Working the 644lbh

Here a couple of pics of the 644lbh doing some work. I love the backhoe on this tractor. Now if it didn't set so low to the ground.

Keep the Peace :cop:

You could mount duals on it and get a little more flotation when you're in the soft stuff.

It's nice to see that backhoe in action @Harry ! Thanks for sharing. Now I want a small backhoe too!!! :wife: :wife: :wife:

I agree with Eugen I like seeing that backhoe in action! I hope to use mine soon!

I'd say it isn't so much about floating, as just general lack of ground clearance.

I had mine out this weekend digging out a drain line that was overcome by 40+ years of root growth. No photos sadly, the project escalated quickly to backhoe, and Partner rescue saw, and I was in no mood to be snapping pictures (went from an hour snake project, to 12 hours of dirt work, and plumbing)... However, just in positioning the tractor, and then getting moved around a bit by the hoe, I managed to get the front weight to drop down behind a tree root. Nothing gigantic, but enough to trap the tractor.

I would love to have our big hoe going, as it wouldn't have had that issue. On the other hand, I wouldn't have been able to get it to where I had to work, so ya gotta take the good, with the bad.

I agree with Toolslinger about the problem is ground clearnace on the 644lbh. I could spin the tires and with the 646 it would just sit there and not move.

If our tractors had a locking differential I don't think I'd be stuck in situations like I have been before with mine. Just a little slip on some loose soil and down it can go sometimes. Or even some wet solid ground and your staying where you are. Here's mine stuck once after trying to backfill a stump hole. Had to take a step back and analyze what direction I needed to go. There was 3 or 4 stumps I had pulled and the ground was soft. A little this and that with the backhoe and front bucket and I was out but really a locking diff would have cleared up alot of issues.Image

Locking differential would be nice to have. But if both wheels spin, you could slide sideways and be in worse shape. But locking differential would be a good thing in some cases. Split brakes are a good thing too. Slow down or stop the spinning wheel and the power goes to the other wheel with more traction. Having both these systems would be a good thing for these Case loader tractors or any 2 wheel drive tractor. Lazy front wheels don’t help a 2 wheel drive tractor either, as you can see in Jancoe’s picture. 4 wheel drive sure has lots of good benefits, but can get stuck too.

There now. I got a ramble in this week.
Have a good day gentlemen.

After putting hydraulic wheel brakes on Frankie I was able to stop wheel spin . Even though both brake calipers are controlled with one pedal the dragg created stop the slipping wheel from spinning and force both wheels to drive . Work surprisingly well considered not being individually controlled .

I’m only guessing and rambling here, but Harry’s 646 has the fairly aggressive tire which would make it hard to spin.
And I don’t know right off what rear tire height on a 646 is, but those tires look tall. Let’s say for ramble sakes, original rear tire height is 27” and the tires on there now are 31”, that’s quite a change in rear differential gearing, which would make it much harder to spin the tire. Like sorta going from 3:55 gears to 3:08’s.
Just my thought. Could be wrong.

Your on the right track, we swapped the 24" tires on our 555 backhoe with the 28" off the 4500. It makes a big difference in traction and float.
We have a lot of the swallow you up sand here, I end up like jancoes pic often. The nice thing with a hoe is you can usually drag/push/pull yourself out.

Harry's bigger tires help him but also take more power to turn them.

Ferguson tractors had that track set up too. That’s what they use to go to the North Pole in the mid fifties. Wouldn’t be my cup of tea doing that !

It's been raining almost everyday since I dug the trench. It filled up with water after a rainy day, then it rained again yesterday. I'm thinking about pumping the water out because it's backing up in the garden area. I can't imagine how much the garden would have flooded if I didn't dig the trench. :barf:

I'll bet that fresh dug dirt is like pudding Harry. :114:

You dug that trench right on time! Good that the garden is saved!

We had quite a bit of rain too, in the last few days. The hole left from the stump I dug out is full of water! My wife said, go ahead continue, we may as well have a swimming pool :rofl:

I put in an old sump pump that I use to drain the water off my pool cover. It took a few hours to get it to drain like in the pic. Yes it is like pudding out there. I was hoping to dry it out, but it's supposed to rain again tomorrow! :112: :pullhair:
