All ProCut sections are secured with special serrated bolts. Self-locking nuts ensure a secure and durable joint. The cutouts in the center of the section, help clean out residue buildup and also reduces the weight of the knife. The sections are not chromed. They are painted and have a self sharpening effect.
Chromed sections wear the guards faster and chrome plating is a very hazardous process.
All Schumacher cutterbar knives are manufactured as sectional knives. The sickle bars can be transported easily and can be packed in 7-9 in. segments. The special joint knife allows the sectional knife to perform in the same way as a one piece knife and is as strong or stronger than the original. The guard is made out of high quality spring steel with an extremely hard and wear resistant surface. Because the bottom and top of the guard are bolted to the cutterbar, the guards hardly ever bend and never have the top lip break off, a common problem of standard guards.
