I've had my 850 parked in the garage for a few days, drove it in just fine. Checked my oil, gased it and fired it up. Let it idle for 3 or so minutes, get on it. release the brake and shift into reverse. Let off the clutch and it barely moves. Mind you I'm in Low, but, this thing would jerk a little and move much faster than it is now.
I checked the belts and put it in 1st and it moved just fine.
What should I be looking for here?
