Cashboy Posted December 20, 2019 Share Posted December 20, 2019 I recently bought this second hand rice machine that is on a small Isuzu lorry. I paid 15,000 bt for the rice machine only (not lorry it sits on) and I saw it being used last in the 2018 harvest. I believe that it weighs about 800 Kgs This machine is only used about 6 weeks a year and the villages struggled to find available machines this year. So I decided to purchase this machine for the my village and local villages to use. My idea is to build a general trailer that can be towed behind my pick up truck or a tractor; and this rice harvester can be bolted on to the trailer for the 6 week harvesting period. Has anyone any idea what kind of horespower (PS or kW) this machine requires to run it smoothly and efficiently? I was even wondering if a Kubota Diesel engine as on those tillers would be adequate but they seem to be between 8 and 14 PS/2400 rpm Because I was looking at buying one of these diesel engines to drive a generator, Link to comment Share on other sites More sharing options...
ireckonso Posted December 20, 2019 Share Posted December 20, 2019 There are a lot of rice exp. people on here so you should get an answer, but looking at the pics im guessing quite a bit of power to turn it will be needed. Link to comment Share on other sites More sharing options...
kickstart Posted December 20, 2019 Share Posted December 20, 2019 We have one in our area ,that is mounted on a truck chassis ,the engine is 6 cylinders. If it is going to be used in the village mount it on to a trailer ,ask around for a Ford 660 , or something similar ,and use the tractor PTO drive to drive rice thrasher , A Ford 6600 is rated at 79hp ,may be a bit much ,but they are plenty of Fords about ,you might be able to do a deal with the owner hirer one when needed ,a 50 hp Kubota might do the job . Can not see a single cylinder engine having enough hp for the machine ,you could buy a Ford tractor they are about 300-400 000 baht ,that I would say is not a good option .

Dumbastheycome Posted December 20, 2019 Share Posted December 20, 2019 The thresher unit is usually mounted on a small truck because the driveshaft from the truck once in position is detached from the truck diff and attached to the thresher. A small single double power unit might have the horse power but not the same torque as say a 4 cylinder truck engine to maintain revs under load but maybe. I would suggest checking out the viability of a second hand engine from a dismantlers yard and compare that to the cost of a stationary diesal unit. Plus checking out the setup on the original or another similar to see what gear they use from the gearbox for optimum revs of the thresher. I have a lot of experience in helping toss rice into one but in thinking back the engine did not seem to be at any high revs so maybe direct drive in top gear was used?

farmerjo Posted December 21, 2019 Share Posted December 21, 2019 My friend has one mounted on a permanent trailer and uses a Kubota 47 horsepower to drive it. Not sure if same size machine or not. Is there a name plate on it? http://www.thaisengyont.com/en/2016-02-05-02-23-32 Link to comment Share on other sites More sharing options...
ireckonso Posted December 21, 2019 Share Posted December 21, 2019 Probably be a good idea to go thru all the bearings, pulleys and belts before next season too. Link to comment Share on other sites More sharing options...

thoongfoned Posted December 21, 2019 Share Posted December 21, 2019 cashboy if you are looking at buying one of the small kubota engines have a look in dohome, they have "copy ones" for half the price, goldenbow is the brand name. we have been using the goldenbow units for the past 8/9 years, i have 3 on rotation at the mo, run them 24 hours a day 365 days a year, for the past few years, easy to fix/maintain. generally we get a new one and it will run as stated above for 1.5 years before its needs fixing, can rebuild one for under 5,000baht parts/labor should service every 100 hours but i leave them till 200 hours +...

Not sure if same size machine or not. Is there a name plate on it? http://www.thaisengyont.com/en/2016-02-05-02-23-32 Is this the name plate? I bought the machine from the local government. I believe that these machines were available to the villagers to do their rice harvest. The machine was up for sale and lots of villagers wanted to buy it but nobody could afford the 15,000 bt for it. This year we struggled, like others in the villages, to find anyone with an available machine. So I thought I would buy it, refurbish it, build a simple trailer for it and drive it off a PTO. We used the machine 2 years ago and it seemed to run well on the drive shaft of that old Isuzu Lorry. I have now been told by the village leader that he thinks the rice harvester can be run off the PTO of a Kubota L3608. An L3608 = 36 HP tractor so probably give 33 HP at the PTO. It would appear my harvester is on a 2m long frame that would make me think that it is a 6ft model? It is very odd because when I looked at http://www.thaisengyont.com/en/2016-02-05-02-23-32 for power required: It states engine HP of 18 HP but tractor power of over 85 HP ! That does not make sense to me; anyone have an idea? I had been looking at buying a Kubota L5018 that is a 50 HP tractor for farming the 25 rai we have and for using for construction work. So would that be adequate? So anyone know where to buy off the shelf leaf springs and axles to build a trailer for the road? As I believe the machine is less than 1,000 Kgs don't require brakes on the trailer. Link to comment Share on other sites More sharing options...

I had a look and not sure if same manufacturer but am confident that the HP reuired will not be much different. I believe my machine is the 6ft model. However I do not understand the huge discrepency between an engine driving it ( 18 Hp) to a tractor driving it ( 85 HP ) I am also told a Kubota L3608 would be sufficient to power it by the leader of the village that operated it but that is only 36 HP. So have to hope a Kubota L4018 (40 HP ) or L5018 (50 HP) tractor will be powerful enough. When the machine was used on my farm on the old Isuzu lorry it seemed to be working effortlessly.

I thought 15,000 bt was a bargain but your family member paying 30,000 bt with a trailer and PTO coupling sounds like a robbery depending on how big the cylinder is on it.

Lacessit Posted December 21, 2019 Share Posted December 21, 2019 Is there any kind of workshop manual for such a machine? That's what I would be looking for. Link to comment Share on other sites More sharing options...

I'm not experienced with them but think it would come down to the gearing to maintain rotor speed under load. A tractor may have 540/1000 rpm pto at x amount of rev's My grey market Kubota has a 4 speed pto gearbox.Don't know on new Kubota's. Not sure what gearbox in the truck it's mounted on and what gear and rpm of engine. A quick look at my DC-70g harvester 5 and half feet long rotor and think the rotor turns at about 1500 odd rpm at 2700 rpm with 70 horsepower engine.Of course that also requires power for the hydrostatic drive.

Contact them they will tell what hp you would need . Link to comment Share on other sites More sharing options...
