  • Hyd will lift arms and with a 165# man on them. Put a 6’mower on and it tries but willnot lift. Vane pump. No leaks.

  • Remove a side inspection cover, try to raise implement, and look for leaks coming from top cover. Lots of fluid coming from top cover is a problem. Flow can't keep up with blown gaskets, leaky lift piston or cracked lift cylinder. Increasing engine speed may overcome the leaks with light implements, but the problem will only get worse until the cover comes off and problems are fixed.

  • If you don't find any leaks with the inspection cover off there is a good chance the problem is an old worn out vane pump. Run a pressure check on it to determine it's status.
