A Study on Plowshares Wearing Behavior under Conditions of Sandy Loam Soil

The wearing behavior of three different plowshares a, b and c with different hvn vickers hardness number 417, 363 and 320 hvn was experimentally investigated. the experiment was conducted in sandy loam soil with 8 and 11% moisture contents. wearing rate, wearing resistance, critical wearing value, specific wear and share expected life were determined as a function of change in share position (front and rear), soil moisture content and working time. the obtained results have revealed the following: • share expected life increased while wearing rate decreased by increasing share surface hardness. • share expected life was higher while wearing rate was lower for rear share compared with the front share. • increasing soil moisture content from 8 to 11% decreased share expected life for the three experimental shares
