Hydrostatic vs hydraulic shutle transmission

[870wing]

I've been reading a lot of the threads and everyone seems to be suggesting to go with HST over gear transmissions. What are the positive virtues of each type of transmission. I'll get the ball rolling.

HST
Good for repetative back and forth work like gravel pitt work or loading hay bales.
Good choice for new drivers, especially those use to automatic cars and trucks (not trying to start a flame)
Good choice when varied speed adjustments are required like in tillering or mowing around the garden.

Gear
Good for field work like plowing or discing.
Great for going down steep hills with a large load of hay or logs behind the tractor (motor braking)
Slightly less expensive to repair.

What are your positive observations about each transmission type.

An HST will have better resale value according to many.
Fewer & fewer folks know how to use a clutch, so the demand is so much less for a clutched vehicle, and this will carry over to utility tractors.

For a box blade tractor, the shuttle is a dream.

The HST is also good for going down steep hills with a large load. The HST transmission itself acts as a brake.

I would disagree about the cost to repair. I am not sure that can be proven one way or another. It will also depend somewhat on the operator. A good operator of a gear transmission the clutch will last for decades. A bad operator of a gear transmission the clutch can last a few hours. Clutches are neither cheap or convenient to repair.

Gear transmissions can get away with using the Cheaper hydraulic fluids. Hydro's tend to like the higher quality fluids they are designed for. One less filter to buy/change with a gear machine. (hydrostatic filter)

If your knees are worn out the HST is the way to go. No left leg work with that clutch and no braking needed either. The hydro pedal is usually worked with ankle or just a toe.

Hydro's are great for any kind of precision work.. like using pallet forks to put a big load in your $50,000 pickup truck.. You have so much better control of creeping speeds. Don't believe it? look here:

I defy anyone to do that with any kind of gear transmission.

I like the fact that I can give my hst a lot of rpm's and still just creep, in either direction, like in the video.

Lots of power, little speed.

For those of you using a pto implement, you can set the motor at pto speed and still go as fast or slow as you want by varying the hst speed with your foot. With a hog/mower on the back, get that blade going the correct speed and infinitely vary your travel speed for the needs of the terrain.

There is something called a creeper gear, will do what you are doing. I put 2400lbs pallets in my $55k truck all the time with a Shuttle, never have had an issue.

True, but how many CUT's have creeper gears? I can't think of any right off. Mostly an option in Utility tractors, like your RX There might be some CUT out there with a creeper range, as soon as you challenge someone to go as slow as I can with a hydro in a gear rig, and someone will come up with one.

 

[Steppenwolfe]

First off, I have never owned an hst tractor. I wouldn't buy one, either. I like gear drive and a shuttle shift. But, I am also set in my ways, and like what I like. I don't understand the argument of one is easier, better, or worth more. I guess each has its place, and it should be up to each individual to choose.

 

[murphy1244]

These type of threads never end up well. Its mostly a personal choice.

 

[DK35vince]

Its a personal preference thing.
Myself, I would probably lean toward the hydraulic shuttle.
