I went to move my 1999 komatsu pc200 while moving material and out of nowhere when I moved the drive handles the machine struggled to move. It felt like it had no power to go anywhere. It would crawl 2 feet very slowly, then struggle hard, then crawl 2 feet and struggle again. Idle is cranked up, both tracks are doing the same thing. Everything else moves fine with no problem; pistons, swivel. Any idea what this can be?
