3-Point Hitch 2 bottom plow

[Tx Jim]

Guess it depends on the bottom, my plows the moldboard is the width of furrow and point is only part the width of the furrow.

The double comment stems from the old rule of thumb to plow only as deep as half the width of the bottom, while one 16" not quite double one 12", here is the theory:

12" = 6" deep 6x12= 72 square inches per bottom

16" = 8" deep 8x16 = 128 square inches per bottom.

It will shock me if in real life situations many moldboard plowing depths are controlled/governed by point width. Your plow must have narrow cut & not full cut points. On moldboard plows I've used full cut points cut total width of furrow floor. Also 128'' isn't twice as much as 72'' either

I've always assumed that the plow shares are made to cut completely across the furrow floor but it sounds like that isn't necessarily the case?

A bit off topic but related to ploughs.

I've owned & plowed with a JD F145 4X16 plow & a MF(don't remember the model # 6X14. Each furrow bottom was as wide as plow share. Plow share size is determined by measuring from rear outside of landside to RH end of point when one is located behind the plow bottom.

Twice as wide,half as wide,14 inch or 16 inch,i think it fitting that responses to subjective questions include more than respondents know about the subject.

I'm trying to understand what you are saying here. Can you elaborate?

No, not in unbroken soil
In broken soil yah, but you need more Ooomph than that in virgin land.
I dropped a 16" two bottom in my unbroken soil last fall. It was a lot of effort for my 47 HP DK4710 to pull it. There were times it stopped my forward motion entirely, necessitating that I lift it.

As others have said, it depends on the soil type and condition as much as anything. Also, correct setup of plow and tractor is vital. I've been plowing with the outfit below for more than 50 years. It's a 1952 Case SC with a model BER 2-14 plow. 2WD, tires not loaded but steel weights on the wheels. Reports of the HP vary with the reporter, but I haven't seen any that claim more than 28.

I've plowed many acres of stubble and sod, which is what I think you mean by "virgin" land. About 30 acres of corn, oat, and sunflower stubble this year so far. I plow at 6-8 inches deep. Deeper or shallower and it doesn't turn over correctly, especially on sod ground. (that is why that depth is reccommended for a 14" bottom) Very dry and very wet soils are both harder to plow than moist. Row crop stubble is usually harder to plow than small grain. Weedy ground is more difficult than weed-free.

Your rig is a refreshing breath of air!

I pulled a 3-16 with about 25 HP over many acres of Kansas wheat stubble back in the day. It was not a hydrostat, no GPS, no power steering, no cab and the plow would plug in heavy straw. The soil ranged from sandy loam to nasty gumbo sidehills.

Edit: Also it was not FWA as the tractor had no front wheels, just idlers.

I did same task in Texas in my youth. But back then tractor HP was measuring in Draft horse not riding horse HP of today's smaller utility tractors

You are right you can plow what ever depth you want, sod is more sensitive to depth to turn over right though. I've gone 7" on my 12" but it doesn't turn the sod right. I run 5.5-6" and it turns nicely.

Yes 144-128=16 less than being double, so not quite double, another words it's about 80% more.

I have older 12" bottoms that use this share. They are around 7.5" wide.

Your photo with tape measure isn't the way I was taught to measure a moldboard point(share). As I previously stated standing behind standard/bottom to correctly measure MB point one measures behind standard from landslide or frog to RH end of point(share) similar to green line in photo below.

Your green line (and purplish one) on the first photo are 12" on my plow. It's a 3x12"

The long straight edge on my share/point runs parallel to the beam. It's not a flat piece of metal. Still isn't the width of the furrow on my plow. Brand new share, factory built IH plow.

Your plow has shares that I have never seen in person down here in Texas. Was your plow built in UK?

It's a Canadian built plow, ACE-8 bottom. They were very common in eastern Canada. The bottom is likely UK inspired because of British Commonwealth links.

Most plows that era were similar here, we tended to get UK things from MF, IH, Ford etc. Here is an MF I noticed come up for sale today:

Oops. I was originally sent here by an email from TractorByNet, and didn't notice that it's a John Deere forum. And here I am posting pictures of a Case. It's a wonder they don't throw me out.
To redeem myself, I'll post a photo of our 4600 with our 3-14 Ford 101 plow.

This website isn't a John Deere forum, it started out as a Kubota forum if I remember correctly. This is just a sub-forum for John Deere equipment.

I've never had a Case tractor but I do have a 3-14 Case plow I pull with my 5075E. There is nothing on it to say exactly what model it is, the best I can tell is it's an MRB. It has a regular category 1 3-point unlike your Eagle Hitch BER, the EX bottoms, and shear bolt standards. We had a 4-16 semi-mount Case with trip standards growing up, I believe it was an STA. It had a regular 3 point hitch too as we pulled it behind a 77 HP Deere. The thing I remember with the 4-16 was that you had to mount a tie rod cylinder with the rod pointing forward else you would pinch the bottom of the cylinder with the bottom of the front bracket for the cylinder and ruin the cylinder when you extended the cylinder to lift the plow. I will tell you a fully mounted plow is certainly handier to move around than a semi-mount but a little more work to level and set depth on.
