        I am a new tractor owner (Jinma 354 with FEL and Vteks VT3S BH 3Pt mounted).  I've only used the BH once to dig a small trench in compacted clay.  I had a problem with the tractor walking during operation.

        The trench ran parallel to a rather steep drop-off.  I had the tractor turned perpendicular to the edge.  Even though the ground was flat, as I dug the tractor's rear wheels and the BH stabilizers would lift and the tractor would be drug closer to the edge of the drop-off, even with the FEL down.

        My question is, how should I set the 3 point, stabilizers, and FEL to minimize tractor movement?  Do you think I had the 3 point or stabilizers too high?  Too low?  Was possibly working too far from the tractor?

        Any suggestions or comments are welcomed, since I plan on using the BH again soon.

          Hi John, welcome.

          That will happen when you are working in caliche. It's actually telling you that you need a much bigger, say heavier, machine. One thing you can do is to float the boom while you're bringing in the dipper and curling the bucket. Not too productive but at least the tractor will stay on the ground.

            Bob,

            Thank you for the response.  I figured maybe the machine was just too small for the job.  I can tolerate the tractor moving, just not when its moving towards an embankment.  I think I understand your response.  But to be sure, what does “float the boom” mean?  Is it lifting the boom while curling?

            Thanks again for the advice.

              A neighbor has this same backhoe. With most of our area being rock, boulders and lava caps covered by 1-2' of “Central Oregon moondust” this is the smallest useful backhoe for the area in my opinion. I drove the tractor down to his house awhile back and drilled 20+ holes for his fence and he will reciprocate when needed.laugh If I was still living in the bay area or N central California these smaller tractor mounted  backhoes would be very useful, just not here.

                Tinbender,

                Thanks for the reply.  Hopefully my next project will be easier on my little rig.  Kind of doubt it since I'll be putting a new culvert under a packed gravel road.  Maybe I'll go a little easier and just clean out some drainage ditches.  It all needs doing cool

                  I probably jumped the gun a little because your hoe may not have a float detent on the boom valve (pull it back beyond the stop). If you don't have it you can just feather the boom just like you guessed.

                      Bob, thanks again.  The tractor in the video appears to have his 3ph lower (based on the angle of the stabilizers) than what I probably used.  I'll be sure to try it at a lower position.

                          Notice in the video that the dozer is parked on quite an angle with the nose high, so actually the hoe is high on the dozer. My head is almost even with the ROPS. Ideally though it is low on the ground.
