JD 10' - 12' disc, can I pull it? help me Indydir

I am hoping Indydirtfarmer or some of you other experts can lend a rookie some help. I bought a JD wheel disk at an auction last weekend. Its in great shape. No one was really bidding so I got lucky for once. It measures 10'6" across the front gangs and 12'6" across the rears. Discs are 20" smooth. Blades are 9" spacing, 8 per gang. 3" square tube frame. Of course the ID plate is unreadable.
Here are the questions.
Is this a 10 or 12 footer?

The bigger question, can I pull this with my NH 3930 4WD, 45pto hp? I've got the weight 5600lbs, but am I light on the HP? Some of the posts in here make me believe a little smaller disc would be better. I am not making a living with it, just tearing up my acreage occasionally. But I don't want to lug/overheat my tractor all the time either. The previous owner was pulling it with a JD 4020 which is 3 times the tractor I have.
Appreciate the advice.
Rick

Well, thanks for all the advice. First I'm going to try the disk and adjust the depth with the cylinder and back the angle of the gangs down some. If my 3930 won't pull it very well, I do have an old 8 footer for backup.
Thanks,
Rick

i think you can pull it fine. HOWEVER - if you decide to put it in the ground, that is where you will stop. get a 8 ft. your 3930 is a fine tractor for its size but you will like the smaller disk.

EXPERT? Well, I'm honored, but I'm not so sure about the expert thing. What I do know about is John Deere's disc measurements. They would consider that a 12'-6" disc. Their size rating is always the width of the REAR gangs. (The widest point) That disc would be a little much to pull in plowed ground, with 45 HP. You are lacking in horsepower AND wieght. You could pull it on untilled ground, provided it's not cutting too deep. I'd say your tractor is more suited for something around 8'. There's a number of things that might effect the "outcome". Disc spacing is one. 7-1-2" spacing would keep the "pounds per disc" # down somewhat. It won't cut as deep, but is a better "finishing disc". 9" or even 11" spacing makes for a better primary tillage disc, but they tend to cut deep, making them pull harder. Wieght of the disc has a lot to do with how they pull. Newer disc's, made in the last few years, tend to be heavier. Higher horsepower tractors are more plentiful nowdays. The disc's are made for them. Just for comparison, I have a 60 HP, 7400 lb, 2440 Deere. I pull a 10'-6" disc with it (normally) I have a 12'-9" disc, with 9" spacing. It pulls like the anchor is out, behind the 2440. The 10'-6" has 7-1/2" spacing. It pulls fairly easy. I try to run at 5 MPH or above. The 12'-9" disc is used for shredding stalks, prior to seeding wheat. I have an old 4020. We pulled a 15' disc with it, back in the day. John

I run a JD #111 disk. I always thought it was rated at 12', but if you include the outside disks on rear gang it measures 14'. These outside rear disks are undersized, I always assumed they where there to level more than cut. Seems to pull fine with the 3020, 3rd gear. Any more info on the #111 would be appreciated.

Those "undersized" disc's are called "furrow fillers". They aren't included in the size of the disc. (per John Deere specs) Measure the rear gangs total width, EXCLUDING those, and that'll give you Deere's sizing of your disc. I have some old sales literature on the model 111. Let me know the number of disc's per gang, and the spacings, and I'll look up what size Deere "rates" that disc as. I'm looking for a 111, from 10' to 12'. Is yours for sale? John

10 disks per gang spaced 7 1/2" apart. This ones not for sale, bought it because it is immaculate; no welds original paint etc. bear getting it home though (I only hit one trash can towing it behind the pickup about 50 miles) in this area most guys are no till and run big offsets, I paid 2000 cash to an old boy who tried running it through clay, he probably ended up with an offset in the long run.

Had the same disk set when I was a kid. Pulled it normally with the Allis Chalmers 190XT with harrow drags behind it. Then finally got a "real" disk for the 190 (16 foot heavy working disk)

But would pull the 12' JD now and then with the Massey Ferguson 50 gas, without duals, over fresh plowed ground was the hardest pulling.

Once the plow ground had been knocked down, she pulled it like a champ.

Wet soil obviously slowed it down quite a bit.

2gangs X 8 disc X 9" spacings=144" total. 144"/12=12ft. 45 PTO HP might be a little light for a 12ft disc like yours. 9" spacings usually are more for a primary type disc, 7" or 7&1/2" spacings are more for a finishing disc. Primary disc usually don't cut real well unless they are cutting pretty deep. You may need to hold it up out of the ground and set the angle of the gangs at near minimum or both like mentioned below. When you do this you won't do a good job of cutting and mixing the soil.

hook on to it and try. if it pulls your tractor too hard then
1. raise the disk a little with the hydraulic cylinder.
2. adjust the angle of the gangs to cut less
3. combination of both.
4. keep in mind that you will need to carry the disk on the wheels to control the depth you want
5. 4 to 5 mph is the right speed. (go fast until the rear gangs are cutting too deep a ridge on the ends. speed helps the disk break the ground up better)
6. watch your temp gauge. don't let it over heat. let it work the tractor without excessive lugging.
7. too much angle in plowed sod ground will bring clumps of sod back up.
8. as you finish up with the disk you will use less angle then when you do your first pass
have fun and good luck
Ron

Rick,
I have also recently purchased a new to me A/C 10' wheel disc.I have a 2wd 40 hp,5200 lb A/C 160 tractor to pull it.In spots it can be a very hard pull in plowed ground running in 3rd gear.I usually have to downshift to 2nd to get through these soft spots,then back into third.The disc pulls much easier on unplowed pasture type ground. I would think that your tractor would be much the same on pasture vs. plowed type ground.The 4wd. and 5 more hp would be a definate help in plowed ground but i would think a disc that size would be the definate upper limit for a tractor that size.

It's fun to guess, it's better to know. I'm guessing
I think you can pull it.
I think it's a 12 ft.
I think it's a BW

I would say it is a 10' disc..

45 Horse is plenty...if you have any tread at all, you won't have any problem.. I pull an Int'l #37 with my WD-45 in 3rd---
anywhere, tho I do use duals... Same size as yours..

We used to pull an international #37 disc with an M Farmall, that is a 4 38" row disc and we had no problem in downed cornstalks.

We pulled an 11 ft.Kruase tandem wheel disk with a Super M. 2nd or 3rd.gear for the most part. Disking corn stalks was fine. Disking plowed ground made for a good pull.You should be able to pull the disk ok.
