napabavarian, First, don't feel attacked, I was just trying to be helpful. In automotive applications not involving towing or off road the choice of a tranny is pretty much like a girl selecting a fragrance or lip gloss color. Some major trucklines went all auto and it wasn't because truckers can't shift. These decisions are made by bean counters.

I have had several sports cars and somehow a sports car with a regular automatic tranny just doesn't seem right, sort of antithetical. Now if there are specific tasks to be accomplished there are criteria by which an advantage may be seen to be possessed by one or the other, auto or stick. Forget the MACHO issue and just look at performance. If I am having to start up on hills with max loads or pull a heavy boat up a steep slippery ramp or creep delicately in an off road situation, I personally prefer the auto. (been there and done that in all these situations with auto sometimes and stick others) Not because I cant feather a clutch, double clutch, heel and toe etc but because auto just works better in some situations (other than brain dead drivers type situation.)

If I were row cropping I would have a straight geared tranny with the least number of points of failure between the engine and dirt and the least wear items and or slippage.

Although I was trying for humor, through excess, the points I tried to make are, I think, defensible and valid. The difference between a HST and gear shifting in the HP loss area is negligible. You stated it as a concern or decision making criteria. I wouldn't want you to make a decision on flawed info. You might have a laundry list of good reasons for not wanting HST but I suggest fuel economy and HP loss are not valid ones.

I have operated JD without HST and they are just fine for what they are. They do what is intended but in my opinion HST will be more productive and less tiring to the operator in close in manuverinig situations doing FEL work and similar. I have to brush hog around lots of obstacles and HST makes it easier. If i were just going round and round in a big pasture, HST would be no improvement at all. Think about it. Why are there HST trannys? They must be better at something or they would have no marketing niche. I looked at my major uses and decided I would be doing a lot more manuvering than just cruising along. If you don't anticipate lots of manuvering then the expense of buying and maintaining HST is NOT recommended.

There are lots of reasons to select HST or reject it depending on your intended usages but HP loss and fuel economy aren't them.

HST is NOT the equivalent of an automatic tranny in a tractor. It is a manual (footally??) continuously variable transmission. A good operator doesn't just use the HST pedal as an off/on switch. Done right the operator uses the "gear" ratio that fits the situation. Some situations are continuously changing and that is an area where the HST excells as the operator can continuously and easily select the precise gearing he desires. If you don't forsee yourself doing work that would be made easier by being able to easily select the precise gearing you want and the ability to easily vary it as well as instantly reverse direction without using your hands, then yoiu probably should save your $ and not get HST.

If you want HD brush hog take a look at products by Hause such as the Cimarron brand. Cammon is a good supplier of HD box blades. I have worked and admittedly abused the heck out of my box blade and it has been totally bullet proof. I have managed to partially mangle the hydrauic hoses that raise and lower the scarifiers but they still work and don't leak. This is not a fault of Cammon but mine for not doing something to keep the excess slack out of harms way.

If you don't expect to ever stress your box then save $$ and don't buy a Cammon. Don't buy an Abrahm's tank when a Hummer is all you need. If you do anticipate really working a box blade pretty hard you will be time and $ ahead to buy a better quality than KK.

Jim. I wish you had been a bit faster with your well formed comments. It would have saved me from stumbling around trying to say what you said so clearly.

When I stay off of regular manual tranny tractors long enough I feel sort of out of control when I get on one. Yeah, I know... there are clutches and brakes and throttles providing many ways of slowing or stopping but... Once spoiled by the fine controll and finess provided by the HST in support of manuvering it is hard to appreciate the standard.

I'm sure there are still folks out there who think the starter on a tractor and the battery and alternator are unneeded expensive luxuries and points of failure. They prefer a hand crank tractor with magneto. Ahh, steam... thats the ticket, burn scrap wood or coal and water is easy to come by... don't need no refined fuels from foreign places.

