John Deere Coulter disassembly D673A type

A quick how-to on coulter blade / bearing removal from a JD D673A yoke type coulter. This was done on the plow while still attached. Always wear safety glasses and gloves to protect yourself.

So I picked up an old JD 4 bottom 3 point plow with no coulters. how will this turn sod over without coulters ? I was considering buying some 1 1/2 in rod and mounting them in the old clamps and sharpening the edge just to score the sod first , crazy ?

It may work but will likely not be nearly as good as a rolling coulter.

@@tylertheplowguy8690 Agreed but the cost of 4 used coulters is more than I paid for the plow. without them will the plow blades rip the sod and leave a jagged mess ?

Without coulters, your plow will likely clog up often and terribly. The 1 1/2 in rod idea in the old clamps will most likely break all of the old clamps and will clog up. Try finding used coulters at junk yards in your area or put an ad in the wanted adds. Until you find coulters, disk the area you want to plow first or rotary mow and disk to chop up plant vines. I plowed 10 acres the other year. Started with notched coulters on the plow. The notched coulters kept getting wrapped up with vines. I could only go about 100 yards and the plow was clogged up terribly. Subsequently, I rotary mowed the entire field and changed the coulter blades to the plane round type and adjusted the coulters per the book. Went back to the field and no more problems with clogging. The plane round type coulters cut the vines like a hot knife through butter. Plowed 10 acres with the JD 620 in 3rd gear and F145 3-16's. @@ExploringCabinsandMines
