I have been grading my backyard with a box blade. Cleared quite a bit of trees. After clearing, I started rough grading to find stumps that were missed by guy grinding or weren't grinded enough. Plucked them all out and everything was good. While grading back and forth, box blade hit a stump and I started to dig it out. There was an approximate 4" round stump sticking up. After digging, it was a small piece of a major tree or a mixture of trees with the stumps in a major cluster. Dug around it and have a guy coming in to grind it. While operating, was going in reverse and backed into the crater. Box blade was dead on top of the stump so rear wheels were suspended, front wheels spun. I was able to get out. Worked the 3 point lever up and down and used the FEL to raise lower and help me get out. Now it seems that when I am operating with the box blade, I have to push the lever more to have it come up. It might be me reading into it. I felt that before this I could feather the blade up under load and now it doesn't feather up unless I push the lever a bit and it comes up a lot. I put the machine on level ground and raised and lowered the three point. The first 1/4 of the lever does nothing when raising, but when lowering box blade on concrete it will lift the rear of the tractor a bit so I feel that's part of the dig in range. Took implement off and everything seems to raise and lower fine except for a little vibration noise. Those 3pt arms on the tractor do have a Little slop but snap rings are in and looks ok. Question is, if tractor was suspended by box blade on stump and FEL out side of ditch, would that weight damage my three point lift mechanism. Do they either work or fail? Did throw the lift lever back and forth while suspended and trying to get out. It had no effect with raising or lowering the tractor. but wondering if that kind of weight on the 3poimt lift could have affected anything. Have had so many little problems that were covered and many I fixed myself, hope I didn't screw anything up. Should have been paying more attention while going in reverse. Hopefully it's just me but it doesn't seem to feather up under load with box blade full utilL I lift it quit a bit.
Would really appreciate Any thoughts.
