It took about half hour for the Bobcat to have problems then would not go forward or back.Motor runs great , bucket lifts up & down.I started the motor pushed the sticks forward & was being pulled for about 300 ft to the garage to work on it.tires rolled & pulled easily,no sliding.Then unhooked to come around to the front to push it into garage. pushed about 5 ft. then all functions came back better than they had been for a long time , forward , backward with lots of power.WHAT TOOK PLACE?can I use it now?or will I be stuck with the same problem later?Would the brass filter in the pump need to be cleaned?I and dealers can't figure this out .The Bobcat is a 732
