I'm trying to work on a Troy Bilt tiller I got from my Dad. Having trouble finding tines and other parts. Also wanted to break it down and build it back up. If anyone knows where I can find a manual for this tiller it would help alot. The model number I found on the side of the manual start is HH60-105106F, and the serial number is 9121C at the engine and 413142 down near the wheel base. Also found a date of 7/16/79 on the case covering the pilly wheels.
