Loaner

Hello,

I have a gator I am borrowing from a friend.

I have no idea what it is. Here is the code under the passenger seat:

v006x4x05887

The rear right wheel makes a grinding sound at times. The issue is intermittent. I "gun" it and top out at 10-15 mph when the thing is making the noise, when it is not making the noise or feeling like it is "stuck" I get to 25-30 mph.

Any ideas on what model I have and what issue I could be dealing with?

Thank you in Advance
