Comparison HST vs. Shuttle

[Redsox19]

I'm looking at getting a CUT and haven't seen much comparison on HST vs Shuttle. I'll mostly be using the FEL for odd projects, landscaping etc. Is there a huge advantage to either or is it not a big deal?

From what I have read HST has the edge for FEL work.

I have a GST and am trying to trade it in for an HST.

HST is a little better on slopes.

If you're doing repetitive front loader work, HST has an edge.

Since we're talking about CUTs here, most of them have a mechanical shuttle in which case, the HST equipped models will have more than an edge. Hst will be the cat's meow compared to using a clutch all day.

I think someone put it well when they said that if you have to ask what kind of transmission you need, you need a hydro. Unless you've done the research and KNOW that gears is what you want, go HST.

Additionally remember HST takes considerably more HP. In the same chassis tractor plan on a 10hp loss with HST.

If this said "10 percent", instead of "10 hp", I'd agree. A 30 hp HST tractor isn't losing 10 hp to the HST drive, and a 30 hp gear tractor isn't getting 50% better fuel economy than its HST counterpart.

It's usually around 2-4 hp no where near 10 hp. Maybe that much when you get well above 100 hp tho.

I run half a dozen lawn mowers to keep my very diverse small farm manicured. All are hydros and wouldn't have it any other way.

My tractors are all tranny shift except the 6530 which is tranny shift plus shuttle. Wouldn't have it any other way. If I were running a feedlot or such that I see folks in the Northern climates running with the stop and go, maneuvering in and out and all chores, then I'd have a hydro tractor; wouldn't have it any other way.
