How to adjust clutch on troy built pony ?

SOURCE: replace pullcord on troy built mower

Replacing the rope is not difficult but tricky. I believe that your model has a fuel tank on top of starter cover, empty fuel and remove tank to expose starter cover. Remove the starter cover and place it on your workbench with the plastic rewind spool visible and remove the old rope noting how it was tied. The rope is sold in various sizes from # 3 to # 6.5. Most mowers use a #4.5, with length of about 6 to 7 feet. You may not need this much but more is better. Now practice inserting the rope thru the hole where it comes out of the cover into the hole where it ties on the spool. Once you can do this you are ready to wind. The spool /spring winds when you pull the rope, that why it recoils when you let go of the rope. With that in mind, turn (wind) the spool in the same direction that it turns when you pull the rope. It should be getting tighter as you turn. Keep winding in the direction that it turns when you pull the rope untill it will not go anymore. It should be very tight. Now unwind one complete turn and align the hole of the spool to the hole in the housing and hold it there while you insert the rope from outside hole into the spool and tie knot. After the knot is tied slowly let rope rewind into the spool untill it stops on its own. You are done. You should have plenty of extra rope left to extend out to the handlebar. Enjoy

You have to take off a part behind the gears and move it to a slot farther away. Mine was the same way. It's in the manual on how to adjust the speed to go faster.

remove the front black plastic plate that is stamped self propelled and replace the wheel drive belt that attaches the engine pulley (above blade) to the transmission pulley (found under the cover). When you buy the belts, pick up two or three as I seem to go through a couple per season. Hopes this helps
