Have a bobcat Hydro wb model 930307. How can you tell if the hydro or wheel motor went out. I bought it used and cut for 2 weeks with it fine no major problems, but when i got it it pulled to the right side I adjusted the the linkage rod then and got it to run straight and had no problems i cut about 45 yards with it and the other day i cut 2 yards no prob got to the 3rd and it doesn't want to move. Jacked it up and the right side will fly and the left will barely turn. Any help would be great.
