Anyone plow with your backhoe?

[wdchyd]

If your backhoe has work port reliefs (on the dipper especially) then it won't do harm....but most small backhoes don't have them

It creates induced load on the rods and can bend them if extended out, (the dipper cyl is extended all the way out when hoe bucket is close to machine)

it has the same effect as back dragging with your front bucket with bucket tilt cyls all the way out......Oooops....:ashamed:

I am apparently not educated enough on backhoes! ha ha what exactly is a port relief? would having port reliefs actually prevent damage to the rods?? where would I look to see if mine has any?:smurf:

You will bend the cylinder rods. As far as reliefs go, there is one that only works if the levers are engaged and the other is in case you back into something. That one will not blow if going forward.

... This all sounds like a good Idea, but one bad pass where you snag a large rock, or hit something too hard its going to ruin your backhoe. $$$$$$$$$$ at stake if you ask me. I would think it would be much more safe to use the backhoe like its designed to be used and just take your time 6 to 7 feet at a time. I don't believe the Cylinders or dipperstick can handle that much force and if not right away....eventually its going to cause problems. I would also be concerned about snagging a water line, gas line or anything else unexpectedly and causing a lot of damage if you are not absolutely positive where all lines are located. I HAVE seen that happen several times using a backhoe as a plow...

Fully agree. It's not worth it when you can easily reach the loader & hydro pedal from the backhoe seat position.

No worries about unexpected utilities around here, this area was wide open desert until two years ago. The only thing to worry about here is the septic lines, and those are pretty easy to spot.

I figured it's probably not a good idea but luckily I don't know what it's not supposed to do and I have insurance so I gave it a shot. This may be the only time I ever do that but it's kinda cool to know what's possible.

I'm sure it works but i think a used one bottom plow with a shear bolt will be cheaper in the long run than a bent rod/blown seal or worse. Usually stuff like this works the first time flawlessly tricking you into thinking it will work again. The second time you try it the pile will hit the fan and your moment of brilliance fizzles out. Been there and wrecked other stuff

I agree with Dave, unless it's potting soil, i wouldnot be trying that again.To much to go wrong.

I would not advise doing that, something bad is bound to be the end result

here's a good generic pix of a cross-section of a typical valve.......the work port reliefs (RC1700, RC1950) screw into where the load check valve is pictured

usually they do not come standard, but are an option.......tractor manufacturers use different valves but essentially they work the same

the work port will relief any excess pressure seen when the control valve is in the neutral position, like an induced load from external source (tractor moving)..........otherwise the main relief valve will by-pass oil back to tank (when using the valve spool under normal working operations

check out figure 6....item 9

http://www.phtruck.com/download/hvd/HVD-Service-Literature/Gresen-Spare-Parts/V20SpareParts.pdf

it shows the difference of the load check valve and the work port relief from a top view

the cavity for the check valve/work port relief will be inline with each spool they are protecting (front and back), sometimes different pressure ratings stamped on them too
