The 20 Point Crumbler Wheels close the seed slot much better than the factory smooth wheels, especially in no-till conditions. They are 1/2″ wide and feature 20 rounded teeth to crumble the seed slot closed. They install on the early 750 drills, up to serial number 003834. The wheels are made from long-life heat-treated T1 steel and they often last for over 15,000 acres on 15′ drills, which is 2-3 times more than the life expectancy of cast closing wheels.
The 20 Point Crumbler wheels for 50 series come with an assembled heavy duty hub with a long life Peer SeedXTreme bearing. There is no need to replace the arm as the SeedXTreme bearing lasts many times longer than the factory tapered bearings. The 20 Point Crumbler Wheels for Early 750’s utilize the existing 5/8″ bolt and nut, but come with everything else required.
