Hi all, I recently picked up a nice 1988 M929A1. Have only loaded it up about 15 times full of clay with my Komatsu PC128. Loaded her up full to the sides, which are stock, not extended and it dumped great. Kept the tail gate locked into the extender angle wings. Decided to haul a few large stumps and on one of the loads a rather large stump seemed to over control the dump body and made it go faster than the hydro system could push it. is that normal? I probally had it 3/4 way dumped and on way back down it felt like it free fell for a short distance. There are no leaks on the cylinder. Your input would be greatly appreciated.
