[QUOTE="blackwahl62, post: 94160, member: 13451"] I know this is an old post, but I had the same issue after rebuilding rexroth pump, its the adjustment on the hp controller on pump, it is a pain to set. It kinda acts like a gear ratio adjuster for hydraulics once the machine goes under load, if its not adjusted properly it wont compensate, engine will bog out possibly stall just moving forwards or back. I have a pdf of service manual if anyone needs the adjustment specs, however you will need gauges and special equipment to dial in. [/QUOTE]
