I have an RTV 900 and love the diesel engine, the full hydraulic system with dump bed and the tractor like transmission. I havent had the hard to shift problems like some folks have reported. I do have to pull the pressure release nob to shift gears if on an incline but other than that, it shifts easy and has plenty of power in L and M range, not so much in H range but it still climbs my little hill to my house even in H, just have to back off the throttle a bit and it increases the power which is contrary to normal thinking. I have pulled dozens of sweet gum saplings out by the roots with it up to about 3" in diameter when the soil was damp. I love my winch which is indespensible for fence building. I can stretch a full roll of netwire to the breaking point with it without a problem and the hydraulic dump bed will dump anything that I have put in it without a grunt from full with rocks to full with dirt. I have the ATV type tires and traction is not a problem. The only negative is that the frame is so stiff that if you side cross ditches, it will teeter totter on you and just spin in the air till you hit the differential lock to pull you on thru. I dont have a soft soil conditions even in the spring areas, it pull thru easy without bogging but it is heavy and if you have soft clay, make sure you get a winch on it as someone said, it is a brick with wheels.
It just sips diesel. I have put over 80 hours on mine with only 2 refuels and that was refueling at 1/4 tank on the guage(it was full when I bought it) I bought mine used with 63 hours on it for $8500 which I think is a very good price. It was just like new then. It is a 2006 model and I have had only to replace the battery on it, and do the 50 hour service when I got it. I suppose if I had to haul people I would look at the 1140 like John Thomas but that long frame has to be pretty hard to maneuver in the trees. Mine is not easy as the turning radius is huge on it (another negative I suppose) but I wouldnt trade mine for a gold monkey. My BIL has a gator and I way prefer may RTV over it. I like the high roll bars as I can step in and out without whacking my head on the roof. I still have the cuts on my head on the roof from using his to feed his cows while he was away for Thanksgiving. The roof is just a bit lower than head height, just right to hit you in the top of the head when you reach into the bed for something when getting out of the driver seat. Also go for the glass windshield, they dont scratch up like the plexiglass.