I don't have one planned use, more a jack of all trades tractor with no use expectation to spend more time doing any one job than others, the HP issue has a bit to do with the choice between a smaller and larger tractor, with an HST I was considering a 4330, but with a gear drive the 3830 looked to be plenty.

The tight areas are all in the front yard, arround 1.5 acres, and with 3 small orchard areas to lightly disc and a garden to till, 120' long, 20' wide.

3 areas in the 1-3 acre range to keep rough cut mowed, and plenty of up and down in the terrain, arround 1/2 of the property is forested.

napabavarian, You have described what I think my HST Kubota is, a jack of all trades tractor, well all trades except backhoe. Can't put a Kubota hoe on my cab tractor. All life is compromises...

I used my tractor a lot in 3 years of house building. If it were larger I wouldn't have been able to manuver in tight spaces and it would have been less valuable to me. Although I have put in a few consecutive days of 5-7 hrs of brush hogging I hadn't brush hogged much for a couple years prior. I had a good controlled burn two years ago and anticipated another this last season but then a record drought triggered a state wide burn ban. I eventually couldn't stand it any longer and just mowed it down. (Best laid plans...)

It is precisely because I do so many different tasks, many of which require manuvering that I really enjoy the HST. I have loaded dirt onto a 10 wheel dump, dug ditches, trenches. Just yesterday I was unloading 50 gal drums of pelletized corn gluten (about 390 lbs plus the drum) from my pickup to the hay barn. I had to manuver in close to the truck to get a vertical lift on the drum and not have it swinging wildly when lifted. The HST just excells at precise work, "threading a needle with your tractor" is the way a previous poster so aptly put it"

This was a first for me. Earlier in the morning I had welded rebar lifting eyes on the drums to accept chain hooks. The drums were filled level full but had no lids or cover but it went pretty good and I only spilled half a cup from one drum.

I also have a tiller and disk but do only smaller areas as you describe not several acres at a time. So far the only discing has been to make firebreaks for controlled burns but will get around to other uses.

I don't have a monetary interest in any overarching HST consortium so I don't care what you buy. You can make just about any tractor do just about anything just not always an efficient or easy situation. I have a good friend who has a considedrably larger tractor than mine because he got a great price for the HP it has. It is equipped with a pretty powerful FEL BUT being a row crop tractor the front suspension was never designed to carry an FEL so although he can pick up really heavy loads it can break his spindles. He has been there and done that.

I feel that for maximum utillity, especially when you want to be able to do anything that comes up it is best to buy what can do pretty much everything with ease (except pull heavy plows and disks all day every day with low maint. In my opinion that is HST. In over 5 years of abuse I have had not a single hickup from my engine or HST. IF I were into row crops and had to plow and disk my 160 acres instead of use it mostly for pasture and house building were not involved I would probably have looked more favorably at an all gear tranny.

The Kubota HST is the only one I am familiar with but they are probably similar. there is a variable stroke device (swash plate?) on a hydraulic pump driving a hydraulic motor that drives a 3 speed gear box. You get 0-100% of which ever gear (low med hi) you are in (forward or reverse) no clutching at all to change from forward to reverse in a small fraction of a second, just a flick of your ankle.

Another thing to consider is that you don't hear anyone complaining that their tractor is too powerful and gets the work done too fast and easy. (Plenty of the opposite) Of course you don't want to seriously overbuy and waste $ to buy excess capacity that you don't need or use but trying to get by on a tractor that just doesn't quite have the HP you really need is frustrating and a bad bargain. Something that hasn't got the guts to do a job without straining will be more maint prone and NOT A SOURCE OF JOY.

