any downside to hst?

[wolc123]

As fuel prices continue to rise, I expect that the popularity of hst and even cabs with AC will decline on CUT's. These features are nice but they absorb a very considerable ammount of power on a CUT and that means greater fuel consumption to do the same job. This might not get too many people's attention now but when diesel reaches $10/gal it might.

Can't pull start a hydro can you ?
My friends 5000 ford battery went out last weekend and if we could not have pull started the tractor the hay would not have been rolled up before the rain came.

As fuel prices continue to rise,....

At fuel consumption levels hovering around 1 gallon per hour, I doubt homeowners will start considering fuel economy. However, business users might.

If you want lots of working power. Go with the geared tractor. If you want comfort and conveinence go with the HST. If you do lots & lots of loader work go with HST. I'm going to put my 10 year old JD 870 (28 hp geared) against my new JD 3520 HST (37 hp) drawbar to drawbar and then FEL to FEL tomorrow and see which one wins. My moneys on the 870!

I think I have to agree with Jerry.

Looking at average tranny repairs on gear units vs hydro units. In many cases we are talking about a 350$ clutch job on the gear unit.

Some of the hydro trannies on a piece of equipment are a single integral assembly.. that whole hunk o' iron has to be changed out to repair in some cases.

In some of our older mid 80's large tractors used to run tillers.. the gear are BY FAR easier to work on... You can drop a tranny, reseal, add bearings and what not in a day.. for a few hundred dollars of soft parts and bearings, and a couple hundred bucks in shop labor... vs sending a hydro unit out to the specialist shop and then praying the repair doesn't cost 25% of what you paid for the machine... plus your shop labor that tore it down and reinstalled it.

Soundguy, Jerry,

I am just an ornery guy and am going to respectfully stick to my guns. The transmissions that Jerry listed are all at least as advanced as an HST, most are much more complex. They don't have gears to press off a main shaft, or a clutch. They have solenoids, valves, valve bodies, seals and planetary gears. Soundguy, I know you will understand this analogy, the bulk of what Jerry listed as "gear" transmissions" have more in common with a Ford SOS transmission than a 4 or 5 speed. I say, "in common", as they are as complex if not more complex than the SOS.

Now don't get me wrong, they are very good and dependable. My point is that you can't create the mindset that the repair cost of a PowerShuttle, PowerShift, DynaQPS and CVT transmission is in the same league as the 4 speed in my old Ford 4000! I seriously doubt there is any real difference to repair the CVT the DynaQPS or the HST.

My sincere hope is that I won't have to find out!!! I do know that the repair of the 4 speed was about a grand, and I did all the work. (Twice, but I won't go into that ...)

Please take a look at the link~ ! It is for the IVT trans that Jerry mentioned. Pretty cool technology. But, is it a "Gear" trans? Anybody think it will be cheap to repair? Personally, cost to repair the trans is a non-issue for me. I bought the one that makes my jobs more efficient, easier and to be honest more fun.

The CVT is the only one of the listed models that is anywhere even in the vicinity of as complex as a Hydro. The DynaQPS is a PowerShuttle with PowerShift that uses solenoids as the most complex part. It has all the parts such as clutches, gears on main shafts etc. The solenoids are the most advanced part of the unit. The other three are even less technical. So there is only one that is even close to a Hydro.

Now don't get me wrong, they are very good and dependable.

John unless I missed something or miss stated it, I didn't even mean to insinuate that the repairs were as simple as a crash box tranny. They are much simpler that the Hydros with maybe the exception of the CVT which could be as expensive.

My sincere hope is that I won't have to find out!!! I do know that the repair of the 4 speed was about a grand, and I did all the work. (Twice, but I won't go into that ...)

Back in the archives, there have been hydros that have been repaired and where the owner posted the cost. The parts alone have been many times that.

I will be glad when they start putting the CVT in 40-50 horsepower tractors. I will be in line to purchase one.

That is what everyone needs to do. Be well informed before purchase and then buy what fits them. I think that this thread has gone to far from its origin. I started posting on this thread to let people know that modern manual transmissions are far far easier to use that what many on this thread would have them believe. It has advanced far past that. THE END.

Jerry,

I do hope that I haven't "rocked the boat" too much and disturbed you. If that has happened, my sincere apologies!

You are indeed correct, gone are the days when you built up a bulging left leg using your tractor! (thank goodness too)

Not at all John. It has been a good discussion. Have a good day.

 

[Soundguy]

Yes, I love wet brakes. They stop much much better, but I agree on them being a lot harder to change. I don't like to change them at all, especially the ones that are next to the transmission case. Thank goodness, they last a very long time.

Yep.. like the ones in the axle trumpets near planetary or final drive sets... Super nice work. Thanks goodness they last longer!

Anyone here ever had to do the "Remember to park on a hill so you can get started in the morning".. issues.. like .. bad starter.. etc..

Been there.. done that.
