Kuhn DOMINATOR 4855-7
Features
RESIDUE MANAGEMENT
Coulters
The Dominator® 4855 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. Solid casting increases durability in rocky conditions. Choose between the 26.5-pound, 7” wing ripper point and the 22-pound, 2.5” straight ripper point.
QUALITY FINISHING
Rear Disc Conditioner
The Dominator® 4855 disc conditioner system is hydraulically adjustable to meet varying surface residue requirements. Front blades are 24" diameter smooth disc blades on 18" spacing and rear blades are 24" diameter fluted blades on 12" spacing to reduce clod size and level soil.
Maintenance-Free Bearing Assembly
Discs feature individual Rock-Flex mounts for protection with rear mounts reversed to shed residue for superior performance even in heavy residue conditions. Sealed, angular contact, maintenance-free bearings and a machine-forged spindle with 5-bolt pattern allowing for fast and easy service.
Heavy-Duty 24/7® Conditioning Reel
Choice of heavy-duty 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.
