Hydro vs Standard Shift?

Well said, Doc. I shouldn't have made a blanket statement about all HSTs, just given the facts of the two machines that I know about.

After reading this thread about the HST, I don't believe I would want one. I think Yanmar's "powershift" trans. beats the pants off it in every respect. It is gear drive, but you can shift without the clutch, forward and reverse, It has both hand and foot throttle so you can set your speed or vary it as you choose. There are a few extra parts and springs and stuff to allow it to shift, but nothing any shadetree mechanic can't handle.

The reason it gives the rpm at 2000 up is because of it being a gas engine. They have to have higher rpms to have power. Now a diesel gets its power at a much lower rpm, so you could run it at a lower rpm and still have the power. I am a Yanmar owner and like my gear trans. but at the same time, a fact is a fact.

I stand corrected Richard, as usual, you are right and I am wrong. Your calm demeanor has prevailed yet again. I should have said: No where, zip, zero, nada does my manual say anything regarding the HST and the RPM associated for it to be run at. Perhaps then it is a Kubota thing. It works extremely well at the lower RPM's. You can very easily use the HST at any RPM, much like you can run your loader and associated hydraulics at any speed. The higher the RPM, the greater the flow.

Now, ARE THERE ANY OWNERS OUT THERE THAT HAVE TO RUN THEIR HST AT FULL THROTTLE? If you do, please state the brand. I'd like to get to the bottom, you know, to see if there is a concensus.

Now was that necessary? /forums/images/graemlins/grin.gif

Moss, I think the Cowboy was shooting that zinger at me. You are quite correct and now we have two brands that don't demand full throttle to operate the HST.

MossRoad - Don't forget picking up the garbage can with the fel without knocking it over /forums/images/graemlins/grin.gif That would make a great timed event and no need to get a stop watch. I could just use the hour meter on my tractor /forums/images/graemlins/laugh.gif

I sure dont operate my hydro at full throttle and my hydro is not any louder than any other tractor of the same size..

Jeeze - am I late juming in here or what! /forums/images/graemlins/grin.gif

I only use the higher RPM ranges on my L3130 HST when I'm doing heavy work. I have not read anything in the manual that tells me otherwise - but then again I haven't read the whole manual. So for now I'll plead ignorance and say that it seems to me the HST functions well in any RPM range.

I will note that I haven't been playing in this "game" for very long, but it sure seems like the gear vs. HST issue comes up a lot. And it NEVER gets resolved - most likely because the only correct answer is not to play the game. Kinda like Thermal Nuclear War. /forums/images/graemlins/cool.gif

I'd like to add something that many of us (including me!) seem to forget at times. Many of us base our opinions on the tractors we own and they all have different maintenance and use histories. While I may offer my opionion on my 2001 TC40 someone else my offer their opinion on their 1985 (insert model here). I'm sure we can all agree that times and technology are constantly changing and what a manufacture recommends for a 2003 model hydro won't be the same as what was recommended for a 1985 model.

For example: machining tolerances are much tighter now for engines and lubrication specs have changed dramatically. 30 years ago I'd never dream of running a 5-30 multigrade oil in my 350 chevy, but 10-30 now seems to be the norm. I also know a lot of folks that have vehicles with high mileage that are spec'd to run 10-30, but they're running heavier oils to account for engine wear. Another example is seal and pump wear. Two identical hydro tractors with one with 100 hours and one with 1000 hours may actually function best at different engine rpm. The tractor with 1000 hours will likely need to be run a little faster to account for seal and pump wear to operate at the same capacity as the one with 100 hours.

I guess the point I'm trying to make is there really are no right or wrong answers in discussions like this. We're all working with different equipment under different conditions and what works for me won't necessarily work for someone else.
