Trying to remove the right drive motor on my 751. I've removed all 4 bolts, the lower hydraulic hose and the smaller hose to the rear of the motor. Can't get my wrench on the top hydraulic hose, so I'm trying to pull the motor out for access. Problem is, the motor won't budge. I've attached a ratchet strap to it and pulled pretty hard with no luck. Any suggestions?
