There's a drain plug at the bottom of the lift-all pump/resevoir - that nodule that sticks down from the belly of the tractor just in front of the light switch support. The plug is just behind where those two keyhole-shaped holes are on either side of the tractor. Unscrew the drain plug and unscrew the filler cap (on top of pipe that sticks up on the right ('passenger') side just in front of the belt pulley mechanism). This will let air in to facilitate the draining and you can check to make sure the breather holes in the filler cap are open while you're at it.

The 1940's manual and purists say to use 30W _non-detergent_ oil in the hydraulic system. If you use 30W oil, make sure it is non-detergent (harder to find) as the detergent stuff will foam and the hydraulics won't work. After reading some posts here, I switched to using hy/trans oil (Wal-Mart is the least expensive source). If the system doesn't have any leaks, this oil works well and gives better wear protection in all temperature ranges. Also, if you switch implements between this and other tractors that use hy/trans oil, you don't have to worry about mixing unlike oils.

If the system doesn't have any leaks, I'd work it a bit and then drain and fill it again sometime soon to flush the age and wear sludge out - waiting until a rebuild to get it completely clean. If it does have leaks, it's only about $30 from Carter and Gruenwald for all the gaskets and balls and springs to rebuild it.

These are mostly my opinions on the matter but this should get you going.
