1999 TG525. Been running daily for the last 5 yrs but am getting out of grinding industry. Head gasket was replaced just prior to when I got the machine and shortly after that the crankshaft broke, crankshaft was replaced with brand new one from (Highway and heavy parts) along with all new bottom end bearings. Has somewhere between 2-3k hrs since all that happened. It has a upgraded PtTech Hydraulic clutch on it. Tub and floor are fairly new with roughly 3-500hrs of use. Grinder runs great and is ready to go to work. Hrs will likely go up as I still use it now and then.
