Designed for Your Work
The EHDW-4220-14 robust designed for the contractor is needs deep plowing in heavy trash conditions with large 4WD tractors. This heavyweight disc harrow has no other contenders in the same class.
The front single lip Category 4 hitch requires the tractor to have a hammer strap drawbar. This will enable operators to attach a safety tow chain from the drawbar, securely to the disc harrow. The front pole hitch can even be rotated back parallel to the Gang Frame for reduced shipping footprint on rear gooseneck trailers.
The main frame is made from large high strength steel 9″ x 6″ x 1/2″ steel tubing.
The gang tube is constructed from 10″ x 5″ x 1/2″ steel tubing.
Oil Bath Bearings:
Heavy duty gang beams feature welded gang standards specifically designed with Oil Bath gang bearings for long service life and less downtime in extreme conditions. The larger tapered roller bearings and duo-core type seals are enclosed within a rugged ductile cast iron housing assembly to withstand extreme conditions. A heavy-duty steel rock guard plate protects the housing assembly. Competitive models with greaseable bearings are more susceptible to seal damage and shorter service life due to over greasing.
Made from ductile cast, the spools offer superior durability against rocks. The ductile castings have thicker sidewalls than any fabricated spools on the market. Many competitors add weight exclusively to the main frame in order to increase mass for better blade penetration. Conversely, our ductile cast spools provide the additional weight where it is needed most – centered right over the bearings. This dramatically reduces bearing side loads when operating on uneven ground as compared to competitive models that put the weight above the gang. The EHDW-4220-14 ductile cast spools are machined on both ends to provide the perfect fit to the disc blade. This provides the greatest clamping force between all surfaces. Additionally, each end of the cast spool is a different size so they offset the stress concentration areas on the disc blade.
The EHDW-4220-14 is 11’-7″width for easier permitting over width loads. The front pole can be rotated to the side to reduce the overall length when transporting on trailers. Packing a lot of machine into a smaller footprint.
