What would be some advantages/disadvantages of these two transmissions? Are there any pulling differences? Seems to me that the gear drive would give a more steady pull vs trying to maintain a steady throttle with your foot on the HST.
Absolutely agree. Just because one or the other works for someone else doesn't mean it will work for you.Go drive both around the lot and buy the one 'you' like best.
I know what you're saying, and also realize you said it was only your experience. However, I think it's misleading to compare a machine that is out of acceptable specifications up as an example of why not to buy a particular type of transmission. I'm confident that no manufacturer's service manual allows for the tractor to drive forward when everything is at rest....Both... are HST drive...and when you let off the pedal it would creep and bump into the side of the truck...
Using a friends John Deere skid steer...his skid steer would creep forward unless you set the parking break. (sp)
Very good points and pretty much what I would say only maybe not so well. If I judged gear tractors by some of the junk with which I had to farm with I wouldn't go near one sae with some old worn out HST models.I know what you're saying, and also realize you said it was only your experience.

That doesn't mean the fine-tuning maintenance issues aren't an issue, but I think that should be the focus, not that an HST will drive around on its own and be hazardous. I've had two of my straight gear tractors get the clutch plates bound together after sitting for awhile, and it is startling and dangerous to have the clutch depressed with the tractor still backing up toward something valuable, and the clutch pedal have no effect.
The additional importance of properly adjusting the HST pedal and valve is, in my view, a valid and important maintenance concern, but adjusting the slack in the clutch pedal and ensuring the tractor is in neutral when starting are crucially important, too.
I'm not trying to cause an argument, and I generally like gear drive machines more (I don't even own an HST compact tractor out of my dozen or so machines), I just don't think that experiences with worn-out and/or improperly maintained equipment by themselves are convincing arguments against selecting an HST over a gear machine. We would complain in a similar fashion if someone said "A gear tractor has a clutch, and if you try to use the clutch to control your speed too much, it will wear out, and then your tractor won't move at all." While true, it's not really applicable when the equipment is properly used and maintained.
Otherwise, I agree with MtnViewRanch. For doing mowing work, loader work, moving trailers, or other things where the common sequence of events is optimized by the ability to quickly change direction or speed, I think an HST is undoubtedly superior to a gear drive machine.
Mowing is really a LOT easier when one can increase speed through light sections, or straightaways, and then instantly slow to inching speed, for tighter areas or thick, hard cutting, all while maintaining PTO RPM and power. A gear tractor is obnoxious in comparison, either requiring constant stop and start shifting, or running at sub-optimal PTO RPM.
I have used HST machines, and have actually gone back to using all gear tractors, but for some applications, HST's advantages outweigh gear tractor's strengths. In some cases the opposite is true as well, and then there can be ergonomic issues: I get soreness in my ankle and lower leg from the constant feathering of an HST; this may be the particular machines I have used in combination with my own physical quirks, but my gear tractor's clutch pedals never give me issues. I've also not heard many people complaining about pain from the HST pedals. I don't know. The cruise control featured on newer machines may alleviate many of those particular gripes I have.
Whatever you choose, share pictures with us, and let us know how it works for you!
Lots of variations, so you have to get the one that works for you, kind of like the old joke, Patient, "Doc it hurts when I do this." Doc, "Don't do that."I'm not sure if I've said this in any of these debates. I don't feel there is anything wrong with HST trans, it's just that I Don't like them and I do not want one.
On a side note. My mom hurt her back using a small Massey Ferguson with HST. The constant strain of pushing the peddle down really messed up her lower back. She is no longer allowed on a tractor. I will say the HST peddle on this Massey is hard to press and puts the right leg/hip/lower back in a very uncomfortable position. Cruse control never worked well either and she didn't like using it.
Maybe if she had of bought a Kubota instead all would be good?
See, it works for me. I'm not discounting what you are saying- not everybody likes the same thing. But, I use a finish mower behind my 7100, and half of my mowing is done backing up- I back up, turned to the side, watching the mower, very often (mountain land, not many long runs). I don't have any issue operating the HST pedal. I pushed a lot of snow this past winter, with the backblade turned backwards- it moved snow better that way. I cleared half or more of our church parking lot turned sideways, and it wasn't a problem. So, for me, it's a none issue. Now, if I had to be turned sideways and be hitting the brake while throwing in the clutch, that would have been more fatiquing. Not difficult or impossible, but fatiguing.Another key point for me, like I was describing to a new member the other day who was saying their back was killing them from twisting in the seat to look at the grading box behind them. I've learend to sit cock-eyed in the seat with my butt cheeks twisted at the bottom so it put less stain on my back when looking behind me. In doing so when I'm involved with a lot of grading and backflling my legs don't end up in a normal position and I doubt I could work the HST pedal being seated that way.
