Are you buying new or used ? Dpf aside they are probably one of the best machines we have added to the fleet. Customers love them. We have had Case, Deere, bobcat, kubota and a few yanmars over the past few years all new track skids added to the fleet have been tl8, 10, and 12s. I prefer the sitting position in the cab. You sit up higher and get a better view. Feels more comfortable to me. I can work the controls in a far more relaxed position. Undercarriages have been very durable so far. They seem to detrack less. The t590 650s we still got account for about 90 percent of the lost the track service calls we get. We do however get a lot of bent hand holds on the front as they are huge and a lot of bend front rops and busted front lights. The way the cab has the " visor " built into it people seem not to pay attention to that extra length. The only down side we have seen and get told alot from customers is the cab doors don't seal and more dust gets in. They do seem to be more dirty inside than the bobcats. But those are the only minor issues we have had so far.. They have proved to be rental tuff machines so far.
