Tip & How-To about Troy Bilt Walk Behind Chipper/Shredder/Vacuum 205cc
I just purchased a used Yardman 24A-203C701 which, as the title states, has similar variants among other brands.
If you remove either hubcap from the pneumatic drive wheels, you may see the drive pawls with thin pieces of nylon (like a wire ty-wrap) sticking out either side. This is what passes for the engagement spring for the pawls. The fix is to remove each pawl and modify them as follows: Remove the nylon piece. On the rear side of the pawl, under the short end which engages the axle shaft, there is a place where you can drill a 1/8" pilot hole. Expand the size to 5/32" (the drill will want to catch on the pawl's metal, so drill carefully) and tap for 8-32 threads. Buy four 8-32 Allen head bolts which are 5/8" long and four 8/32 hex nuts. Using Loc-Tite on the threads, install one Allen bolt and hex nut into the front side of each pawl. When the threads are flush with the rear side of the pawl, tighten the hex nuts to jam the fastener in place. Purchase four small extension springs which just fit over the Allen bolts and which have just enough tension to pull the pawls into engagement with the axle shaft. The machine will then pull with both wheels but can still be turned and even pulled backwards.
