riceyummm Posted May 17, 2016 Posted May 17, 2016 Second hand, I'm not sure what it's called in English, ผ่านยกร่อง in Thai (pahn yoke lawng). Appropriate size for a JD 5610, 75 hp tractor. Anyone know of one for sale in the Khon Kaen area?
colinneil Posted May 17, 2016 Posted May 17, 2016 If you are near Khonkaen, go south on mittrapap road. Approx 10 kilometers, their is a company making them. It is on the north bound carraigeway.
drtreelove Posted May 17, 2016 Posted May 17, 2016 In English its called a 'disc harrow', often shortcut to just 'disc', and the operation is usually called 'disking'. With the dual gangs of opposite facing discs, it cuts, mixes and throws the soil in opposite directions and leaves a relatively smooth soil surface, as compared to plowing where the soil is completely turned over. It is good for general cultivation and pre-planting field preparation, slicing and mixing crop residues and green manure crops to incorporate organic matter into the topsoil. It cuts to a shallower depth than a disc plow or mouldboard plow and is less destructive to soil structure, although still not acceptable to 'no-till' farming systems, especially orchards, where you would be disturbing the surface absorbing roots of the trees. With a 75hp tractor you could pull a much larger disc harrow than the one pictured, and get a better result, unless you're trying to cut too deep. I've pulled a larger one with a 40hp diesel conventional 2 wheel drive agricultural tractor, Set the depth to different levels for subsequent discing, to avoid forming a hard pan.
drtreelove Posted May 17, 2016 Posted May 17, 2016 And its a less time and fuel consuming operation than a rototiller. And less disruptive to soil structure than rototilling. Although different, depending on appropriate use for what you need to do. https://www.youtube.com/watch?v=Wxb8O_rwldQ

Thank you for your very informative post. Would you call these 'offset discs'? As you point out a set of discs this size won't require many hp.

colinneil Posted May 18, 2016 Posted May 18, 2016 Sorry i cannot remember company name. If you travel along mittrap road, you will see them. They have a large display area clearly visible from the road.

Hello Doc, Thanks, good info, knowing the English name makes it a lot easier to search the net. As far as getting a bigger one it's a matter of cost. It may be more fuel efficient in the long run but the initial outlay is more than I want to spend right now.
Gary A Posted May 18, 2016 Posted May 18, 2016 Sorry but it's not a disc harrow. It is commonly known as a ridger. It is used mostly for planting sugar cane. You lay the cane in the lower part of the trench and rake the dirt over the cane.
kickstart Posted May 25, 2016 Posted May 25, 2016 I think what the op was referring to was these type of Disc Harrows ,found them to day ,the tractor is a JD about 75 HP 4 wheel drive . The discs themselves are a scalloped disc better for cutting into a lot of maize stubble or sugar cane leaves , better than the normal type of discs . The guy driving the tractor said he got them second hand from Khon Kean ,30 000 Baht , they where made in Pattom taine, north of BBK ,by a company called SP, you can just see the phone number Google them they should come up

As Gary A said in post #9 it's a ridger. We ordered a larger one, appropriate for our tractor, from Kalasin.

slapout Posted May 28, 2016 Posted May 28, 2016 I have never seen what the op says he is hunting for. The you tube video that treelove presented is what I call a tandeam disk. The picture kickstart included looks like only one side of a tandeam disk I have ever used. Never seen or used anything like it. You want/need weight to put the disks into the ground and keep it at the depth desired. Thus the frame that is used in construction of a top of the line disk will be quite heavy, some are solid iron depending on width of the unit.Some people want/ prefer scalloped cutters others use round with no scallop, depends on price and individual preference. When set/ built right these disks can replace mole board plows, cover way more land in a fraction of the time and leave a smooth culvaited surface ready to plant. Very popular in low tillage farming.

I can see what you mean ,I have used what you call a tandem disc .like the set in video and they do make a good job . but that set would be too light for most farms . But what you write about would work well here in Thailand , but where we come from these would be semi mounted ,that is the discs in a frame ,being pulled from the draw bar, not being 3 point linkage mounted ,but here in Thailand your average Ford would not be able pull big set of discs, also most older Fords do not have the spool valves to work the hydraulics , to lift the frame at the end of rows etc. the newer TS models, second hand imports, will have spool valves ,Kubota tractors ,do not have any spool valves at all , would take a lot of work to fit some . If you could get semi mounted discs here in LOS , then a set of semi mounted one pass cultivators ,would make a job good of land work( Google them), something a Thai engineering firm could make , no 3 disc and 7 disc ploughs ,one pass ,and then drill ,would save a lot of time and money .
