On my 1954 TO-20 when you drop the lever to lower an implement to the ground that is attached to the three-point, should there be a "hover" point that corresponds to how far the lever is moved? When I lower the lever farther down it just makes the implement go down faster and there is no midway point, so it drifts either up or down slowly depending on the position of the lever.

It sounds as you are talking about a position control lever and the TO 20 and 30 or the TE series did not have position control. Also you do not have a 1954 TO 20 as the last TO 20 was built in 1951. There are some units you can make your self or buy to give your tractor a position control. Those will be mentioned in the archives.

Congrats! Works normal! You might also desire to look into a transport lock mechanism also.

There is a dead spot on the Hydraulic Lever that will help, providing there isn't a leak on the system. If there is a leak there will be no dead spot because as soon as you stop the pressure to hold it, any pressure in the system is leaking away. You need to lift an implement and switch off the Engine and see if the 3 point drops, it should take about 10 mins to drop from fully raised, but this does vary greatly depending on how much wear there is and what weight you are trying to lift, this test is with a load of 500lbs which is a 2 bottom plow. It also depends on the implement you are using, there are quite a few variables here. The reason that the hydraulics do this is because it is a Draft Controlled system and needs pressure down the Top Link from the Implement to the tractor to control the hydraulics, as opposed to a position or height controlled system that would do what you are talking about, but often there is a method to enable you to work-around the problem. Only a Draft Control is suitable for implements working in the ground. and controlling the depth. If you will email me direct at the address below and tell me exactly what you are trying to do and the implement you are using I should be able to provide you with the information you need, but do carry out the test to see if it holds first and then tell me what it happens when you try it.
