Owner of a new TV450. 200 hours. During a recent pond project I was working on I noticed the drive power seemed to be get weak and very slow. Very slow to climb the pond dam bank with a bucket of dirt and struggling to go much faster in 2nd speed than 1st on flat ground with a bucket of dirt. Now I have noticed that the drive motors also seem to give out easily under a hard push. For example if I'm pushing into hard packed clay the drive motors stop and rpms draw down slightly. Same if pushing into a tree to push over. The drive motors are not strong enough to break the tracks loose when pushing into a solid object on dirt or grass. Does this seem normal? Tracks are sawtooth so great grip in dirt but would think a 90 hp machine should have enough torque to break the tracks loose in dirt before giving up. Yes or no? Dealer is telling me no issues and pressure checks out ok
