Hydrostatic transmission for hilly land?

[Rob Bone]

We have 17 acres of sloping to hilly land, and currently have Fiat 45-66... 4WD tractor (45hp) Have been considering upgrading, and wonder if hydrostatic transmission is any good on hilly land, and also what repair & maintenance problems arise.
Hoping I can get info on the pros. & cons. of hydrostatic trans.
Thank you
Rob

I have a 4520 e-hydro. I dont have a lot of hills. I can say when pulling heavy loads - I have to go down to low range.

I would ask the dealer for a demo. See how it does.

I agree, ask for a demo if a HST trans, and a powershuttle. Will be the best way to find out first hand.

Thanks Darin. So many tractors seem to have the hydrostatic trans. so at this point it's a general enquiry if that trans. is any good on hills. When I say upgrade, I mean to a later model with lower hours, but not a new tractor, and most likely will be from a private buyer, so demo probably not possible.
Thanks,
Rob

:welcome: I do not have many hills around and the ones I do have are not a problem for my 5010 HST tractor. So far have had no repair problems with the HST. I have changed the HST filters and fluid once and I am at 355 hours on the clock. The next HST filter and fluid change is at I think 500 hours but I would have to check to be sure. I have had 2 other tractors both gear models and for me the HST is by far the easiest to operate for what I use the tractor for and wish I had purchased one sooner.:thumbsup: :2cents: Good luck.

I have a L4400, 46 Horsepower, Kubota HST. I also use it on a lot of hilly terrain including slopes up to about 32 degrees. The great about the hydrostatic trans is I rarely use the brakes even on the steepest hills. I have used standard shift trans for years but I see the HST as a safety upgrade as I can change directions on the hills and never pass through neutral or risk missing the gear while shifting. As far as maintenance I have only had to service the HST with fresh filters and fluid at 400 hours.

Our primary hill tractors not including three SCUTs are a Kubota L5740 HSTC and M8540 HDC, both work quite well, never had any mechanical issues with either or prior L5030 HSTC.

I have had three JD with HST: 2210, 4720 and 4520. Never any transmission issues.

I have a Kubota L4610 with HST. I have pretty hilly terrain, not crazy steep but hardly any of it is flat. With loaded tires and box blade on the back, I have to stay in medium almost the whole time. I can use high when going up the street but really have to rev the heck out of it.

You will most likely hear quite a bit of "whining" from the transmission on the hills. As far as maintenance, I just changed my hydraulic fluid and filters, cost me $350 but I won't have to change the fluid for another 400 hours.

There is very little maintenance and for loader work an HST is tough to beat.

Make sure it is a three range hydro! With two range you will be in low all the time and that is with about a 4mph max speed where a three range would give you about double that in the middle range and still have good power.

What he said. I live in Branson, We don't have any flat ground. I would not have anything else. Much safer and easier to use.

I agree with James. Both I and my neighbor next door have HST tractors. Can't imagine mucking around with gears any more. We go down to the creek, dropping 100 feet, virtually every time we use the tractors.

My tractor has HST - I pull heavy loads, up to 15K lb on my farm wagon and have never had a moments problems. HST is very handy with FEL use also. I do have one substantial hill in my driveway and it has never given the tractor any problems. Kubota calls my transmission - hydraulic shuttle.

It seems to be universally agreed that HST works great on hills and I agree. I very seldom use the brakes on hills or any other time as the HST works wonders for braking and if you have and use 4WD you have 4WD slip braking or three wheel braking if you use the differential lock. The only big disadvantage to HST versus geared transmissions is it takes more power and fuel to operate for a given task and it is not nearly as efficient for ground engagement attachments. I have found that those are really minor trade offs for the increased ease of use of the multi tasking tractor.

They work well. All I had ever owned were gear shift tractors until last year. Lots of hills, some quite steep and I generally kept off of them as holding the brakes and shifting was a tricky proposition, esp. with a balky transmission. Not an issue with HST. One thing to watch, however, is on the Deere 3x20 series it's very easy to bump the range shift lever if you're frequently turning your body to see behind you and wind up in neutral. Not too bad if you're backing up a hill but can get pretty exciting if you're backing down, get rolling, then need to turn around to get the brake foot extended and stop fairly quick in reverse with a light front end.

No question HST is better for hilly country (I have mine up in the mountains in Colorado). Also for loader work, or pretty much anything except field work where one is pulling at constant speed all the time. HST is 10-15% less efficient than a fixed gear so not the best choice for field work, although it can do that too. The main advantages of HST in the hills are you are always in gear, can creep at any speed in touchy situations, can reverse without changing gears, and if you just take your foot off the tractor stops (although I usually need to set the brake to keep from creeping, if there is much of a slope). HST shares the tractor hydraulics so there is little additional maintenance. As someone else said, look for at least a L-M-H gear range, and lo/hi in each gear is even better.
