5-shank subsoiler SUM & SUH series

7-shank9-shank3-point hitch

New Holland SUM medium duty and SUH heavy duty subsoilers are extremely versatile. Developed with features to enable them to match all soil types, simple adjustments allow efficient operation in widely varying conditions and can work directly into land following crops with high levels of residues. All models feature a leg with a reversible tip, a pair of adjustable and detachable side blade clod busters and a clod splitter to improve soil shatter. Working depth is accurately controlled by twin rear 220mm diameter spike rollers with an adjustable tilt angle. This enables the finish to be adjusted to suit the soil and conditions. Heavy soils will be left level and clod free, lighter soils with an open surface less liable to capping in adverse conditions. SUM models can be set to work at depths of between 200mm to 500mm. SUH models are designed to work between 250mm 550mm. Looking after the subsoil the New Holland way SUM and SUH subsoilers form an integral part of the New Holland approach to minimum tillage. Designed to improve the structure of soils by loosening soil both vertically and laterally in the root zone, the rear rollers aid the incorporation of crop residues into the topsoil to boost soil organic matter. A key to the effective subsoil loosening ability of SUM and SUH subsoilers is that the leg breaks soil from below without inversion. Further loosening by the adjustable lateral wings helps to ensure air and moisture can penetrate through the soil across the entire working width of the implement. The lateral wings eliminate the unworked banding of soil associated with more traditional subsoilers.
