Loftness Carbide Cutter G4
|
The new Carbide Cutter G4 has taken the proven performance of its predecessors to another level. Built in North America, the G4 has a refined and balanced design that makes it the standard by which all other mulching head attachments are measured. This newest generation incorporates features that make it a more durable, efficient and versatile vegetation management tool, including an improved and smoother interior body shape that decreases drag and helps prevent buildup of mud and other debris. |
|
The efficiency behind the Carbide Cutter G4 can be found in its two-stage cutting chamber. Material that enters the spinning rotor (clipping at 2,000 to 2,400 rpm) is forced through moving carbide teeth and the primary shear bar. New for the G4, the primary shear bar has been made adjustable so the clearance can be narrowed or widened depending upon the desired material size and production rate. From here, the partially reduced material passes smoothly to the secondary cutting chamber behind the front bumper, where it’s processed further before being discharged toward the ground. |

Design Innovations That Put You On The Cutting Edge Of Performance
|
|
Material that enters the spinning rotor is forced through moving teeth and a new, adjustable primary shear bar, the clearance of which can be narrowed or widened depending upon the desired material size and production rate. This partially reduced material then passes smoothly to the secondary cutting chamber behind the front bumper, where it's processed further before being discharged toward the ground. |
|
The positive drive, cog belt and sprocket design increase efficiency and require less maintenance than other drive types. |
|
Skid shoes on the G4 now adjust from 0.5 inches to minus 1.5 inches to allow for mulching below grade. |
|
The rotor ends are machine turned to mate with close tolerance, machined anti-wrap rings, resulting in minimal debris in the bearing chamber. |
|
Complete with welded claw hooks, this bar can push falling brush and trees away from the power unit, or pull them into position for proper feeding into the head. |
|
An improved staggered/spiral tooth pattern assures single-tooth contact with the work surface at all times, as well as optimal balance on the rotor. |
|
Body components are laser cut from premium strength steel to assure the utmost in rugged reliability. Abrasion resistant steel is used in high-wear areas. |
|
Spinning at 1,600-2,000 RPM, the G4's rotor is 17-inches in diameter with 2 3/16-inch bearings, and features robotically welded, forged steel knife holders. |
|
To keep flying debris at a minimum, steel deflector chains run the entire length of the attachment. A built-in hydraulic braking system quickly brings the rotor to a stop at shutdown. |
|
An on-board PSI gauge monitors the load on the hydraulic system, which enables the operator to get peak performance out of the G4 attachment. |
|
The G4 can attach to any skid steer thanks to a universal mount. |
|
A lower profile improves visibility for the operator, thus increasing safety, productivity and efficiency. |
|
Incorporates a system high-pressure relief valve to protect from pressure spikes at the source. Also includes an anti-cavitation shutdown circuit. |
|
Improved on the G4 with shorter hoses that reduce the chance of binding, yet allow for full range of motion without damage. Hoses are included (no couplers). |
