Plow Coulters play a vital role when it comes to John Deere moldboard plows! They serve two main functions. The first main function is to cut any crop residue ontop of the ground so that it may be turned under by the plow bottom without hanging up on the bottom or standard. Secondly, the coulter opens a slit in the ground which leaves a clean furrow wall that looks like your plow cut the soil like a knife rather than having torn the ground leaving ragged edges.
New Blades for Coulters are what we offer.
Your complete John Deere coulter with our new blade installed.
This coulter blades is just like the orignal part 33132A, which was offered by John Deere as an optional blade when new plows were ordered. These blades are made from high quality boron Steel and are heat treated to ensure long life and ruggedness you would expect in your plow. The center hole is 2in across with the 6 rivet/bolt holes on the JD 3-1/2in pattern. They will work with both 3 and 6 hole hubs. The blades cost $35 each. (Rivets available as extra if desired)
Repalces OEM part: 33132A, 23842A , replaces blade only in DA6732A
If the 17" notched blade doesn't seem right for your plow (whether it's how the blade looks or if you're worried about clearance under the plow frame), the 15" plain edge blade replaces the original Standard Equipment offered by JD for all coulters unless optional blades were ordered. They are made from the same high quality boron steel as the 17" blade above, but without notches. The center hole is 2 inches O.D. and the 6 hole bolt/rivet pattern is aon 3.5 inch center to center.
They cost $30 each. Rivets are available for additional cost if desired.

Coulter blade/bearing adjustment is fairly simple.

Knowing the part names of your coulter is important when asking for parts. While there are other types of coulters dependent on the model type of JD plow you have, the ones illustrated above are by far the most common. Tyler only offers new coulter Blades; any of the other parts are subject to availability of used parts. Most often the bearing hubs/cones are usable even when worn so long as they aren't chipped, cracked, or broken.
Adjustment Instructions for High Speed Coulters from the 810 series Operator manual.
Coulter Adjustment Instruction from No. 52 Plow manual. Gives tips depending on field conditions; i.e. Sod versus Stubble.
See the above illustrations on coulter adjustment. This adjustment is VERY important to doing a good job of plowing. If your coulters are pushing trash ahead of the blade either the blade is set too deep or the blade is worn down too small to do good work and needs to be replaces. For top performance, sharpen your coulter blades as the instructions say; but heed caution around sharp blades to avoid being injured.
