Overview
Maximum Subsoil Fracture
Residue management, soil tilth and level soil surface area are all key factors in yield potential. The Dominator 4857 meets this challenge and outperforms competitive tools. Working widths range from 10'6" to 19'6".
The new KUHN Krause Dominator 4857 boasts product features designed to provide optimal compaction removal and residue handling while reducing maintenance time. The double rank subsoil shanks mounted on narrow 18" spacing deliver maximum subsoil fracture. The new reverse-tandem rear disc conditioner produces consistent soil leveling and residue incorporation for pass-to-pass uniformity, while the soil conditioning reel provides final clod sizing along with seedbed soil firming. Maintenance-free features are incorporated throughout the Dominator 4857, reducing the required daily lubrication service time, placing you in the field sooner and increasing operator productivity. Working widths range from 10'6" to 19'6" and models are available with 7, 9, 11 or 13 shanks.
Features
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.
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.
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.
Equipment
Smart Soil Technology
Available as an option on all Dominator 4357 / 4861 models, this ISOBUS control system (SST) delivers in-cab electronic control and convenience for operation and adjustment of machine depth, coulter pressure, disc conditioner depth, and conditioning reel from any compatible ISOBUS display. ISOBUS equipment certified by the AEF is included in the online database. The customer can verify compatibility of ISOBUS functions between the machine and the terminal to be used.
Guardian Hitch
This exclusive option guards against stress on the tractor drawbar and implement frame. Lateral drawbar forces are transferred through the hitch pivot where shock load from steering input is dampened by urethane blocks. Choose from the articulating ball Cat III, IV, or V double-bolt, cast hitch, depending on the model.
Tractor Interface Center
The tractor interface center prevents hydraulic hoses from binding in turns and adds operator convenience. Includes hose routing chart, colour-coded hose grips, storagefor light hookup, and owner's manual.
Single-Point Depth Control - Standard
Shank depth is controlled conveniently with the crank-adjustable depth stop located at the front of the machine. View working depth on the easy-to-read scale.
Heavy-Duty Walking Beams - Standard
Standard on the center section of all Dominator models, heavy-duty 8-bolt hubs with slip-in wheel spindles secured by a single bolt ensure durability and easy maintenance.
