Disc how much

[void777]

How big of a disc can I work with a ym2000 fairly soft ground until August :confused3:

 

[clemsonfor]

5 foot will be the max and then that depends on how heavy aND how many and what size disks. But assuming a very light say like Howse model you probably will have to control the depth or else it will han you up.

My LMC disk is about 4.5ft wide and has I think it's 12 disks 16" in diameter. And when there cutting and buried up to the axles it's all my tractor wants.

How much does your tractor weigh?
How much horsepower?
2-WD or 4-WD?
Rear tires filled with air or liquid?

it will help to load your tires too

He has a YM2000 if I am not mistaken. So it's 24 engine HP. Weighs about 1800 pounds unbalsted and is 2wd.

My tires are loaded as well with mine.

MAYBE could pull Disc Harrow with 16" diameter pans for Secondary Tillage; i.e.: leveling plow furrows or working a kitchen garden annually. Implement only as wide as outside-to-outside tire width.
OP says soft ground, so draft force will be high.

Tractor does not have enough weight nor horsepower to pull a Disc Harrow for Primary Tillage; i.e.: breaking ground.
Primary Tillage requires pans of 22" diameter or greater.

Better to shop for a PTO powered roto-tiller.

Roto-Tillers and Disc Harrows are both soil mixing and smoothing equipments.

2 wd tires are foam filled was filled before i bought it wt 1500lb + fill

 

[void777]

guessing on the wt

 

[void777]

Guess its time to look for a rotor tiller it might be best idea thanks for the help people.

 

[winston1]

Might find a 3 point tiller for not much more than a hand operated if you have patience.

Trator Data lists the Ym240 which is basically the same tractor with a few things that really don't affect the weight....at 1696 pounds. I didn't pull service manual out but its for the 240 so it should say the same and that number sounds right.

So basically even if you your selft only weigh 100 pounds your at the 1800 pound mark there, but we will say 1700, which is what the tractor by it self weighs. I bet that's dry weight so add 40 pounds for fuel and another 60 pounds for hydro fluid and oil and water, but I think at that point were splitting hairs...haha.

for what its worth I can break the virgin ground (well unturned in decades) in my fields if I do like 6 passes. I pile like 250 pounds up on top of my disk harrow. Look at my signature. I list the LMC disk. It is a 12-16 ( I was on my phone before and I don't see the signatures). Which means 12 disks 16" in diameter. There slightly wider than my tires which are in the wide stance which makes them close to 4ft wide. I am not imagining using this disk I actually do. This is in from red clay to sandy-clay loam soils. Like I said its not a fast thing but it does it.

Each to his own.

When I moved to Nevada, I bought my first tractor, a YM 3000. As a incentive at the dealer, I was offered a 5' disc at dealer cost and I bought it. It pulled with little resistance behind that tractor, little penetration as well. In the end I stacked 500+ pounds of cement blocks on and still only managed to go 3" or so deep. I learned the ground can be hard out here. I was only using this disc for weed control for fire breaks, so it didn't matter much. Along the way I acquired a 5' Howard rototiller very cheap. Rototilled at full depth wasn't much of a load for this tractor on the pto. This rototiller does my garden now and goes the full 8" deep in one slow pass. If I had to do it again, wouldn't buy the disc for a garden, at least with my ground, could have made 20 passes and still not had the soil preparation I wanted, or the weed control. YM2000 has much less weight and hp than the YM3000 I was using. I realize that in softer soil, results could have been different. A 5' disc behind a YM2000 ( 2wd ) in soft soil might end up being might be more than the tractor can pull at a decent cutting depth. The disclaimer here is different areas = different results.

Exactly different soils equal different results.

And I'm not saying at certain points I wasent holding the fifferences lock either.

 

[clemsonfor]

"Holding the diff lock either".

FWIW a 5 ft disk came with my YM240. The seller said one reason he was selling this combo was this wouldn't work to disk his irrigated walnut orchard. (Soft but I suspect slippery). I've tried it here on ground that has been disked annually for years. It usually takes a couple of passes just to get through the grass and thatch even with ballast, then tills a couple of inches deep. More ballast stalls the YM240.

Then I bought a small disk, I think 40 inch. (I have photo of both on here somewhere). With 200+ lbs ballast it will go in a few inches.

My conclusion is these are for levelling the surface after real plowing, and useless for primary tillage. They may be adequate for fire breaks and similar surface weed control.

Disc Harrows are not effective as single pass tools until Disc Harrow weight bearing on each pan reaches 50 pounds per pan, this starts with 20" diameter pans. [ Take total Disc Harrow weight and divide by number of discs. ] Nine inch pan spacing penetrates better than 7" pan spacing because of reduced float.

A Disc Harrow with 16" diameter pans has about 37 pounds bearing on each pan in 10/16" Land Pride DH10 configuration. This is a unique configuration, from what I can see in Land Pride's pictures, with five 16" pans on the front gang, six 16" pans on the rear gang. Pan spacing is 7-1/2". A Disc Harrow with same 412 pound overall weight but "normal" 12 X 16" pans would have 34 pounds bearing on each pan.

In my opinion, adding 200 or 250 pounds of weight to a 400 pound Disc Harrow will break a frame weld sooner or later. After one weld breaks, which could take several seasons of stress, other frame welds usually let go in succession. Two frame welds may let go in unison. With 7-1/2" pan spacing it is safe to say Land Pride engineers designed the DH10 DH for Secondary Tillage.

A PTO powered roto-tiller is the better implement to mix and smooth soil with a 1,700 pound tractor.

Thank you every one for your input think I'll go for a tiller 48in-54in.
