[QUOTE="Tazza, post: 2813, member: 82"] Under load its normal to slow down a bit, but it shouldn't fall really badly. It should still be able to lift even with a good load on it. I would suspect it to drop sharply if it was such a big load that the engine was about to stall. As for one side being affected and not the other it really does seem like the hydrostatic pump not the hydraulic/charge pump. You could try swapping motors over and see if its the motor. If it doesn't change, try removing the high pressure relief valves on the hydrostatic pump, cleaning and re-installing. Also do the cold weather by-pass ones. Basically the 4 bolts on the pump near where the hoses go down to the motors. There should be 2 either side. If thats not it, you may need to take the machine to your dealer for a flow and pressure test to check the state of your pump. I would leave this as an absolute last resort as i bet it won't be cheap. Remember the drive and hydraulic systems are seperate, what affects one shouldn't do anything to the other. I still think there is something there with your description of lack of lifting power. I take it the engine seems to be running well? and running at a good speed? Good luck on this one. Keep us informed. [/QUOTE]
