disc plow

[rich1]

Can i pull a two disc plow with a 20 hp tractor thank you

Are you talking about a plow or a disc? If your atually talking about a 2 bottom plow ( one that cuts 2 trenchs at the same time)
then 20 hp is usually not enough. Its likly you will exceed you traction before stalling out the motor but either way your over the capacity of the tractor.

Monroe Tufline is one of the few manufacturers still producing disc plows.

Twenty horsepower is not enough to pull a two disc plow.

Agriculture TDP Disc Plows - Monroe Tufline


If you have four wheel drive and some type of ribbed tires, you can pull a 10", possibly 12", old school single bottom moldboard/turning plow.


How deep do you want to plow? What is your soil?

Brinly is still the key supplier of light weight equipment:

"Two disc plow" conjures up something like in my mind's eye. I've read that 30+ HP are recommended for that size.

A true "disc plow" requires considerably less HP than a moldboard plow. Depending on soil conditions, 20 HP might 'just ' do it. In peat soils we would operate at speeds of 4-5+ MPH. Difficult to keep straight furrows if you have varying soil conditions in your field.

I used to pull a 2 disc plow with a John Deere M. Tractordata.com says it claimed 18 hp at the drawbar. The disc were worn and not very big. It pulled it fine.

The point of discussion shouldn't be HP. It should be the tractor's physical size/weight.

Your "Tractor" info isn't complete enough to know about that.

Are you talking about a plow or a disc? .

he said disc plow. it's a like a bottom plow only using large discs.


To the op. Unless it's a darn small disc plow.. I'd suspect you will not like a 20hp machine on a 2-disc bottom plow. if it is sand or pre-turned or tilled earth.. -maybee-

i wouldn't spend money on an implement that i could only pull on tuesdays with gum on my show with a favorable wind though..

I pulled two big disc hillers with my 18.5 hp 4wd JD 4010, with the discs discharging to the middle. I'd think if I turned one of the discs so that they discharged in parallel, like you're asking, that it would do it. Not sure how well it would hold the line though. If you had a good trail guide wheel to help it hold the line, that it would work.

hillers are a bit of a different animal.

enough weight will be needed to make use of traction too.

a 40 hp tractor that is light and can't get traction may plow worse than a perfectly ballasted 30hp machine.

Yep. That was my point. I've plowed many, many acres with an 8N and 2 bottom moldboard plow. Can't remember their HP, 24 maybe??

8n, 27 pto depending on who you quote. 23 for the 2n/9n if using 2n/9n head..

I agree. I assume the OP is talking about a disc plow as pictures in one of the earlier posts show that have 30+inch diameter discs. Totally diff than hilling disc attachments. They require considerably less HP/weight than a moldboard plow.

We used to pull 2 16" turn plows with our old Jubilee all day long 20.2 HP but tractor data says 26.8 at the drawbar which I find hard to believe.

Dad pulled a set of Ferguson 3pth 2 bottom disk plows, 26'' disks, with a nearly new gas 3000 ford, 14.9 x 28 ballasted rears. He pulled it in 2 or 3 gear and the Ford "didn't want no more". Plowing 8-10 inches in mostly Baxter clay soils. The plows were very heavy and made the tractor light in the front. In my experience disk plows leave a field very rough and hard to disk.

a jube with the 134 red tiger has about 33 hp belt anyway.. 2 16's is quite a load..... pre worked earth or sand?

Used a borrowed 2 disk plow to do my field with my L2850. Needed 4 wheel drive. No problems. However, I agree with the rough field. Had to put the seat belt on to run the disk.

You're moving the same amount of dirt in a disc hiller with discs opposed as you are with the discs parallel to each other. So, a given hp/drive (2wd heavier tractor or 4wd lighter tractor) will pull it.

Problem with a lighter tractor is that the side force generated by the parallel discs could throw the tractor into not going straight. That's why I said that a disc plow with a good trail wheel may work on a light tractor.

This is what my little Gravely tractor had with a single rotating plow, a trail wheel of sorts that kept the tractor going straight.

It wasn't a "trail wheel" on the Gravely, but a leading set of wheels. With at least one wheel up against the ridge made by the previous plow run, the machine would go straight.

Both, pre-worked for years and also fresh cut in fields not touched in years. Some of the soil was sandyish!

pre-worked and sandy are a bit easier to turn. lets you get away with less engine to plow ratio...
