Scotty please explain what you mean here because Deere does make a medium size TLB in both the 3E and 3R tractors and the Deere HST's are probably the best in the business.
hmmm. I'm not aware of any small TLBs that are currently being made by JD. Up until 2012 they used to make the JD110TLB. It was a nice machine although with some problems. John Deere discontinued it instead of improving it. Kubota went the other route with their TLBs. They are now on 2nd generation TLBs.
I think you might be confused on Tractors vs TLBs. In that you have good company. What happened is about 4 or 5 years ago some dealers started calling their tractors equipped with a an add-on loader and an add-on backhoe implement as TLBs. But that's just sales hyperbole.
A TLB is different from a tractor. They are generally a little shorter, much more heavily built, have a more powerful loader and hoe, & weigh almost twice as much. They also cost substantially more than a tractor with implements.
TLBs are designed from the ground up for the stress of a loader & backhoe It's true that on some TLBs the backhoe can be removed and replaced with a 3pt hitch. Puttin on a 3pt makes a TLB into a sort of tractor, but without the long wheelbase and weight distribution that makes a tractor nice for working all day in the field.
A TLB is better for back and forth dirt moving work.
TLBs are squat, wide, heavy, and powerful. And to me they are also less comfortable than a tractor
Both can do either, of course. But both are specialized.
Or look at it this way... A tractor is built to pull things. Sure you can add a loader and a backhoe as accessories to a tractor but that isn't the whole story.
A TLB is built to lift and dig. The loader doesn't come off, and on many of them the backhoe doesn't come off either.
So the basic machine starts as either a tractor or a TLB. Either can mount attachments so that it can do some of the other ones' jobs, but putting a 3pt onto a TLB doesn't make it tractor, and putting a loader and backhoe onto a tractor doesn't make it a TLB. Different from the frame up.
For an example of what I mean, compare the old JD110 with the JD 3E & 3R. Look at the machine weight & FEL lifting capacity.
Or for a better comparison on today's market, look at the Kubota
M6060 Tractor and compare with Kubotas
M62 TLB.
The Tractor weighs 5400 lbs, the TLB right at 9000.
Physically the TLB is a little smaller than the Tractor, but it can lift substantially more. They are built differently for different primary purposes.
This isn't Kubota vs. the world. I love those JD110 TLBs. Google them and have a look.
Fact is, we were going to buy the JD110 back in 2007, but it was having problems right when the Kubota TLB came out.
Sure wish JD had kept making the 110 though.
Oh, on your other question about the HST tranny. I'm curious what makes you say that JD HST are the best in the business? Is that factual or a bias?
I think JD HST are fine myself, but don't know enough about HST in general to say that one is better than another. But lets assume just for argument that JD and Kubota HST are equally durable.
Kubota offers a fingertip range splitter on some of their HST transmissions - and nobody else does. Kubota calls it the HST+ version & it gives the operator a choice of 6 ranges in forward and reverse. That makes Kubota's HST a lot more efficient, and is part of why I said that Kubota was leaving the rest of the HST world behind.
The other reasons have to do with operator-adjustable features of their HST+. Things like adjustable attack rate and throttle-to-load rpm matching that are part of Kubota's HST+ package.
Go try one. It's called HST+, and it is not earth-shaking new technology. Evolution, not revolution. But nobody else offers those features for their HST transmission. That's all it is. I imagine others will someday and maybe even better, but right now Kubota is leaving them behind. HST+ sure works well.
