Gear drive vs hydro

[patrick_g]

Someone (might as well be me) is obligated to point out that with a gear transmission you CAN KNOW your actual ground speed, which can matter for some spreading or spraying tasks.

Funny but I had always thought my speedometer was measuring actual ground speed (hydrostatic tranny) irrespective of my gear range selection (low medium or high), hydrostat pedal position (going forward), or my RPM (as registered by my tachometer.)

In the world of experience there can be empirical observations but very few empirical facts.

george, you guys are jerky,

i remember once i called u and a few knuckkelheads, and you pointed out that you didn't know how to respond to somebody that can't spell knuckel...
we been callin evebody 'nukeheads' since...

ps i cant be here now since i have to do the 'pandora radio addiction thing...'

The loss of HP can be confusing.

You've got that right, but it is more confusing than what you've just explained.

As you say, there is some loss of HP at the PTO, but not much.

There is no (or trivial) loss of HP at the engine.

But I would assume that engine HP is measured at the flywheel or some point shy of where the wheels contact the ground, which is where it matters and what we never get specs on.

I'd guess, but might be wrong, that given the same engine HP a geared tractor is going to transfer more of that HP to the ground than an HST.

So if I'm right, its not just a simple matter of what your PTO has to turn.

But finally, as it has been stated so many times, the real issue for the vast number of us who do not have unlimited incomes is not how much HST skims HP from any given machine, but how much more HP you can BUY with a geared vs a hydro tractor.

Yup; nothing like a little time spent using a system before you speak volumes about it. Next thing one knows the common man may start preforming operations of some sort!

There is a degree of accountability is there not; be it professional or not?

Pat;some disinformation on ground speed as shown by the dash indicators. I believe the optimum traction is delivered at with approximately 10% ?? slippage of the driving wheels. An indication that perhaps a GPS system may be more accurate.

george, you guys are jerky,

I've been called worse, even by people who recognize sarcasm.

i remember once i called u and a few knuckkelheads, and you pointed out that you didn't know how to respond to somebody that can't spell knuckel...

I don't remember that.....but I'm sure its gotten lost in the countless times I've been called knucklehead....today.

we been callin evebody 'nukeheads' since...

Well, I think that is something altogether different different from a knucklehead, and I don't think I mind being called a nukehead at all.

I think it is great that we are multilingual here at TBN.

The question I answered asked about PTO HP, not power to the ground.

Maybe, but I hardly need to hit myself in the thumb with a hammer to know that it hurts.

Next thing one knows the common man may start preforming operations of some sort!

I think very common folks perform all sorts of operations all the time.

There is a degree of accountability is there not; be it professional or not?

You've thoroughly lost me......and it feels kinda nice.

Pat;some disinformation on ground speed as shown by the dash indicators. I believe the optimum traction is delivered at with approximately 10% ?? slippage of the driving wheels. An indication that perhaps a GPS system may be more accurate.

I would think simple experience would suffice, no?

Hey, where is the speedometer take off on a tractor, anyhow? I don't have a speedometer on my little PT425 and I don't believe my old IH had one, either.

So what is the typical HP difference, something like a couple percent at most???

I'd gladly trade off a couple percent for the distinct advantages of HST.

I fail to see the implied importance of the difference.

...and Egon, what has reality to do with much of this discussion? Limiting the exchange to only those with reasonable experience on both geared and HST tractors would eliminate so much colorful opinion-expression based on (well based on ... hmm well it would eliminate a lot of baseless opinions) and reduce the entertainment index of the thread.

It sure would when one when one is pontificating.

Otherwise one may become confused by the pontifications and actually come under the delusions that confusions from improper pontifications were actually empirical observations of the delusional variety.

May whatever Deity in fashion have mercy on the patients.
