Is the belt slipping?

If it raises the head, sounds like the pump and all is working??

What head are you using?

Is the double "V" belt oily or worn (grooves in belt bottoming on "lips" at sides and center of drive pulley) making it slip easily?

Does lifting the header lug the slant 6 ?
Is the belt slipping on the pump pulley or on the motor pulley?
As preveiously asked. Has somebody operated the swather with old worn belts until the point of failure. Which has worn the pulley grooves?
Over tighening the belt tension is not a substitute for new pulleys.

Pull on the lever? Isn't the header and reel height controlled with rocker pedals?
How much spring pre-load is on the lift cylinders?

Is that pump mounted on the header and driven by the belts that run the head It may be the head drive belt slipping causing the pump to slow down.
