The setting for the lever is 2.5" from the top, measure from the front of the lever when it is at the top and the 2.5" to the rear of the Lever when it is down the Quadrant. The problem you have is because the hydraulic system is a Draft Only system and requires some pressure down the Top Link to the Tractor to make it work like you think is should do. Check this, hitch a plow or similar to the 3 point and fully raise it, now stop the engine and see if the Hydraulics leak-down noticeably. There will always be some leak-down, but it may be too much and that is making it noticeable. Checking it like this the 3 point should take about 10 mins to drop fully, when new they take longer. It may need a valve changing, but this will depend on how fast it drops. If you email me and tell me what happens and how long it takes I will send you some information about repairing it or re-setting it. Why do you want the hydraulics to stay in one position, if you tell me what you are trying to do I may be able to suggest a work-around for this that will allow you to carry out whatever you are trying to do. If you are using a Bush-Hog and this is what is causing the problem,there is definitely an answer to that, so let me know...John(UK)...email@example.com
