please help identify this plow

[ampsucker]

howdy, all!

not being around farm implements much, i wonder if some of you very handy folks would mind telling me what i have here. my uneducated mind tells me it might be a single bottom plow, but i'm not even sure about that. i read about folks who have middle busters, subsoilers, etc, but that doesn't mean much to me. hoping someone can help.

i'm also curious about pulling the thing. right now, the only way i could attach it is to my draw bar hitch or to a draw bar mounted on the 3-point. the way i'm seeing it, neither option would allow me to raise and lower it at the end of each row for turn around.

my understanding is the digging depth is controlled by a combination of the angle of the plow tip (crank handle), the guage wheel disk, and somewhat by speed. then, there is that piece of angle sticking off the back which may have something to do with it or maybe just keeps the thing tracking in the furrow?

is this just a cobbled together piece or is it pretty much as designed from the factory and how do you get the thing to lift at the end of each row without an upper link to the top three point attachment?

thanks for any help on identification and operation! here are the pics....

Allis Chalmers. Someone more familiar with models can tell you which tractor specifically, I'd GUESS it's for a model B. That is a factory built plow. A standard 3-point hitch or fixed drawbar isn't going to work without a fair amount of "re-engineering".

The coulter (gauge wheel disk as you call it) has NOTHING to do with operating depth, nor does speed. The angle of the bottom has SOME bearing on depth, but not so much as the hitch itself. The tractors hitch will determine operating depth. The coulter is to slice through sod or surface crop residue so the plow has a clean path.

Thanks for the quick reply!

If it all has to do with the tractor hitch, does anybody have a pic of a proper type hitch design? I wouldn't even know where to begin.

Does it have to do with height relative to the tractor wheels?

The plow itself has a double bolt hitch which I guess helps keep it straight behind the tow vehicle. It has about a 3-4" bushing which might allow it to ride up and down that distance when mounted.

any thoughts?

I have an old 10" Brinly (manufacturer)plow that looks very much like the picture you've posted. I bought it in the early 70s to use on a Ford 14Hp. garden tractor (I believe the tractor was made by Jacobsen). I think the hitch was called a "sleeve hitch" but I'm not sure. I remember it had a tube for the hitch pin. The tube fit inside the "C" type attachment on the plow. The plow was offset from center by using one of the hole sets in the "C" for the pin. There was also a plate which hung over the tube on the tractor hitch and which was pushed against the mid section of the "C" to keep the plow from swaying side to side. At that time (1970s)Brinly marketed many attachments for lawn and garden tractors.

FWJ, how do you go about setting plow depth? I've figured out by trial and error a good bit of my plows proper set up but depth still just seems like a matter of fate. I just assumed in my case that it was the level of the hardpan that determined how deep I could go.

thanks at ton for posting up that link, barneyhunts! i think that is exactly what i have. i read through the pdf manual at that site, and it gives complete adjustment instructions. it looks like a little work to get it all adjusted right, but i think i'll give it a try. my neighbor and i both have some garden spots i can work on, plus i want to plant some trees next spring, so i can start soil prep this year.

i'm thinking i may be able to attach it to the lower draw bar and use the lower link arms and a chain to raise and lower it. otherwise, i can use the 3pt draw bar and see if that will work without the upper link.

n80, check out the link barneyhunts posted and click on the manual so see a complete set of instructions for adjusting a plow. it may help you adjust yours depending on the options you have.

A plow should be operated at a depth of + or - 1" of half of an individual bottom's width. (ie, 12" @ 5" to 7", 14" @ 6" to 8", ect)

Some brands offered "deep draft" plows. John Deere as an example, once the "NU" style bottom was offered, had a deep draft 16" bottom that would operate efficiently at depths of 10" to 12". You'll rarely, if EVER see those style bottoms on smaller mounted plows (3 or less bottoms).

A plow with shares in decent condition have what is called "suck". That's the plows tendency to pull itself deeper into the ground. Worn shares will reduce that suck to a point where the plow struggles to get to proper depth.

3-point hitch geometry has some effect on a plows tendency to get to a desired depth. Look at the length of a typical top link vs. the over-all length of the draft arms. They're different. Their implement ends travel in a slightly different arc. As the hitch works through it's range of motion, the plow (or whatever implement is mounted) does NOT travel in a constant plane. As the plow raises, the tail end tends to lift more than the front of the implement. (Harry Ferguson designed and intended his hitch to do just that. Reason? To improve transport clearance when implement is raised fully) . As the hitch is lowered into operating position, a plow tends to retain a slight nose-down attitude (ever so slightly) Once the draft arms become parallel with the ground, and begin to place the implement ends BELOW the end attached to the tractor, the tail end of the plow lowers more SLOWLY than the front end. That's why a plow needs to be leveled IN OPERATING POSITION, and NOT while it's raised. That raised position is almost totally irrelevent to its OPERATING position. A plow that's properly designed and fit to a specific tractor will result in the draft arms being extremely close to parallel with the ground as the plow is at it's designed operating depth.

