Backhoe lifting tractor ... digging force?

Most backhoe work has the tires off of the ground so the machine can be levelled, reduce forces on the drivetrain and anchor the backhoe in place.

Most backhoe work has the tires off of the ground so the machine can be levelled, reduce forces on the drivetrain and anchor the backhoe in place.

I have seen construction operators (? the operator status) jack the backhoe up as high as it would go with all front and back wheels more than a foot off the ground. I dont see any need for that unless you are trying to get clearance to get over a wall or something.

I jack my TLB up enough to level it and just enough to take a bit of weight off the tires and settle the stabilizers in the dirt on the high side. Anything more is just wasted hydraulic power and time. Sometimes this requires the FEL bucket to be in full dump mode in order to raise the front up enough for the TLB to be level.

It's just to reduce wear and stresses on the wheels, but here I have not seen a backhoe in commercial use the last 25 years. It's a dead machine type.

Having been a trainer back in the day, the recommended practice was to transfer the weight of the Tractor-Loader-Backhoe to the stabilizers (and the loader bucket which was flat on the ground) to create a stable operating platform, much as Gary described above. Jacking the backhoe all the way up also reduces digging depth by the amount the tires are off the ground.

Not that this will add anything of importance.....but I do want to say that resting the front bucket on the ground substantially firms up the machine.

When I'm using mine for whatever purpose.... I can always tell when the front bucket isn't on the ground, the shake that will go through the machine is much higher. So I reach backwards, push lever until I feel it pressure down....and continue.

For me, it's almost like driving without a seat-belt on.... I feel (to use an odd word) naked and vulnerable. Put seat belt on and everything is right. With the bucket off the ground, it feels vulnerable.... push it down and all is right.
