The Method of Calculating Ploughshares Durability in Agricultural Machines Verified on Plasma-Hardened Parts

Reliability consists of four components: failure-less operation, maintainability, durability, and preservation ability. For different machines conditions combinations these properties, differences in how they are balanced proportioned essential. tractors, the most important aspect reliability is while for agricultural machines, durability important. Using example a ploughshare, issue increasing has been studied; method calculating ploughshare various types soils described. The use plasma hardening surface 65G-steel proposed; effectiveness soil-cutting parts its economic feasibility have proved. Due to depth 1–1.8 mm, service life increases by 2–3 times; moreover downtime expensive machine-tractor units replacing worn-out reduced.
