dumb question about HST

[phantom309]

Another dumb question about HST:

How do you shift the range selector with no clutch?

Guessing that the answer is just stop and keep your feet off of the Go pedals?

yep, I put just the smallest amount of pressure on the shifter when almost stopped but not under a pulling load or when the engine is providing hold back.

The manuals for my Kubota HST tractors say to throttle back, take your foot off the treddle and come to a near stop before changing gear ranges. I find it's sometimes easier if the tractor is moving slightly.

Gear changes are a lot less frequent with the HST plus transmission, since you can shift on the fly.

I can shift on the fly with my gear drive too, up or down as the gears are synchronized.

I don't understand. Is it really "shift on the fly" if you have to "come to a near stop"?

He is referring to the Hi-Lo in each of 3 ranges, which is shift on the fly. My Kubota HST+ transmission requires a complete stop to shift between the H/M/L ranges.
It's a great transmission, and can also auto shift the Hi-Lo based on load.

You have to stop to change ranges. Helps if you let it roll very very slowly. Applies to either type of transmission, gear or HST.

Now that you mention it, I do remember seeing something, somewhere, about a hi/lo within ranges. Sounds pretty nice.

Most of my reading/looking has been on Branson/TYM tractors. Guessing those do not offer this or I would have read more about it...?

I had another question about HST vs gear, and it hit me to ask Google's AI, since it knows everything:

(text above was highlighted by Google, with more info on each of the four items offered below the above text)

After I read the above, I was thinking that HST is best for lower power applications, but I remembered that I've rented articulated wheel loaders before. They were larger than a utility tractor, and they are HST?!?

I guess that the word "loader" in articulated wheel loader is key. A wheel loader is more focused on a single task than a utility tractor, and that task is 99% back and forth, stop, start, reverse, etc, and that is the area where HST excels.

yeah, I think a lot of CUT work is perfect for HST and HST is perfect for it, while utility tractors tend to be more in the.... tractor.... application, where HST can be a negative and there's little point of having it.
