Owner of a new TV450. 200 hours. During a recent pond project I was working on I noticed the drive power seemed to be 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. 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. 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.

I have not run that case machine and I do not know what type of tree or size of trees that you are trying to push. but a 90 hp machine operating as it should be a hoss. If the pressures are as they should be maybe it is the flow that is not right, a restriction somewhere?
A little more info. Loader has gone to the dealer twice with no noticeable change. First trip to the dealer they said it felt fine. No real testing was done other than pushing into a gravel pile. No change when I got it back so the shop manager and his tech came to the house to test. The tech is new and shop manager said he did not have a lot of experience in the field yet. Pushing into a tree the shop manager agreed that there seemed to be a power issue with the drive. The second trip to the dealer was the one referenced when they checked pressures, recalibrated the drive, and said it was performing better. Now on to today. Let the machine warm up and decided to do test a push into a smaller tree compared to my 65hp Kubota tractor with hydro for comparison. Video is below and you can see that my tractor is getting as much push if not slightly more into the tree based on the amount of deflection as the trackloader. Unlike the loader, my tractor has zero drop in rpm's before the tires break loose. The loader on the other hand drops rpms from 2500 down to 2080 and holds there as the drive gives up. I find it hard to believe that this unit does not have more pushing force than my smaller tractor. Tree is an oak and about 6-7" at the point I was pushing on and based on past experience this machine should have walked right through it. I guess more than anything I'm looking for confirmation from you guys as operators that what I'm seeing is not normal before pushing on my dealer to take a harder look. I can't recall in the past having issues loosing drive power. I've always lost traction before the drive would give up. Video - click for link
