I just bought an 07 rhino sport. 27'' mud lite radials all around. The guy I bought it from said that it has a new clutch in it. I am new to a rhino. This past weekend I went riding some pretty steep hills. In low range 4x4 I was running out of power. The engine was still running strong, but the forward momentum was gone. It stopped completely with the pedal to the floor. The belt was not slipping, at least I didn't think it was. No burning rubber smell. It seems like it takes a lot of RPM to get this machine rolling. Some stock rhinos I have driven take off as soon as you hit the gas. This one seems like it has to load up before moving. Pretty high top end speed, but no low end torque. Any suggestions about a fix for the problem. I will mainly be on the trails and hills with the occasional mud pit.
