Tractor Sizing Highest HP HST Kubota?

[SDT]

Thank you, SDT. You know - one of these days I might even understand all these types. I come from the era where transmissions were either manual or automatic. H e l l - I come from the era where ALL transmissions were manual. I think the first auto tranny I ever saw/heard of was in the brand new Buick the local banker purchased.

The Buick Dynaflow, through very inefficient, was probably the first readily available automotive CVT sold in the US.

Google dynaflow for more information

The first automatic I saw was the neighbor's 1951 Chevy, I didn't believe there was a car without a clutch pedal till he showed it to me. The first automatic I rode in was a '53 Pontiac and I watched the shift lever to see when it changed gears and it never moved, I thougt it was really weird.

. 700hp dozers have HSTs, so it's not a matter of engineering or capability. Just a matter of efficiency, control & price for the target market.

True. You would think that manufacturers would make a 100-120 hp model HST. The state guys who use the long arm boom mowers to cut right of ways im sure would love to have the ease of a HST while creeping along and making multiple stops and backing up.

The only thing a small tractor with a hydro has in common with a 700hp dozer with a hydro, is the name!!

I’ve never had the displeasure to tear down a 700 hp dozer, but other than the size what’s the difference in the basic concept? I bet the dozer still has a hydraulic pump or pumps that powers a hydraulic motor or motors with a gear box behind it and probably has better oil cooling ability.

Today in the larger tractors they have several versions simular to the hydro called CVT and they are getting the bugs out of them! Like all hydro's they shine with PTO work and when mounting multi mowers on them they are good up to about 1500 acres a year before they go into the big self propelled machines.

Are you saying AGCO/Fendt is still working to get "the bugs out" of their Vario tranny???

I bet that would be news to them!
