This was the product that started it all; The 17 inch notched coulter blade. This blades matches OEM coulter blades exactly in shape, size, and even better steel quality. They can be used on nearly every John Deere Plow made from 1936 through the 1970's that utilize either a 3 or 6 hole pattern. The center hole is 2in OD with the rivet/bolt holes on a 3.5in center-to-center size. Replaces original JD part number 33132A. Price is $35 per blade.
The Notched Trash Board is an item that was original equipment, but was made obsolete long ago by a newer design making locating new boards of this type & style next to impossible. The boards (sometimes called Coverboards) are made from AR400 steel and will provide a long wear life all the while looking just as the originals. Don't just replace one as it will make the other trash boards on your plow look worn out. Replaces OEM part number AA10997. Price is $30 each (mounting bolts included).
These will fit JD plows with factory trash board brackets. If you need brackets just ask as we usually have some used original castings available. It is important to note that there were different cast brackets used to fit different types of bottoms. Learn more here...
Moldboard extensions were offered as optional equipment on most John Deere plow bottoms (from the mid-1930's through the 1970's). The moldboard extension attaches to the outer wing of the moldboard by using the two bolt holes & plow bolts made into the moldboard. The intended benefit of the extension is to 'extend' the turning ability of the moldboard to ensure a complete turning of the furrow slice when plowing at slow speeds, when plowing up hill, and when plowing hard to turn soils and in sod. Made from high quality Abrasion Resistant AR400 steel, these moldboard extensions will wear very well and enhance the plowing ability of your John Deere plow. Replace OEM part number 7750A. Price is $30 each.
We NOW have the left hand version of this extension availble for two-way or roll-over plows. Replaces part 7749A. Price is $40 each.

Tyler gets requests for new moldboards and shares for this type of plow bottom nearly ever day. Unfortunately new parts such as these simply aren't available. There are occasionally some New Old Stock items that turn up, but only rarely. Some used parts are available on a limited basis. Tyler has a few shares in usable condition along with some reproduction landsides (limited supply).
The two options for dealing with worn-out conventional plow bottoms is to locate good usable used parts or simply switch your plow over to newer style HS or NU series plow bottoms. It was quite convienent that JD used the same 4 bolt pattern on their traditional conventional plow bottoms as the HS and NU series which replace them so bolting newere style bottoms on an older JD plow is usually no problem at all. Tyler usually has a good supply of replacement HS or NU series bottoms available. For more information on identifying your plow bottom see the Identify my Plow Bottom page
Moldboard plowing was historically a farming practice that was slow and tiresome. Other manufacturers had already offered newer style plow bottoms which were less expensive to repair/replace the wear parts and by the early 1950's John Deere was playing catch-up. The old style plow bottoms with thier 3 piece bottom design (Share, Moldboard, Landside only) was built to suit the needs of farmers that began with Horses and moved to slow moving tractors, but as horse power from tractors increased so did the need to move across more acres faster. The HS series plow bottom was available from 1953 through 1969 before being replaced by the NU or New Universal series plow bottom.

The NU series bottoms were introduced for the 1969 Model Year. The wear parts were 5/16" thick versus the 1/4" thick moldboards and shins of the HS series plow bottoms. The competition was going heavier and faster so JD had to follow suit. For more information on identifying your plow bottom see the Identify my Plow Bottom page
