Grading controlling box blade height

[minton]

On a MF-135, how do you keep the box blade at the same level/height? When box balding my road, it rises and lowers creating gouges and high spots.

If I turn, the blade will rise and then lower after I straighten out the tractor.

Yesterday I tried to clean up small debris in the woods and ended up with mounds of stripped top soil.

I tried adjusting the controls and made it worse. Also noticed if you speed up when the tractor needs more rpm's to pull what you have in the blade,

the blade will rise and leave most of what you gathered.

There are some excellent suggestions in this thread:

This is why many people are trading in their box blades for land planes for driveway and road maintenance. Check out land planes and watch some videos and see if these might be a better option for your needs.

Is this an old MF135? If so, it should have draft control and position control on the 3pt?

If working properly, position the height of the 3pt arms with the position control lever and they should never change height in relationship to the tractor's plane.

If working properly, position the height of the 3pt arms with the draft control lever and they should maintain their height based on load. More load will cause the 3pt arms to rise to relieve the load from the struggling tractor. This feature is normally used when pulling a moldboard plow.

Are you using the correct lever when trying to control the 3pt?

I can't think of any reason for the arms to lift when you are turning a corner?? Do you have the sway bars or chains snug so the box blade stays centered behind the tractor?

Curious to hear the solution to this scenario.

Do you have a hydraulic top link ?

If working properly, position the height of the 3pt arms with the position control lever and they should never change height in relationship to the tractor's plane. That ain't happening.

Are you using the correct lever when trying to control the 3pt?. Not sure, there's a lever that raises and lower the implement, then another one that controls how fast the implement raises or lowers. Another round knob slides up and down and limits how high the implement raises.
There is a screw with a spring on it that you can slide up or down also.[

Do you have a hydraulic top link ?...there is a hook up for a hydraulic line behind the seat.

Without a hydraulic top link...trying to use a box blade on anything but an already well established lane is going to be practically futile...

Without moving the box blade up or down...the top link can be constantly changed from a cutting action to a leveling and smoothing action simply by lengthening or shortening the top link...it is about impossible by manually changing the top link...

That's not true. Tractors have been used for smoothing work decades before hydraulic top links were thought of.

They make it easier. But aren't necessary.
