HST Transmission

[Libertine]

Tractors4u:

Been accused of posting too many "depressing" subjects. Thought I would go the other way.

I'm not sure I follow you on the dragging a heavy object up a hill. My tractor with HST (I have a manual, a shuttle and a HST tractor) would only creep ever so little if the engine quit. That coupled with 4WD which the brakes would effectively lock all 4 wheels to the ground would eliminate any of those concerns, but it could also be that I'm missing something here.

Most folks here are enthutiastic about Arnold. Yesterday at his first budget/press interviews he did what most considered to be a superb job of answering the media questions. The answers were very non politician like and that was alone inspiring. He even got politically incorrect and mentioned sitting down and smoking cigars with others to discuss the options. Wow, publicly saying he would smoke a cigar. Pretty Cool!

That is one of the reason that I bought a power shuttle. I do a LOT of composting in tight quarters. I can put it in a slower gear and just keep going by flipping the lever back and forth, without wearing a standard clutch. The fluid immersed clutches will wears a lot longer than than regular clutches.

I would have to agree with Rat here. What are the safety issues with Hydro. If my tractor quits is does hold pretty good for a while. Plenty of time to get my foot on the brakes. I just reach over put in neutral and restart, shift to lower gear and go. If a manual stops on a hill it will start going back down even in a mid range gear. The only way it wouldn't is if it was in the lower gears which it shouldn't have quit anyway in the lower gear. On a manual as soon as one pushes in the clutch to start you are rolling unless you have your foot on the brake pretty good of course, but once running then you have to let the clutch out while holding the brakes and a lot of people do have trouble with that, especially people that don't have a lot of experience. I guess again my question is, Where does the safety issue come from. I hate standard transmissions, always have and always will and Hydro is for me not for any safety issue but just from the ease of use. Gee a lot of manual rigs out there keep going when you fall off the seat and if you even got a seat safety switch just the motor running itself down keeps itself going enough to do harm. Hydro would stop immediately in my case at least.

just my two cents.

thcri,
A manual on a tractor is not like a manual in a car or truck. If you was to stop on a steep hill, you don't have to give it the fuel as you let off of the clutch. You put it in the right gear and then let the clutch out. It will go without worrying about the fuel and feathering the clutch. And yes, you do have to have it in the right gear.
Talking manual and hydro transmissions on TBN should be classified as politics. /forums/images/graemlins/grin.gif

I have stalled mine on 25% grades and never had one roll fast,it will move some but not fast enough you do not have time to get your foot on the brake or set the parking brake if needed or drop the blade/loader.Have a gear tractor stall on a hill you have to either put it in neutral and or engage the clutch and start it again,I think you have more of a chance of it rolling with the clutch in on a gear tractor if you do not get your foot on the break quick enough. I have had my foot slip off the clutch on a hillside and cause the tractor to "pop a wheely" if you are not careful.

Jerry,

I guess I would agree with that. But you still have to push the clutch in to even start most standard tractors. My question to the whole thing is where does the safety issue come in that is more on a Hydro than a Clutch. To me the Hydro definantly is not more dangerous. And yes it is politics am I am not questioning anybody having one or the other. Some people like standard transmission and that is great and fine with me. I just would like someone to point out to me as one previous poster said that hydro is more dangerous, where??????

I'm a gear type guy myself and with my JD 990 you don't need to press in the clutch in to start it and I don't. I only press the clutch in to start older tractors at work just be be on the safe side. Some may not have working neutral start switches and most are pretty big tractors so it's best to be extra careful. Once when I was real young with my grandpa's JD 214 garden tractor it slipped out of 3rd gear and my feet were not long enough to reach the clutch and brake at the same time and I almost lost control going down the hill in reverse. Now if I am on hills with a real tractor I give it a little gas with the hand throttle and it goes up pretty easy. I don't find hydros to be any more dangerous than a manual. I think if people are just more careful of what they are doing and not listening to the radio headphones while operating equipment more accidents could be prevented.

Murph,
I didn't have anything to say about the safety thing. I am one of the ones that just like a standard as in shuttles. I have drove hydro's and I just don't like them period. If someone does that is fine with me, they can have them. What I can't understand is how defensive some people get about those of us that do like standards. I don't like hydros, don't have any use for them and don't like the way they sound, operate or anything else, but I don't hold it against anyone that does like them or try to make them look stupid because they do.

 

[thcri]

No Jerry you didn't say, it was a previous poster that said they were dangerous. And I just don't see where they are dangerous any more than the standard. When it really comes down to it most accidents happen because the operator wasn't doing the right thing. He was doing something unsafe. And Hydro is no more unsafe than standard. I appreciate the fact that you like standard. There is nothing wrong with them, I believe that is a personal preference.
