Gear drive vs hydro

[mike194]

sounds like a hydro would just give everyone more time to go home and argue on the internet.

 

[jake98]

can't argue with that...

ps did we really let anybody name a place 'north east south' anything? sounds like you're trying to confuse the cityfolk or somthin...

Don't think a gear drive is stronger. All the power is transferred through the same weak stub axles which do break.
The hydrostat might be far better for insurance against breakage.

Axles on tractors do not break from torque loads. They break from bend loading caused by side loads on tractor or excessive outward offset to widen stance. This is a design deficiency pure and simple if it happens in normal use parameters of the tractor. Breakage of the axle from a torque load would only happen in the case of manufacturing defect or negligent design.

I agree...and thanks for the help.

 

[MossRoad]

depends on the tractor.. some have them off the engine.. some off of a pump.. some off of the alternator.. As you can guess those are usually tach's with a ground speed chart.. or ring on the tach to show ground speed in a gear, at a specific rpm.. etc.

sounduy

Thanks! So there's a chart around the edge of the tach with different rings for different gears for different RPMS? Anyone got a picture of that. Sounds interesting.

I love seat time like the next guy.. but more free time was what prompted me to trade in a nice 33hp 4wd with 12x4 tranny for a plain 95hp 2wd 8spd. cut mowing time from 6hrs to about 2 hrs.. the 12000$ that 'deal' cost me was well worth the time I gained from not spending an extra 4 hrs per mowing cycle away from other things i needed to do. Here in florida.. mowing cycles can be as often as every 5 days if we are getting proper rain and temps are'nt totally blistering..

You and I have had this discussion before... you actually do real work with your machines and most of these folks do not.

Give me a break. What loader intensive jobs do you have on a daily basis with a tiny tractor that the pounds loaded/minute advantage of HST has a measurable impact on your family life? And while you may fire back some justification for that, and it might even be real and rational, that certainly won't be the case for 99.999% of us who also own tiny little tractors and spend more time arguing about their transmissions than using them. Right?

Wrong!

I've spent many hours doing maintenance on ball diamonds, mowing, brush hogging, snow plowing and moving material from point A to point B. Massive amounts of material. Truck load after truck load of moon dust (granulated limestone) on ball diamonds each year. They are not daily chores, but weekly, monthly and seasonal chores.

I spent 6 years working at the airport. Part of my duties was grounds keeper. Many hours on gear tractors and gear forklifts. I'm here to tell you that ANY job that requires multiple changes in speed and direction are easier on the operator and faster done on a hydrostatic transmission than a gear transmission. Jobs that require brute force to the ground like plowing dirt, or mowing vast expanses of acreage as Soundguy does are better accomplished with the gear.

Yes, you will get more HP for your money with a gear tractor. But there comes a point where more HP is useless, like mowing a half an acre lawn with a 90 HP tractor and a 15' batwing mower.

Get out there and put some machines through their paces. That's the only way you can become a witness. Everything you say about an HST is hearsay. Book smart Vs actual, real life experience.

As per the rules of the drinking game... I am now schnockerred!!!

 

[jake98]

****, did i start on the wrong day?? i already drank myself sober.

Mossroad,

If it was up to N80 I would be mowing turf accounts, moving pallets, lots of loader work on concrete, gravel, & dirt, bushhogging, and rarely if ever operating in mud using a gear tractor with R1 tires.

Oh no, did I just introduce the R1 vs R4 saga into this thread as well.........

 

[jake98]

You and I have had this discussion before... you actually do ""real work"" with your machines and most of these folks do not.

I put double quotes around a healthy pet peeeve. what is real work, a fisherman would think it's another typo. Personally I think everything I do is on the real side. (other than typing gibberish late at nite here), that's just plain fun.

this is supposed to be about gear/hydro not how much can sombody afford or how far can i puff out my chest...

nobody answered yet if they have syncro on a CUT...

jake

what's up? you guys all trying out pandora.com? i can't hear you...

 

[SPYDERLK]

L2550, L3450 dont grind too much up or down -- close enuf. 7520 has it but will grind if you go down multiple gears in one step - can go f/r shuttle w/o stop. BX1500 grinds when shifting ranges if tractor is moving much. JD has synchro in each range - f/r in range w/o stop.

Larry,

So you're saying yes? We can buy compact tractors and drive like Mario Andretti?
I didn't know syncro was an option on a CUT. Probably a good thing.

-It may not be. The Kubs dont have it near as I can tell, but they dont grind ominously. The Mahindra doesnt sound or feel as harmless when it grinds so lucky its seldom due the synchro. I wont worry so much down the road after the edges of the teeth have gotten radiused by a lot of little grinds. Difficult to explain the distinction between ominous and practically harmless. Its an experience/feel sort of thing.

 

[jake98]

that's funny but i don't know w hat you're saying.. other than the grinding

are you guys doing the game tonight??? not funny to not invite me on the right nite.

That's the way my B-I-L's John Deeres are. They are older tractors though. I think, but don't remember for sure, that his Case-O-Matics have the same thing. Nice feature and seems like it ought to be included on pretty much any simple tractor.

N80,

Your points on pulling a 2 bottom or what ever in "just barely" mode with a gear tractor and not able to with an HST is fallacious. There are 3 HP's that are important with tractors, as you know. (I'm adding this for those that are less knowledgeable). There is the engine HP and that's self explanatory. There is the PTO HP that is available for the PTO. But, there is also the drawbar HP. That's the load that can be pulled. It's a function of tire design, weight and 3pt design geometry. An L4400 FST, GST and HST will all be too close to distinguish in drawbar hp with the same tires, balance and geometry of all are practically identical. If anything, the HST may be able to pull a bottom plow better than a FST as the forward speed can be more easily modulated, but that would be speculation. I know I can pull a 2x14 bottom plow with a L3410 hst thru sod bound soil that hasn't seen tillage in 20+ years. With 99% probability a L3410 FST would not be able to pull a 3x14. I doubt that an L4400 would pull a 3x14, but it may. But it would take at least a 15 hp jump to pull an extra bottom and to get that hp gain, it's more than the typical cost difference gear to hst.

Maybe I do more loader work than most. Dunno. But I feel more is done in less time with the smaller hst tractor, and it's on the order of hours per day and not fractional minutes when there is a job exceeding a day's length. Typically with BH work, I use the old ford to dig the dirt, but the Kubota to move it. That gets the dirt moved faster for me.

Jake98 - Kubota FST is a gear trans, the letters stand for Fully Syncronized Transmission. Can't speak for the others, some are and some aren't. As far as driving like Mario Andretti, well only Mario and maybe his son Micheal fit that bill!

Mossroad - look up a picture of a proofmeter for a ford 801. Specifically a 841 or a 851/861.
