Greg,
Check for water in the hydralic fluid. If the fluid on the dip stick is a milky color, then that could be the culprit. If so, be prepared to change the fluid a couple of times before you remove all the water.
The oil should float on the water, however when you use the hydralic's it picks up the water and deposits in the most unlikely places.
Compiments of one of the old timers in my community.

To determine where the hyd system may be leaking, remove the RH inspection cover on the hyd case. You may then start the tractor at idle and raise the lift, using a light look inside. If the ram cylinder is leaking oil will be dripping/streaming from the area under the seat. If the vertical hyd tube is leaking a spray will be apparent. If the upper tube seal is leaking it will be under the front of the top cover at the front of the seat. If turbulence is seen in the oil at the bottom there's a leak in the pump area. There, the oscillating control valve may be the culprit, check it first, to avoid disassembling anything unnecessarily.

Could be the rings on your piston in the lift cylinder; that happened on mine. Take off the side cover with the dipstick, and with the pump on, look up with a flashlight. If you see a stream of oil coming down from above that's likely it.
If it turns out that that's what it is, you can use a piston from a Ford NAA, which has neoprene O-rings instead of cast iron rings. Assuming your cylinder is not scored, they apparently will make a better seal.
