hydrostat vs gear hp loss

[Soundguy]

Yep.. I mow a reasonable flat open pasture.. I set my range and gear when i pull into the pasture, and I don't hit the clutch till I am pulling out of the pasture. I stay in 5th gear the entire mowing session.. probably 6.5 mph.

I'd have a hard time believing that you can improve on that unless the pasture was as flat as glass and had no tall weeds and there were no ruts to bounce you. In other words.. given identical conditions.. a HST tranny would not improve my time 1% ( should be the same.. etc.. )

That's what the Bride said a few days ago

Yes, I agree that a gear driven unit will put more power on the ground than a hydro, no denying this, it's a fact. When you get down to the blood and guts, it's traction that critical. No doubt your geared CUT will spin the tires if demanded, so will my hydro.

In my opinion (which i am told occasionally has a limited value) a hydro should accomplish the same work as a geared, as ultimately it will come down to traction. A hydro will give up some speed compared to a geared when the drawbar hp max's out. However again, IMO and situation, I believe I can ultimately do more work faster because I change directions at will and accelerate the ground speed when the load on the engine allows. Maybe with the new powershifts and reversers on geared trannys this is not as big a deal as it once was. I'm an old throwback to when gears were just that, gears. And I gotta admit, I love push and go, lift and stop.

I've stalled out plenty of tractors when they are getting great traction and just didn't have the HP to put a mass in motion. The reality is more drawbar HP allows the tractor to run a lot more efficiently with heavier loads.

NewToy[/left]]I have a hard time believing that a hydro unit will give you a 74% efficiency increase in tilling applications and almost 50% mowing. Must be a magic tractor or the person operating the gear unit was completely inept.

So do I. I just said it was interesting reading. Now it's up to you to find out the truth.

Sounds like the old story about making the results come out the way you want them. It was an interesting reading the all articles.

I tried to contact Mr. Corbett but he was down in Talladega trying to qualify that tractor of his.

School should be starting back this week or next so give him another try.

Jerry, is there something wrong with your signature or is it my computer?

 

[NewToy]

BillyP, Your signature line doesn't come up on my computer. There is just a little box with a red "x" in there.

Thanks John, I did had one before the site upgrade. The funny thing is, I don't even see that red x

Billy, It's not your computer. It's this new software. I can't get it to work no matter what I do. I worked on it a couple of times and finely just gave up. I wish someone would tell me how to fix it.

Yep BillyP yours is the typical box with a red X while Jerrys is simply a address to a link (picture I suppose)

Let's see if this works.

Still the red x Billy.

I can't get the image thing to work so I guess my name will have to do.

Red X in the box is gone

The day I was at the dealer to actually buy a tractor the sales rep. happened to be at the dealer also.I got to talk with him a few minutes and discussed this very issue as I wanted a hydro . He asked what I would be using the tractor for,{Tillage work,hauling a few logs out of the woods etc. etc.}he said I would be unhappy with a hydrostat , and said to rethink what I wanted and gave another suggestion.I bought a tractor with a hydraulic shuttle shift and creeper gears and I am very happy with it.I think it all depends on what you will be using the tractor for , depends on what is right for you.I think if one were to really research this issue there maybe a little more to it than just a little drawbar HP loss if one was really working a tractor hard for long periods of time,fuel costs, service intervals and costs,etc., as for us hobby type tractor owners it probably doesn't matter all that much. If you are a farmer trying to make a living every penny counts and is accounted for.I have a hydro on my lawntractor and love it.You have had the gst so I imagine you have your heart set on a hydro as I did.
Good Luck with whatever you choose.

Sorry.. that's a trade secret!

Thanks RaT

Now could someone tell me if my name shows up aa a signature?

Thanks RaT

I assume you mean't as a signature.. Yes it does!

assue​

you meant as a signature.. Yes it does!

Dang it! Yes, as

Thanks
