ADI Agricultural Machinery Parts ADI 900

What are Agricultural Machinery Parts?

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.

Where do they usually fail?

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.
