Looking for info on a heavy direct drill I saw in the Profi Worlds Most powerfull Tractors video. I think it was called "Yielder" and was ca. 6 meters wide and very heavy. I guess it was used in Washintong stete area.
Anybody have a clue of what I am talking about?
Still not a lot of time to tractorsurf inbetween ploughingsessions. Drilled the first hybrid rapeseed today.

Yes, Laapa, the Yielder drills were huge end wheel drills with big hiillside combine tires on the end, about as tall as a tractor. They had tremendous weight to force plow coulter guage double discs into the ground for grain insertion. I think they also had a coulter disc ahead of the seeding discs and maybe an extra set of discs for fertilizer. I never saw one up close. Most had to be pulled by a Versatile or Steiger type tractor. I think they were made for no till operations in the Palouse and with fall seeding of wheat, the ground can be baked extremely hard due to clay content of soils. That may explain the massiveness of the drills. I don't think they were cheap price wise either compared to regular drills used at the time before air seeders were known in this area. They were built in Spokane, Washington later on. I don't think they have been built for years and were quite a rare bird even when in production. An outfit in Palouse WA builds something a little like that though they look smaller, and they look more like press drills with wheels behind instead of packers. I think they build them pretty much on a custom basis. I have never seen one in use here though a guy up the road has a Yielder I think that he uses though I don't know much about it. He has tried all kinds of different drills including a Horsch. Most used drill is still standard double disc with 6" spacing since we have to have traditional seedbeds for most legumes.
There were several articles in various farm magazines about those drills. I think there was one called Pioneer also. Were very expensive as Red_Painter stated. There was one in the area several years back. Not sure if it was a Yielder but was of similiar design.The owner used it for seeding winter grazing on rangeland. He used a Challenger 65 to pull it.
i am leaning towards these machine we use over here if i had a choice, have used old JD750 drills, 15ft wide each, two on a toolbar, i got soybeans into some pretty deep stuff, and if you don't put the pressure on the hydraulic cylinders you can get the coulters to sit on top, good for small seed
sure disc coulters have bearings and stuff.......press wheels yadayada.....but they truely are nice machines .....we have also the JD1560 on the farms.....later model of the 750 drills, and have a air seeder its a JD1850 with a commodity cart in front, this does a good job, it is getting worn, discs are wearing, seed shouts are wearing (problem with smaller seeds, you just blow em away, but we have had some good results in some pretty hard soils.....our southern farms planted soybeans with the 1560 this year, only letting the drill get half empty before filling!>......keeps the weight on the coulters....
be sure you do your home work, i haven't seen to many yeilder round, lots of great plains and JD and kinze (15inch rows) sold here .......
thats my thoughts.........

In Profi-magazines Worlds Biggest Tractors video I think there are 3 Yielder-drills appearing. One being pulled by a Steiger, one by a Cat and one in a shed. All from the Washington area. Led me to belive they might be quite common there.
I'm quite familiar with the Yielder drill here in North Dakota. We've got 4 of them, and have done a fair bit of custom seeding with them. There were different models made. Ours are the HD series, which are even heavier than the aforementioned end wheel drills. We have 2 25 footers, a 20 foot unit that we extended out to 23.3 feet, and a 25 foot unit that we extended out to 28.3 feet. We've got them set up with 5 inch triple rows with the fertilizer banded every 20 inches underneath the center of the triple rows. When the drill is full of fertilizer and seed, the tractor carries approximately 45,000lbs. on the hitch, so we've got beefed up hitches on the tractors. The 25 foot drills have 4 30.5-32 tires on the back. If you'd like any more information, let me know.
