we had the exact same walk-behind only single wheels-loaded. Had the reel mower, sickle mower and the blade. That thing would push some snow. That was 45 years ago......

Ive got one of those. Bought new tires for it. Couldnt get the origional size, so these are oversize. Ive givin it to my DD and her hubby. I think its a simplicity V

What im talking about is older.
The pulley comeing out of the engine has 3 or 4 different slots in it.2 of those have belts on them. The inside belt is fastened to a piece of strap iron at the engine and the stap hangs down when not in use at the outside end, under the drive pulley on the axle. There is a V belt on the pulley that runs the length of the strap iron to a pulley at the outside, swinging end. This belt is as tight as one can make it. BOTH belts are turning continually as the engine is running. AT THE OUTSIDE end of the strap iron is a little hole that a cable is affixed to. that cable runs up to a rod then to a knob. When wanting to back up, I throw one of the cast iron levers with a fist sized knob of cast on it forward, causing the pulley attached to the axle to move forward. This releases the tension on the drive belt. THEN I pull the knob with the rod attached to the cable that lifts the outside end of the strap and pulley and V belt up under a 2in flat spot next to the V part on the pulley attached to the rear end. When the back of the V belt below it is pulled up against that flat spot on the axle pulley, it causes the pulley to run clockwise, backing up the axle. Normally, with the engine, it runs counter clockwise.

This sounds like a Midland produced tractor - not Simplicity. Is the lower part of the handlebar a single oval tube?

Could you turn the OD of the reverse pulley rims smaller ? If it is steel you could have the grooves welded up and machined so the belt run higher in the groove.

I have one of these with a tiller on the back, and I could never quite get the belts to work right either. I have a hard time stopping mine. Really well built machine though.

well to adjust your model v . engage belt (not running) so it is tight . then adjust the bracket with the guides so that there is about 1/8 clearance between belt and guide should be just behind pulley for the top and same for bottom which is further back from pulley. the guides are the small diameter with springght looking ends that are bolted to bracket that r bent at right angles and extend over top of belt. u may have to make new ones. if u get it set right when u release the belt.the guides hold the belt just above the pulley top and bottom
