 Topic: Another Disk Width Question
Posted: 07 Dec 2020 at 10:44pm |
Is there a snowball's chance in heck that a healthy WD or at least WD-45 could pull a 11.5' IH #37, 370, 470, etc. type disk? These disks aren't that heavy compared to some from what I've read. I understand that everyone's ground is different, so with that caveat and the fact that I wouldn't be disking plowed ground or going more than maybe 4" deep or so, and my fields are basically flat... Has anyone done it or should I pass on this disk?
I'd prefer a 10' but I have a line on this 11.5' disk in nice shape and figured if I can get my WD or WD-45 to barely handle it for 10-15 acres a year, I'd have a disk I could use if I upsize to a bigger tractor in the future. It has fold down wings that I could remove to use the main disk frame at 11.5'.

I have a 14' straight frame #37 McCormick (IH) disc that I pull with my WD45. At 14' it was all it could do to pull it at a 2" depth. I took the outside 2 disc blades off of each gang, making it about 9.5'. 3 passes over plowed ground,progressively increasing the aggressiveness of the cut, and it is almost as good as tiller. (I raise market pumpkins, so, plant by hand). Only downfall is the weight box is at the back, so, the front doesn't cut as well. Otherwise I am happy with it.

As with any implement: proper adjustment make it pull easier. An improperly adjusted disc will pull harder than a mal-adjusted plow and sometimes worse than a living Oak tree. Also if you use a traction booster hitch on the disc behind a WD, you'll think that you have a WD45. I have this traction booster linkage for a wheel type disc available.

If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

Have a 14' model 37 IH disc. Always pull it with the 185 but pretty sure either 45 would handle it. May have to put the right cylinder on it next spring and give it a try.

I wish my memory was a little sharper, We pulled a 13.5' Allis Chalmers disk with our 45. I do not remember the model number of the disc. We had duals on the 45 and the inner tires were filled. We had no trouble pulling it in S. Minn. soil. That was over 50 years ago, where did the time go? Merry Christmas to all !

Thanks all for giving me hope. I sure hope I can avoid using duals but that wouldn't be the end of the world. PaulB, I had actually thought about rigging something up so I could connect the lift arms and get some weight transfer - but taking a couple of outer disks off might be cheaper if my WD ends up not quite being able to handle it.

I think you will find yourself up a tree on pulling that! an 8' is bout the limit. I hooked to my krause 12' and as soon as it hit the ground---instant spin-out. going downhill chicken scratchin it works half azzed but I only did an acre so no big deal.---15 acres a year??? I wouldnt do it. Also some disks pull harder than others.

The Krause discs are heavy. The #37 McCormick is a lightweight finishing disc, so no comparison.

I think you would be fine with a 37 or 370, but the 470 looks like a much heavier frame which I wouldn't suggest. Growing up, we had a 12' IH disk. Never saw a model # anywhere on it. It was quite heavy with dual wheels on it-much heavier than the AC 12' disk we had. It also had the attachments for wings though we never had wings on ours. It would work the 80hp Oliver 1750 pretty good. Never saw or ever even heard of the WD45 trying to pull it and after seeing how hard it worked the Oliver, would have never thought to try it myself. Googling IH disks, the 470 looks like what we had. Our neighbor also had a 12' IH disk but it was visually lighter than ours, with single wheels, and no mounting visible for wings. Looked more like the 370 seen in google pics and way more comparable to our AC 12' disk which the WD45 had no problem with. HTH

Put a 170 govenor spring on your WD and it will liven her up. The guys at R&M equipment had me do this on dads WD45. And they run down the road faster too.

By golly there is more difference between the 370 and 470 than I originally thought. From what I can tell in the parts catalogs duals were a recommended option on the 470. The 370 mentions "well over 200 pounds per foot of cut" but nothing about the 470, other than it's "the same basic design as the 480" which has "over 250 pounds per foot of cut." Seems like the 480 is heavier than the 470 from what I am gathering.
Anyhow, lots of computer reading going on here with no actual field testing, but I'll take a look at this disk in person this weekend and see what I think. I confirmed it is a 470. It does at least have a ton of angle adjustments so it could be set pretty straight.
I'm getting a little off-color here but I came across this really neat scan of a 1970 IH Farm Equipment Buyer's Guide. The disk harrows start on page 26 but the full line is in there. It's definitely worth looking through in your free time:

If this weeks nice weather would have held out one more day we would have had an answer to this question. Going to rain/snow here today and I'm not changing that cylinder and braving the elements. Next spring will have to be soon enough.

John, My gut says no. But if your 45 is fresh and stout and maybe with duels maybe?? Just my 2 cents. I remember the day our Ford 5000 had issues and we hooked one of the 45's on to the disc. Cant remember the size maybe 12 foot? Any way thew 45 tried its best but those were just too much for the Allis. No duels and well warn 45 too. That was on plowed ground. I was think 8 footers were about right for the 45? Maybe flat non plowed ground might work Ok? We need pictures! Regards, Chris |

Going to be champing at the bit all winter now! Or I'll forget completely by the time the frost goes out. Snowed about 4" here overnight, (after it rained all day) I think tillage is done for this year. I have a 7' model 200 AC disc, 45 pulls it in third gear like it's not even back there. This disc was cut down, Amish gut pulled it with horses.

Chris, if this B can pull an 11' Kewanee an inch or two deep, surely my WD can pull an 11.5' IH 470 disk an inch or two deeper? 
This is one of my favorite videos of all time, I think. Regardless, I don't have my hopes too high. If this disk looks like an anchor when I take a look at it I'll pass.
Mike, don't you hate it when winter gets in the way? That's one of the reasons I didn't stay in Iowa.

John, I do hate it, but not completely. Sometimes it's nice to relax a little.
Growing up Dad had a 10' kewanee very similar to the one in the video. Pulled it mostly with the 175 but did pull with the Farmall 300 some too. That 300 was the most anemic red tractor I've ever been around! Grandpa's WD would work circles around it on half the gas. Or so it seemed.

True. It is nice to be forced into a break sometimes. I actually watched a video of a 350 pulling a 13' IH disk and that helped give me enough confidence that my WD has a shot at pulling this 11.5'... Looking at the stats I think I'd take a WD over one of those, too!
I just got home with the disk. It's probably a 17' since the wings are about 3' long. One of the wings is welded up, but I could care less as it looks pretty solid and I'm just pulling the wings off for spare parts anyway. 7.5" disk spacing and they're all in pretty good shape, and the bearings feel tight and smooth. It doesn't have a cylinder so I ended up coming home with it for $750. That might be a little high but this one's just way nicer than almost anything I've ever seen at a farm auction - and especially worth it if I don't have to spend time and money replacing bearings and disks in the near future.
Now will my WD pull it for finishing a seed bed, or will I need to buy a bigger AC tractor? Hopefully we'll find out next spring/summer.

You are going to know when you get there. Soils, hills, wet/dry, duals, weights on disk, or tractor all add up. If it won't pull it like you think it should then reduce the angle of the cut, make shallower passes or you could take a couple of the outside blades off, put in washers and make it more narrow yet. If none of that works, sell it or buy a bigger tractor...

I'm afraid you will have traction problems. Even just the base disc is too much for a 45. Add weight or wider tires or duals and you will still be short a couple of ponies to do a proper job of discing. Having said that, the best way many people on this site solve a hp problem it to buy a larger AC. A 170 or 180 gasser would pull your new disc. They are reasonable. I honestly think you will be dissapointed. Sorry. LeoN B MO
