A question for the experienced 3 point operators.
I have a box blade I pull with a New Holland TD75D and each time the back tires go over a raised area it dumps some of the load and after a few minutes of work it looks worse for smooth and level than when I started. Is there an answer for this constant up and down movement that tends to follow the tractor ups and downs?
Experience doesn't seem to be helping the situation.
When using my boxblade I go slow enough when doing finish grading to constantly adjust the hitch height. You can also run in reverse but preferrably only when finish grading loose material to prevent machinery damage. With topntilt you can make minute adjustments on the fly too, roll the box back and take less of a bite.
A landplane such as the larger one I built would work well for your tractor, this one is 8' wide and the boxblade is 7' wide. A landplane with skids or maybe add skids that are detachable to your boxblade would make dealing with washboard alot easier.
