We need more Info the help diagnose the problem. Does it make any sound when you try to raise it? Check under the seat on the Left side. There is a small lever that adjusts the lift speed, and IF I remember right it will lock the 3 point at one end of its adjustment. There is also a manual lock to hold the 3 point in the up position. It is the lever with the round black knob on the back near where the top link attaches to the tractor. If it is up the 3 point is free, down to lock.

The shorter lever on the right is the draft control. This should be in the depth control setting unless plowing, when it should be in load control. There is a small lever, more like a tab on the side of the rockshaft housing under the seat on your left. This controls the speed of the 3 point hitch. The hydraulic fill/dipstick is that small(about 1 inch high and an inch in diameter) cylinder on the top rear of the rockshaft housing. It doesn't take much oil to go from off the dipstick to overflowing. You need to get an operators manual ASAP. All these things I talked about are covered there.

As for the no hydraulics, check your hydraulic fluid level and fill as required. When full try hooking up the remote couplers to an implement and see if it works. If not, then the pump may have burned out from lack of lubrication(that happened to one of my 510's once).

The pump is located up front, ahead of the radiator. Look behind the front grill.
