We had a Volvo 210BFX, good machine, really smooth. Really good track power for climbing around over stumps, up hills etc. There very similar to Deere's for smoothness in hydralics. that one in the picture is beat, look at the hockey stick guarding, and all the side panels have been replaced, and there not thin!
For Dirtman, you should pitch for a new deere 2154, wow you would not believe the quality and how heavy duty those things are built!
