Pull Type Disc for a Farmall SMTA

[Brady Miller]

What size pull type disc can I handle with my Farmall SMTA?
 

[Hayfarmer]

it depends upon type of disc, soil and how deep you want to go. I have a 9 foot offset JD disc that is pretty heavy. In plowed ground it was all my SMTA wanted. Tandum discs don't pull quite as hard.

A lot will depend upon soil type & the make of the disc as some discs pulled harder than others. 'Back in the day" we pulled 9' Kewanee discs with our SM & 450. Later bought a 13' IH #37 and both tractors pulled it as well as they did the Kewanees. I think it was mainly because the IH used a ball bearing & the Kewanees used a block type bearing which created more drag.

The very first hydraulic disc on our farm followed a JD 3020. It was an IH 10" #37 3020 was traded for 4020. Disc went to a 47 "M" Gasser. The old gal did just fine in 3rd, but she was VERY thristy. Restored the disc and added drag last year. Old M was sold at estate sale.

That's a nice looking disc! I like the drag.

I don't have hyd on my SMTA right now, but my 13' RWA JD is a pretty decent load for my MD.

I pulled a Krause 13 1/2' with the Super M I use to have without any problem. The only problem is I wish I had it back.

Ive got a 400 and we always had this 210 John Deere disc as a kid that we pulled with a 4010 at least.I got in a bind last year and hooked the 400 to it.I believe its around 14 ft wide.It pulls it great in 3rd gear working up a 4 inch seed bed,not spinning,just walkin and talkin.Its only weighing 7400 with me and wide front,fast hitch and a pair of rear weights.I know it wouldnt do it in plowed ground,but it fooled the he11 out of me

I know guys will argue,but a 10' is the average disc they used.

I bought a 10' #37 IH for my Super M(It measures more like 10' 4"-6" wide)with 16" cutters. It was pulled behind a 400 it's whole life since it was new. In better soil you could probably use a wider disk,but on average right around a 10 footer is what I have seen the majority of them pulling.

In our soil our 47M with a super kit would pull our 10ft IH #470 in plowed ground with a 12ft Case drag harrow behind it all day long.

Didn't put the wings down but mine handled this one pretty good!
