Stuck Tractor

[JOHNTHOMAS]

Thanks for all the replies to my question. Learned a couple of things from the advice offered. Learned what regen is and how it works. I just need to get out and practice my technique. Last time I got stuck had to get a dozier in to pull me out. Thank God for friends.

My first Kubota was bought about 10 years ago when I started building my house on a treed, rocky, gullied steep hillside. It was bought to be my lifetime mower with a high priced wheelbarrow on the front. Had never owned a tractor nor knew anyone that owned a SCUT.
I did some work with it but had a man with a dozer do the hillside tree clearing and home site excavation (hit solid rock where my house is built). Neighbor started building at the same time and he had the same guy do his tree clearing behind his house and I moved back into the trees for my house site. Dozer pushed trees in a pile in the gully between me and neighbor but it was my gully. As time went on I started discovering I had a small working tractor with that wheelbarrow on the front and 4 wd. I'd attack that pile of trees evry so often and push the trees in neater and lifted some of them up to make the pile higher and more compact around the edges. Almost got stuck a few times but that wheelbarrow on the front would lift the front up and I could back it out and a few times I thought about taking the MMM off since it seemed to be a liability instead of an asset. (Years later learned about the plastic fan on BXs that get destroyed so easy so MMM probably saved my fan)
Well, one day I was pushing the trees to gether closer and was working from the upper side of the pile and got the BX2200 MMM FEL up on the pile to far and the MMM got hung up amongst the trees under my tractor and couldn't get it back off the pile. After extensive pondering and numerous attempts I finally gave up. The dozer man was still doing some clean up work for me and my neighbor and his dozer was still in my front yard. He showed up a day or 2 later and I told him to please go get my tractor off of the tree pile and with a grin he left and later I was able to drive it back to my storage building. He got quite a charge out of doing it for me.

I probably cannot explain it very well but until someone comes on that really can explain it I will give it a shot. here is the setup, you have a heavy load in the bucket, and you go to dump it by pushing the stick to the right (at least on my joystick control) and this powers down the load with the fluid from the pump filling the cap end of the cylinder as fast as it can, However the load itself wants to go down faster due to gravity on the heavy load. The pump cannot provide fluid at the rate needed to fill the cylinder and a void develops in the cylinder. now remember when you are filling the cap end of the cylinder fluid is being pushed out of the rod end of the cylinder back to tank. Well there is a further over to the right (at least on my valve) past a detent that is called regeneration. This position takes some of that fluid that would be going to the tank and puts it in with the fluid coming from the pump to fill the cap end faster to prevent the void from forming in the cap end, and this allows gravity to pull the bucket into a dump position faster. I probably did not explain this very well, but the idea is that regen position will allow a faster dump of a loaded bucket.

I always wondered why it did that!!:confused2:

I agree that back seem to work much better. In my old age I have learned to leave the tractor parked when it is wet!!!!:thumbsup:

My tractor has a regen, I guess it works like kevins 3940 does. I will have to play with it to see.

So....................how does it work????

Kevin - Just curious. When you got stuck did you shift your L3940 into low gear, engage 4-wheel drive, and hold down the rear differential lock?

When I first bought my L3940/HTSC I was amazed how little low-end grunt it had in Mid and High gear range, but found it could almost climb a tree in Low, especially in 4-wheel drive with Diff Lock engaged.

I do most everything in mid range & I have not had it stuck!

If you are working it be sure to pull the throttle all the back, you need all the hydraulics you can get, do not baby it.

You do know there is high & low in each range don't you?
