DESIGN AND ANALYSIS OF COST-EFFECTIVE COMPACT DISC HARROW

It is well-known that during tillage operations suprising items may appear below the soil surface in agricultural lands. Sometimes a stone/rock or solid root can cause major damage to equipments. These rocks and roots impacts on equipment. In order eliminate minimize impact of these forces, shock absorbing equipment used provides connection between disc harrow chassis. The most commonly material for absorbers rubber-based polymer known as vulkollan (polyurethane), which has wide are use industry. Vulkollans absorb wear out over time because sun, climate impacts. Therefore, this experimental study, steel springs since they much more durable. Modal analysis was conducted investigate mechanical properties springs.
