Steering/Tire problem

[moresmoke]

If it has limited slip differential as mentioned, is it a clutch type and is there friction modifier in the oil? Straight gear oil on a clutch pack will make it grab.

Do you have the loader on it? It needs all the weight it can get up front.

Kind of the nature of the beast, with the heavy backhoe the front end is going to be light.

Turning less than full hard right or left is probably something you have to get used to doing. Or get more weight up front, less weight behind the axle.

A locked up differential as others mention of course could be a problem. When turning sharp do the rear wheels go smoothly at different speeds as they should, or is there jerking or one wheel wants to drag, leave marks on pavement or gravel, etc?

Any xtra weight on the front end will help and make a difference, but it won't help you determine whether it's a balance issue or a locked up rear diff, which it could easy be. It should at least try to turn, even if it's poorly balanced, not just plow straight ahead.

If you look at pic very closely, i have an extended bucket piece on front loader, not that heavy but way out in front of C of G.
Havent noticed any problems with rear axle. I guess just turn slower and shallower

From what I can see with them lawn mower tires it will never turn. Getting a lug tire and a larger size is what I would do. Or a steering chain. Also crowd that back hoe in as close as possible. You got too much weight at the rear.

Unless you have something in that bucket, you've barely changed the CofG of that machine at all. Looks to me like the backhoe could still be cinched up some more. A couple of inches of sag in the main boom of the backhoe will make way more difference to the CofG than the arc of the front loader without load in the bucket.

Hi, You've all been great and suer responsive, appreciate that.
Probably new tires in spring will be first order of business. Look into bigger is better?
The backhoe i'll cinch up.
What is steering chain?
Thanks again

On a similar machine made by Case/Ingersoll and my little JD455 w/loader these have been the best tires I've found. Much better than mower type tires in these sizes, higher ply rating, stiffer sidewalls and fairly deep grooving.

Some sizes are tube type others tubeless.

I would not go to much bigger as then you will have the front to high and will look like it is catwalking all the time. Different tread would make a lot more difference. And yes you will find a gentle turn will bite better than a sharp turn.

I wonder if someone did not use gear lube with a friction modifier in rear end.

i did want to see the actual tread on them tires. also those tires dont look like they are from that machine as the yellow paint is lighter color on the rims. and going one size bigger is a big benefit. the front appears a bit lower as it sits, so u load up the bucket and you will also be lower yet with more with the swat. and a steering chain goes on the drivers tire as heavy truck use them so it bites in and turns on slippey mud or ice. plus as i say use your accelerator to your advantage, not just keep it wound up at max rpm on turns. thats why backhoes have a foot throttle. get a size bigger and lug tires and you will see the difference. i hardly think worrying about a diff has much to do here, and quite sure its just the standard diff.

One thing to consider is that backhoes like a JD 510 came from the factory with a 14.5/75-16.1 F3 industrial rib front tire. They didn't come with an ag type 3 rib or 4 rib tire or a lug tire. Google that tire size and pretty much all of the results will be F3 industrial tread. Weight in the bucket and slower more gradual turns would be my advice. That also helps keep from digging up the grass like you would with a 3 or 4 rib tractor type or lug type front tire. If you are using it in your yard and don't want to ruin your grass anyway. And as others have said, since it is supposed to use a limited slip differential, if that diff is binding it will want to push. Some new rear differential fluid with limited slip differential friction modifier might be in order.

The tire pic was already in my phone as I was thinking of getting new tires beforehand. As of now I'm still recovering from storm and havent taken a pic.

Bigger backhoes are also torque converter drive. There is a big difference between running one of them and a hydrostatic.

As far as tread pattern goes, my big backhoe has lug tires on the front and mostly does what it wants if 4x4 is not engaged.

tires i can see look stock for that machine my jd backhoe needs the help of independent brakes to turn sharply without them it will push, most industrial type tractors use flotation type tires

I think that may have been made in a trailer tire tread mold. Looks just like some 5.70s I have.. But they are 8"

Looks like a standard F3 industrial front to me.
