Kuhn DOMINATOR 4857-9
Features
Residue Management
Coulters
The Dominator® 4857 coulter module features ultra-large 25" diameter coulters on 9" spacing for improved residue cutting versus discs. An innovative live hydraulic down pressure system allows the operator to set down pressure to match conditions. With constant down pressure the coulters automatically seek the depth that provides optimal cutting resistance. Coulter gangs are mounted with Rock-Flex™ bearing arms for added protection. Coulters feature PEER® TILLXTREME™ maintenance-free bearings.
Shank Spacing
A split-the-middle shank pattern is achieved with two ranks of shanks on 18" spacing, none closer than 36" on the same beam. This provides maximum soil fracture and non-stop operation in heavy residue.
Fracture
Shanks
Choose from all deep-till parabolic shanks, a combination of deep-till and heavy-duty chisel shanks or all heavy-duty chisel shanks, depending on your agronomic needs.
Double K® Points
Double K ripper points double the wear life of prior KUHN Krause Dominator fabricated steel and carbide-capped ripper points. Choose the 7” wing ripper point for optimal fracture or 2.5” straight ripper point for reduced draft.
Quality Finishing
Rear Disc Conditioner
The Dominator® 4857 reverse-tandem disc conditioner system is hydraulically controlled to meet varying surface residue and leveling requirements. Front blades are 24" diameter, fluted disc blades on 18" spacing and rear blades are 24" diameter fluted blades on 12" spacing with center-mounted 4-lobe feathering blades to reduce clod size and level soil. A specially designed C-arm now allows for the disc hub to be directly mounted. This new combination of C-arm and hub provides 10% more soil and residue flow through the disc conditioner to improve continuous operation in adverse conditions. Dual hydraulic cylinders control the position of the rear disc conditioner for optimal operating height in relation to the tilled soil surface.
Maintenance-Free Bearing Assembly
Independently mounted blades on a 6-bolt hub containing double angular contact bearing equipped with 11-lip seals offer outstanding reliability and maintenance free operation.
Heavy-Duty 24/7® Conditioning Reel
Choice of heavy-duty solid round bar or heavy-duty flat bar reel with Peer® TillXtreme™ maintenance-free bearing assemblies mounted on heavy-duty ductile cast bearing arms provides aggressive clod sizing and soil firming. Optional hydraulic lift available.
