HST vs. Gear Drive

[N80]

Chris, you did contradict yourself on this one. You listed the gear as more durable, yet you personally have seen clutches burned up in 30 minutes! And the exact word used was "reliable", not durable.

John, I gotta disagree on that oneand think you are distorting Chris's point. There is a world of difference between someone destroying something and its durability or reliability. I personally don't think reliability or even durability are a function of abuse, stupidity or negligence. An HST might be easier for a novice to use without damage but that hardly makes the mechanics of it more durable in regard to what it was designed for. And it seems pretty clear that someone who could do what Chris described could probably also make short work of an HST as well. One could argue that the HST is made to take the abuse of the ignorant better than a manual, and I'd concede that point, but not that HST is more durable than manuals on the whole.

porsche has been offering their Tiptronic transmission (no manual clutch) in the 911 for a while..and at least in 07, maybe before the "automatic" is faster than the "manual." It shifts so fast that the turbo(s) stay under load so there is less power loss. This year it has been futher refined..and still faster than manual...read up on it at Porsche...

"Porsche developed this gearshift principle for racing no less than 25 years ago. It features two parallel clutches to eliminate any interruption in power delivery and eliminates even the slightest break between gears. Porsche factory drivers benefiting from this technology were able to accelerate faster than their competitors and keep both hands on the wheel while shifting gears, thus avoiding even the slightest distraction. This pioneering achievement from Porsche’s racing efforts now gives the new 911 Carrera and Carrera S even better performance. The Carrera equipped with PDK covers 0-60 mph in 4.5 seconds and the Carrera S reaches the same speed in 4.3 which is 0.2 seconds faster than with a manual six-speed gearbox."

I saw that. I just wonder why they don't offer it on the fastest and most expensive one (the GT2)? There must be some folks with a lot of money that remain happy with a manual gear box. They're probably the type that are all show and no go.

probably, and if you are payin that much you can have whatever your heart desires. for me, an automatic car for the wife with the allowance of a no clutch manual gearbox for me and my HST 3320..

No contradiction there.... unless you have a narrow 'head in the sand' type of view..

Anyone can damage any equipment if used wrong. I can take a die grinder to a brand new anvil and ruin it in a few minutes.. even if it was a real good anvil.

I'd wager that same operator that can burn up a clutch in a gear tractor in a short time period could do some good damage to that HST tractor too.. I imagine constant relief valve passing oil would probably make something mad after a few hours..

Hi! Kubota HST are very good and are the best for FEL works. BUT HST tractor take more fuel for make the same work. BECAUSE with variable hydro pump-valve and control to hydro motor drive you have lost 5 to 10% WHEN NEW. So With A Very used Hydro-tranny the lost can to go to 20%. A very used Hydro pump lost oil pressure and deliver less power at Hydro motor drive. With Gears and good clutch The lost about 2% do not change New or used.
On very used tractor I prefer Gear Less expensive to repair. Thanks and Good luck! Oldmech

hey now.. don't be trying to confuse this opinion based issue with facts now.. you hear...

Yep, and that's what it usually boils down to, personal preference. I love a manual transmission. I like feeling in control. I like having the vehicle do exactly what I want it to do, when I want it to and how I want it to and not what it thinks I want it to. I'm only just now warming up to antilock brakes and I don't give a nit for traction control even though my wife loves it on her car with CVT and all wheel drive. Makes her feel very safe and secure in rain and the occasional snow.

I've always been someone who enjoyed the act of driving (preferrably off road) and not just being driven. So the appeal of automatics and HSTs has always been lost on me. My Ford F150 is a fine vehicle and performs its tasks well but I don't look forward to driving it because it is an automatic with no manual available. I think it is sad that you can't find many manual vehicles anymore and that if you want something that approximates the control of a simple 5 or 6 speed manual gearbox you have to pay for an expensive, complicated, computer controlled thing. I think it is great that Porsche gives you the choice. I wish this extended to basic trucks and cars.


I'm now driving that 8 year old Maxima. My son will take it to school in a few years but until then I'm driving it mainly to save gas over the F150. But the thing is, I enjoy driving it. Look forward to driving to work! The manual is fun and of course the 2000 Maxima is bland looking car with quite a bit of power and excellent handling (accoroding to all the car rags anyway). I love puching the accelerator and not having to wait for the torque converter to lock up!

I also love the precision with which I can operate my L4400 using the clutch. There might be a learing curve, but to me, its worth it.

Nice thing is, there's something for everyone.

And there are still plenty of folks out there that will tell you that an LP has better sound than a CD when all the tech data says otherwise.

And hey; you gotta remember that if the system fails on a railway track you can always drive it off if you have a geared transmission.

Of course there are not too many four speed geared transmissions around in newish tractors anymore! Wonder why? Have the manufacturing companies pulled their head from the sand?? Or???

You also gotta remember anything else than a three or four speed straight geared tractor transmission has not stood up to the test of time!

Maybee in your frozen little town?!?

The 'ford' tranny in my NH 7610s is a 4spd with a hi/lo range shifter. it's essentially the same tranny back from 1965... That ford tranny was one of the more robust designs ford came out with.. a tough old crashbox. Virtually identical trans in my ford 5000 as that 7610s..

Nothing other than 3/4 spds have stood up? Guess all those still running 5 and 8 spd in fords don't exist then right? I got 3 nice shifting 5spds in my barn..
