Description

• The cutting and soil turning action of the Tandem Disc Harrow varies with the diameter, weight and concavity of its blades, blade spacing and the angle of the Disc Harrow gang relative to the direction of travel, and the operating speed
• Can help prepare overwinter stubble or prepare the land for seedbeds in dry land farming
• In a mulch-till system that includes soil-structure improvement as part of de-weeding of lands, a Tandem Disc Harrow with adequate disc spacing could create a seedbed for a winter cover crop by partially incorporating harvested stubble knocking the stubs down and covering the crop residue creating a rough seedbed of overwinter residue
• By managing plant residue, organic fertilizer will be increased in the soil and rain water will penetrate the soil easily
• The Tandem Disc Harrow can also run shallowly before planting to eliminate surface weeds and prepare seedbeds
• The bearings are heavy duty ranging from flange-type bearings to grease-housing bearings
• The gang shafts are high tension steel and the cast iron spacers are robust
• The disc configuration is scalloped discs on the front gangs and scalloped discs on the rear gangs
• The disc sizes vary from 510 – 610mm. Tandem disc gangs are configured with the front gangs left and right, lead with the outside ends ahead and angle back toward the centre
• The back gangs are in the mirror position; have the inner ends leading in the centre of the tool and outside ends angling back
• Gang angle is fixed at 18? or 20?, or adjustable at lesser angles
• Half Tandem Disc Harrows are also available. The gangs are configured to cut contour lands and smaller fields enabling the implement to turn with ease
