The main issues are:
1. plumbing
2. where am I going to sit and look over the work as I am doing it
a. I have to build a seat frame for it.
b. I have to leave the loader elevated to maintain a level plane at all
times which requires several adjustments of the boom and bucket/quick attach frame.
3. I have to raise. the backhoe and move it backwards every time I am done
trenching or excavating this portion of the work
a. I have to level the back hoe each time by lowering the boom, stabilisers and then again lowering
the boom then adjusting the stabilisers and I may just need to move the plywood pads
I have to maintain floatation and to prevent sinking as I dig in the dirt.
b. The dirt may be mud below the grade increasing the dirts suction which requires more breakout
force with the bucket cylinder as you cannot use the lower and upper boom to do this.
4. I have to run two two wire braid hoses to the rear remotes for the backhoe.
You need open center hydraulics for a back hoe to work.
