Överum plows are designed to ensure high plowing quality, easy adjustment, and cost efficiency. All of this is based on many years of experience in plow development, making Överum plows stand out in a class of their own. Durable frames, made only from the finest raw materials, guarantee a long service life and maximum performance.
Överum achieves a high strength-to-weight ratio through the use of heat-treated, hardened steel. Frame tubes made from HRM 500 steel have a 40% higher yield strength than standard frame tubes. The profile has high resistance to bending and can withstand large loads.
The modular design with bolted connections offers many advantages. Worn or damaged parts can be easily replaced. Precision drilling ensures a perfect fit. Överum produces plow beams designed for extreme conditions. The heavy-duty beam, with an 80 cm clearance, features cast steel legs with increasing material thickness where the stress is greatest. The leg profiles encase the beam in a U-shape, providing additional strength.
A simple and logical adjustment system makes it easy to set up the plow for minimal traction requirements. This results in optimal plowing performance and the lowest operating costs.
Separate adjustment screws for the right and left height settings simplify the basic setup. The turnbuckle on the side of the frame influences the alignment of the plow body. It is used to balance all lateral forces, ensuring the plow follows the tractor with ease. The width of the first furrow is adjusted with the cross screw or cylinder. The same logical adjustment principles apply to all models of Överum reversible plows.
ÖVERUM Mucro is the name of the heat-treated steel used in ÖVERUM wear parts. The raw material is carefully selected and heat-treated using ÖVERUM’s proprietary process. The correct carbon content in the steel profile determines the characteristics of the moldboard. The moldboard blanks are treated for 24 hours in a furnace with a carbon-rich environment and high temperature. The carbon then penetrates the surface layer of the steel. The subsequent heat treatment gives the surface layer hardness and wear resistance, while ensuring toughness and impact resistance at the core of the moldboard.
Heat treatment brings out the best properties of steel
Drawing on over 350 years of experience with steel and in close collaboration with Swedish steel suppliers, we have developed our own special hardening methods. The moldboards are treated for 19 hours at 900°C in a furnace with a gas mixture containing an excess of carbon. The carbon content increases on the surface of the steel, while the core remains unaffected. During subsequent hot forming and hardening, the surface becomes very hard, while the unaffected core retains its stress-absorbing toughness. The correct carbon content in the steel profile determines key properties of the moldboard. The carbon enrichment in the surface layer and an unaffected core result in a combination of toughness in the center and hardness on the surface, which is 65% higher in Överum's original moldboards compared to boron steel.
