I recently got a 2008 RTV1100, it had come off a trailer at about 40mph and launched thru some small trees. There is no cosmetic damage and the engine runs fine, but it will not move and all fluids are at correct levels. I jacked it up in 2 wheel drive (engine not running) and can shift thru all the gears fine by manually rotating the tires (verified gears move with shifter plate off transmission). The engine shaft to the hydrostatic transmission turns with engine running. Once the engine is running I can no longer rotate the tires and if you give it throttle it will not move. Feels like the parking brake is on (no it is not). I think the HST is hydro locked some how but I am new to the HST world and looking for some help. I don't have a service manual, but it is going to be here this week. Thanks for any help!
