John Deere 655c series 2 v pattern control?

Hello, I am brand new to the forum and had a couple of questions. Any information would be very much appreciated.

I am looking at buying a 2003 John Deere 655c series 2 track loader and plan on working it a little on the side with the hopes of making a little extra money, it has approximately 4600 hours on it with about 50% under carriage, the seller is asking a pretty reasonable price. I have ran a Cat 939 a little in the past with the joy stick control, I was wondering if the V pattern on the JD is something that is liked or disliked? how is turning with the steer peddles? Also are there any known problems with these machines?

Thanks.