I have a friend with a brand new JD that the dealer promised was large enough to do what he does. He now calls it his toy tractor and hopes to be $$ ahead enough in a couple years to trade up. It works but it works slow and the implements sized properly for it are 5 ft not 6 which makes a significant diff when say brush hogging a 40 acre pasture. His JD brush hog can handle up to about an inch or so brush and then it doesn't seem prudent due to the light gauge deck and the ease of distorting it. And I thought my Kubota was a toy tractor till I saw some of the smaller JD. My Kubota seems HD INDUSTRIAL by comparison.

napabavarian:

I had a geared tractor for 20+ years. Now that I have a FEL (with PS) and HST, I will not go back. If you are going to use the FEL alot and/or do "fine tuning" maneuvering with attachments I would recommend that you go HST. Jay

I am considering pricing the GST, :)

The GST sounds like a great tranny. I wish I had one. Best of both worlds.

Napa,

Given the size of your lot, the 3830 in any configuration is plenty powerful enough. It is also quite a bit more nimble than the longer 4 cylinder tractors. I recently tilled up a 3 acre field with a 60" KK gear drive tiller. Actually, I tilled then cross tilled and was done in an afternoon. That's with an L3410 HST. Have also cut acres of fields with small trees using the BrushBull 600 medium duty cutter from Woods. The Woods design has a VERY heavy stump jumper that once going helps to power thru tough stuff.

Again, with your lot size, 5' attachments will work fine. But will take 20% longer than a 6'. The 20% time savings may cost you thousands of dollars in a larger tractor, higher fuel costs and more expensive attachments. Often, it's worth it. After all "time is money". Only you know for sure (when I was in your shoes, I didn't!).

If you are planning on doing some commercial work, the smaller 3830 will be nicer in residential settings and is easier to tow.

Just food for thought!

I vote on you buying a HST and a GST. Then shipping the one you don't like to me. Hey, a guy's gotta dream!

Put yourself in this position: You know that you don't know. You get lots of differing advice. You filter through it all and discover two competing technologies that are the front runners for your consideration. Ignoring all emotion and evaluating the facts you decide one of the technologies will most assuredly do everything you want and the other probably will too.

Now, do you risk the whole investment on the chance that the cheaper technology will do it all the way you would want it done or do you pay the difference and be dead certain of getting the performance you will want? I think the problem has come down to this.

napabavarian, Yeah baby, whatever you do don't get one of those HST thingies. They are way too easy to work with and therefore aren't as manly as other transmissions.

And that is even without considering all that fuel guzling HP wasting of the HST compared to straight gears. Take for example the BIG MISTAKE I made when I bought the Kubota L-4610 with HST. The geared model is rated to put out 40 HP at the PTO and my sisified HST only is rated for 39.5 which is a whopping 1.5% of loss. Most likely I have to burn about 1.5% more fuel to do the same job too.

It just isn't very manly to only use the clutch pedal when starting (darned safety lockout, probably ought to jumper it so I can start the engine with the PTO engaged and my foot on the HST pedal) and when engaging and disengaging the PTO.

At $3/gal that wasted 1/2 HP is the equivalent of paying 4 1/2 cents more per gal. Economic ruin is certain to rear its ugly head for me and the other poor unfortunates who think the HST is the best possible tranny choice for FEL and other highly manuver rich tractor activities.

If you are into row cropping and hardly ever expect to manuver much in close quarters such as FEL work and such then you will do well with a "standard" tranny.

Pat
Pat, PTO on an HST is geared, so losses are virtually the same at the PTO. The slight shortage on the HST is the addded losses incurred turning the BIG hydraulic pump even while youre not using it. HP comparison at the wheels would show a more significant loss on the HST. Thru gears you lose about 10%. That means your 40HP pto is run by a 44Hp engine. Thru hydraulics you lose about 20%, meaning that your 44 HP engine gets just 36 of those to the wheels.

Larry, Thanks for the thoughtful analysis. Whatever is hapening the final results are satisfactory and I remain extremely pleased with the L-4610 after nearly 6 years.

I guess I am paying a heavier MPG or gal per hour penalty than I knew but it isn't so bad as to change my mind when I consider how wonderful it is to operate. If I work the Kubota quite hard all day with few breaks I sometimes have to refuel before I quit but a more typical day burns less, way less, than 10 gal of off road diesel. I buy 300 gal at a time so I get a fair price.
