hi. i have a 2010 mudpro that i used to pull a moose up to the road last fall and its got a prob. as i was pulling said moose in reverse up to the road something let loose on the right side. i had all i could do to get it loaded onto the trailer. it sounded terrible like a clanging noise and would stall if i let off the gas at all to try and drive the atv onto the trailer. needless to say i have not had a chance to look at it yet so was looking for suggestions where to start. clutch maybe ??
