Yanmar - hydrostatic transmission?

[JungleBiker]

Does anyone know if the Yanmar tractors sold in Thailand have a hydrostatic transmission?  I'm interested to buy a compost turner. A small one that only requires 23 hp at the PTO. The supplier said:

"Your tractor must be capable of 14 feet per minute (or less) forward creep speed at 540 PTO engine RPM. Speeds this slow are only possible with creeper gear or a hydrostatic (infinitely variable speed) transmissions. A conventional (standard) tractor transmission will not go slow enough to correctly operate any tow behind compost turner."

 

Thanks,

JB.

I assume you are going to windrow your compost and wonder what the cross sectional size of the pile will this 23Hp turner handle? I also assume that you do not need to use the turner to mulch up the inputs to the pile (bales of straw). The only machines I have used were much bigger (200+Hp) case tractor pulling them.

Still with my old tractor what you are proposing sounds doable for me. Will follow with interest.

These seem to be traveling at more than 14 ft/min. 

 

Slowest small tractor i could find in Thailand by surfing is 1.6 km/h or 266 m/min.

 

A self propelled small one is around $7500

No tractor to buy.

My little Hino is rated at  about 18 hp at the PTO ,a second hand imported one  it has a 3 speed  gearbox, and a 3 speed spliter box, in bottom gear it bearly  moves, I would say no more 14 feet/minute ,a bigger  modal  of say 25 hp engine would give you  about 18hp at the PTO ,I would  say the gearing  would be the same .

I read what your supplier said,  but I still can't see why you  can not use the tractor clutch to control the speed.

I have a rototiller (rotary hoe) for my tractor (28Hp 4WD) which functions perfectly in low range 1st or 2nd gear. I haven't measured the speed but think it would be faster than 14ft/min. The workings of the two implements are basically the same and I fail to see why the turner needs to advance so slowly. Please explain this to me.

I have thought of using the rotary on compost but as it trails the tractor instead of being at the side, the tractor would basically demolish the windrows. I have used the FEL to "turn" compost but will stick with my two 3 box compost systems as I doubt I will need more than its 9 cubic metre capacity.

As the guys have said,as long as the tractor has a 2 speed gearbox(hi/lo)and 540(Not 1000) rpm it should be fine.

What you want is to make sure they have built in a slip clutch or minimum a shear pin to the PTO shaft to protect the tractor and machine on the 1st couple of passes.

Thanks guys for your replies. 

 

The machine I am considering is this one: http://www.frontierindustrial.net/mighty-mike-windrow-turner.php  

 

Windrow width and height 80 inches x 40 inches. That's roughly 2m x 1m. 

 

In my first post, I pasted the statement made by the supplier and the bolding was by him not me. Either a creeper gear or hydrostatic transmission. I assume the slow speed relates to the size of the windrow. A small machine/tractor (slowly) turning a lot of material?

Thanks. I saw hydrostatic steering mentioned but not hydrostatic transmission.

Hi JB,

Most of the older japanese tractors have a creeper gear.

This is a picture of my Kubota L2201 gearbox arrangement,it's the red lever at the back side witch changes the gears to creeper speeds.

My Morooka MK-80 has hydrostatic transmission and PTO

You have all the best toys!

 

Jungle,

 

Saw a Multione loader yesterday so they are in Thailand. They have hydro-static transmission but sadly no PTO. So you would need a self powered turner.

Thanks Farmerjo. Is there any particular place in Thailand that you would recommend to find such kinds of tractors? What sort of price range?

    Where to buy a tractor? I am in Lopburi province, and my Hino  I bought locally, we have 3 tractor dealers near us ,all selling second tractors.

You are in Laos,?would have thought they should be somewhere near  Nong Kie, could ask in  TV's Issan foram, if we have some dealers near us , they must be some near Nong Kie , or find a farmer and ask where he brought his tractor.

Often driving around I see a tractor parked up with a cardboard box  on top saying for sale.

As for prices  for a tractor of 23HP at the PTO , you will an engine rated at 28-30 hp , would be about,100 -120 000 baht ,

depending on the make Hino's  and Iseki tractors  tend to hold there prices, the Kubora range of "Sunshine" tractors have hydrostatic   transmission, most are 4 wd ,for some reason tend to be more expensive.

Most imported tractors are getting on a bit my Hino E184,a4 wheel drive modal, was made between 1976-1979 , which now in the UK would almost make eligible as a vintage tractor ,one dealer near me has a lot of newer imported small tractors ,but prices would be a lot higher.

My tractor  only had 1400hr's on the clock ,we bought it , have had it for 10 years ,only problem clutch  thrust  bearing, sized ,but a local guy fixed that, only charged me  1000 baht  , had to replace bearings and seals  in the front wheel 4 wheel drive, one side  twice, and the engine does not use any oil , and FJ   did the cylinder head on his Kubolter ,so. these older tractors are not without they problems.
