Agricultural machinery parts are the high-wear metal components that till, plant, fertilize and harvest your soil—tines, plow points, seed-metering discs, cultivator shanks, mower knives and more. They decide how long your machine stays in the field before the next service stop.
Plow point tip – abrasive soil erodes 2–3 mm per 100 ha.
Cultivator tine heel – impact + bending causes fatigue crack.
Seed disc edge – micro-chipping from sandy loam.
Bolt hole collar – fretting wear loosens the fit and breaks bolts.
