Until recently, new parts to fit John Deere disk plows today were scarce if any may be found. We now offer new disk blades and new scraper blades (for use on moldboard type scrapers). See below for more information.
Disk Plows are different from moldboard plows in that a large diameter disk is used to engage the soil. Most often they were popular in areas where a moldboard plow would not operate very well. Disk plows work best in dry and hard soils which moldboard plows would not easily penetrate. They were also popular for use in sticky soils such as gumbo. Disk plows were also used for ‘new ground’ where stumps, roots, and stones where other tillage methods wouldn’t work well.
John Deere produced disk plows in sizes from 1 to 6 disks and in different configurations. Older plows were typically drawn or pull-types. Larger plows were often meant to be pulled by large track type tractors or dozers. In the 1940’s Deere offered integral and semi-integral to the tractor. Some were specialized for use in terracing while others were used for general tillage. In the 1950’s as 3 point hitches gained popularity in their tractor line, Deere offered a few models ranging from 2 to 4 disks in size. Disk plows continued into their tillage line up until the 1980’s before being phased out.
Disk plows are often confused with disk tillers. Disk plows have one or more disk blades held individually by a standard and bearing assembly. Disk tillers have one or more gangs of disks on a single spindle or bolt held by two or more bearings. The gang or gangs is held at a diagonal to the direction of travel as to turn the soil over once in a single direction. In some areas disk tillers are referred to as ‘one-way’.

Replacement Disk Blades for John Deere Disk Plows
Long obsolete, anyone who uses a vintage Deere disk plow will appreciate availability for new disk blades. They directly replace original part number A14557 (plain) and SD2041A (notched) which was used on many models of John Deere disk plows. Made from 5 gauge (.236 thousandths) boron steel these 26 inch disks are long wearing and have been heat treated. These disk blades are engineered to match the original design and shape in every way possible (including the correct concavity and overall shape) and were produced only for John Deere Disk Plows; they’re not a repurposed disk harrow blade. The blades are drilled in the exact John Deere 5-hole pattern and include countersunk plow bolts to attach them. These blades will fit on nearly every Deere disk plow made aside from the M6/ MT6 series which can only accommodate 24” diameter.
Our new replacement blade for original part 16604A $35 each (includes 2 bolts for attaching to the shank)
See original moldboard type scrapers installed on a model 472 disk plow.
This scraper was used on many different models of John Deere disk plows including: 472 475 802 803 805 300 400 500 600 120 100.
This scraper blade/ moldboard is a reproduction for original part number 10664A and will add a lot of 'CLASS' to your vintage JD disk plow. This part was used as optional equipment on nearly all John Deere Disk plows (both pull type and 3pt hitch).
Most originals are missing, heavily worn, or rust pitted beyond fixing.
These moldboard scrapers will fit as good as or better than the originals. The trick is adjusting the moldboards with at least 1/4th inch of clearance between the blade and scraper to keep wear to a minimum. Ideally the adjustment so that the point of the scraper fits closer than at the blade edge so trash can work its way out rather than clogging.
We offer the scraper blade only at this time. To use this scraper you must have the mounting clamps and the arm to which the blade bolts.
Missing a rear wheel scraper blade or blade assembly from your JD 472 475 802 803 805 or F225 Disk Plow? Here is the solution. $35 each per complete assembly or $12.50 for a new scraper blade with rivets. This is an essential part of a good working disk plow and absolutely necessary in wet and sticky soil conditions.
Using John Deere disk plow is a real treat. Be sure before purchasing a disk plow to find one with scrapers. Disk scrapers ensure a good job of plowing leaving the field neat and as level as possible. The photo to the left is a model 803 and isn't for sale.