Ideally, the tractors DRAFT CONTROL holds the plow at proper operating depth, countering the plows suck from taking it too deep. Some tractors don't have draft control. Then you're at the mercy of position control, or in some cases, a gauge wheel on the plow. That gauge wheel "unloads" the plows suck from the hitch, reducing the traction advantage of a mounted plow. That suck pulling against the draft control (or position control) gives the effect of added weight on the rear wheels, resulting in increased traction. The plow has a tendency to rotate around the hitch, placing compression on the top link, therefore downward force applied to the front end of the tractor. That is the genious behind "The Ferguson System". Instead of wasting the energy generated by the plow, it's applied to the tractive efforts of the tractor. (smaller tractor does the same work as a larger, heavier tractor)

A plow bottom in good condition works simular to an airplane wing as it slices through the air. The landslide and tailwheel (if equipped) provide a certain amount of "lift" as the share and moldboard contour provide the downward force. In a perfect world, those 2 forces should be ALMOST equal with the plow at the desired depth of operation. Set PERFECTLY, a plow should only apply a marginal amount of compression on the top link.

By the same principal, the side-to-side skew achieved with the rotational adjustment of the offset drawbar applies pressure to the landslide to counter the force of the moldboard to make the plow trail directly behind the tractor. Set properly, no stabilizer bars/sway chains/ect are needed. The plow should follow CENTERED (on the plows draft line) behind the tractor.

Have you ever stuck your hand outthe window of a fast moving car and felt the air try to make your hand move up or down as you turn your hand? When you hold your hand "just right", you feel no pressure. Much the same principal with a plow. Adjusted "just right", it tends to want to travel in the desired path, be that up and down, or, let or right.

Soil conditions will have an effect on how well a plow operates, but its SHOULDN'T be the determining factor in the operating depth.

MOST, if not ALL tractors built these days had little, IF ANY design consideration for pulling a plow. Hitch geometry may possibly be less than ideal for working with a plow. The plow itself may not be of ideal geometry for the brand of tractor. Plowing with most "modern" tractors is an exersize in compromise. With the plow oriented perfectly while at operating depth, you may or may NOT have the ideal orientation as it ENTERS the ground. (or vice/versa) You do the best you can with what you have.

That probably sums up my experience using a generic tractor with a generic plow. I'm pretty sure my plow is a 14" and I may get it down 6 inches sometimes, rarely 8. I can feel the 'suck' when I have it set up properly. But I also noticed something else you mentioned. The front tip of this plow, which I guess is the 'share' is a bit rounded off. I wouldn't call it blunt but it isn't a distinct angle point either. Other than the bolts being rusty, it looks like it would be easy enough to put a new share on it. They are made by Crescent which is still making plow parts. I don't know the exact part number or anything but someone said it looked like a Ford 'type' set up. Temco has Crescent shares and the flush plow bolts too.

thanks for the very informative posts so far! really appreciate it. ;-)

i did a test pull this morning in what should be decent soil - a garden about two years ago with little ground cover. i hitched it to the stationary draw bar at the bottom of the tractor axle just to see what would happen. it was definitely a no go. there was only one mounting hole on that hitch and the plow unit wobbled from side to side and couldn't get decent penetration even more than an inch into the ground.

this weekend, i'm picking up my 3 pt draw bar with mounting holes all along the length. that should give me extra stability plus allow me to experiment with off-setting the plow left and right of the tractor centerline to get the wheels of the tractor into the previously plowed furrow. i should also get some ability to raise the plow at the end of each run for turn around.

i realize my set up may never be ideal. i'm thinking i may have something workable once i get a decent hitch and experiment with all the different angles available for adjustment.

as for sharpening the tip, i'm guessing there is a lot of finesse involved in doing that correctly. angles for maximum strength vs. penetration, etc.

so does this type of plow have name and what is it's usual purpose? my neighbor has what he is calling a "hard pan" under his garden which i think is just the same clay soil on top that his tiller tines haven't been able to reach and not a truly different type of soil - just more compacted but the same as above. from what the previous posts have said, if this is a 10" plow, i'll be lucky to get it 5" into the soil and that isn't much deeper than a tiller tine could go anyway. i guess there seems to be some value to "turning over" the soil as opposed to just busting it up, but there again, my farmer instincts and education fail me.

i'm sure it's been posted before, but can someone give me the basic advantages of plowing vs. tilling, vs. discing vs. harrowing, etc. it it all about particle size, root depth, type of soil, etc?

thanks, sorry to be so ignorant.
