Coulter blades

Glenn D · May 1, 2015

Hi Folks

I have ferguson and dearborn plows that need 13" coulters. I thin they could take bigger but thats whats on there. I se there are lots of different styles wavy, notched and things which are the best to use?

They were originally 15 1/2" in diameter with 18" coulters being optional on some. You could get plain round coulters or the notched coulters for trashy conditions. Here are the ones I buy for replacement on my Ferguson plows. They match perfectly except they are 16" instead of 15 1/2" which have caused me no problems and the rivet holes match perfectly with the hubs.http://www.agrisupply.com/plain-flat-mm-rch-rfh-coulter-blade/p/53513/

Do the notched really work better in trash? and did you rivet your hubs back on ?

Get as big as you can, this is one of those deals where bigger is certainly better!

Smooth work well.

Notched work a tad better in very hard ground, or real wet ground, but the coulter is supposed to cut the side of the furrow and mostly cut trash
like cornstalks, and a smooth plain one is a better cutter in most conditions.

Wavy may pull through mud better by clearing the mud through the arm and get more traction in the mud; but I guess we aren't supposed to
plow if its that muddy, and so......

Call Steve Smith in Ohio he might be able to help with new notched blades.

Yes NOTCHED blades work better in trashy conditions than smooth edge...especially when conditions are dry.

Steve's number is 419-618- zero-zero-17 (disguised number for anti-spamming purposes)

To be honest I have never used the notched coulters. I've always had the plain ones. I didn't rivet mine back on because I was needing to plow when I put the coulter discs on, so I bolted mine back on for the time being with 5/16" x 1 1/2" fine thread bolts. The rivets were 5/16" x 1 3/8" and they are still available from Agco in a 1lb box, part number 800165M91.

I replace the coulter blades on my MF #62, 3x12" plow a few years ago.
I used notched blades, they work fine. I bought the largest blade that would fit in the coulter frame.
about $15 each

Thanks for the info and glad to hear I can get the right rivets too.

This all stared because I couldn't get this plow to work properly i'm still having a hard time with now though. I think I have it all adjustet per the book but the furrows keep closing back over. with the coulters adjusted and cutting it sure takes a lot less power now but if I can't keep the rows open then i'm wasting time.

Glen, your old Ferguson plow may be like mine, you have to drive faster to get the dirt
to flip over and stay there.

These plows have wings with less curve.

Some plows have much greater curve on the wing and will turn the dirt at slower speed.

Also be sure the wings are bright and slick, that also helps.

That's what I thought too but it made its first 2 perfect furrows earlier when I slowed down 1st gear 3/4 throttle (instead of second) but I'm not sure that's the whole story.

Going to try again on some new ground tomorrow and see what happens. I have a suspicious ion it might have to do with how far the coulter is away from the landslide horizontally. Because that's where the ground breaks. Right where it's cut by the coulter. That might vary the height of the furrow wall. Seems these furrows were heavier on top and folded back on their own.

I have to free up that front coulter frame so it can swing it keeps pinching lumps against the side of the point then it clogs. Other than that it worked like I would want it too right then.

Your problem with not rolling over is probably what you are trying to plow. Sod is harder to turn than corn stalks and the older the sod the harder. Then ground type also makes a difference, the more clay the harder to roll it over. Trying to plow too deep is likely your problem. If it is a 14" plow then do not try to plow any deeper than 7" and more likely try 6.5", 12" plow no deeper than 6" and possibly 5.5"

Notched seem to turn better in corn stalks and not plug as much..

You may want to add Moldboard extensions to roll the soil over better..we always used them on out JD and AC plows, along with Landslide extensions also..
All these insure the soil will turn and not roll back into the furrow..

Cover-boards are always a big PLUS and easier to set than Jointers..

Are moldboard extensions made or bought ?

BushogPapa · May 3, 2015

You could make them, most likely were available when the plow was made..
