Construction equipment: Mulching head attachment for skid steers

construction equipment Loftness

Utility tools: Building on the success of the previous G3 model, the Carbide Cutter G4 is Loftness Specialized Equipment’s newest generation high-performance mulching head attachment for skid steers. Incorporating an adjustable shear bar to customize material sizing and a 37-percent larger displacement drive motor with more torque, it is packed with features that increase efficiency while maintaining rugged reliability.

The Carbide Cutter G4 is available with 61- and 71-inch cutting widths. All models are offered with either carbide-tipped teeth or and heat-treated steel planer blade Loftness Quadco teeth to match any job applications. The precisely engineered tooth pattern has an improved staggered spiral configuration that offers better power distribution and balance, as well as single-tooth contact with the work surface at all times.

For maximum cutting performance, the Carbide Cutter G4 features a two-stage cutting chamber with two shear bars. This combination of features results in small particle sizes while eliminating the jamming and wrapping issues associated with competitive products. A new adjustable primary-stage shear bar can be widened or narrowed to fine-tune material size and production rate. And the inside of the cutting chamber is smooth and open, which reduces clogging from mud or buildup of material. Improved skid shoes can be adjusted from 0.5 inches to -1.5 inches, which allows mulching below grade.

Operating at 2,000 to 2,400 RPM, the mulching head features a synchronous drive belt for greater efficiency and less maintenance. The G4 comes standard with a V-Drive system that includes a variable-displacement motor (V-Drive) with 37-percent more displacement, which improves torque and offers less stalling and shorter recovery. The V-Drive also has load-sensing technology. Under light loads, it operates at maximum RPM, and as the load increases, it automatically lowers the rotor RPM to maximize torque.

Full rotation of the mulching head is achieved thanks to specially designed hose routing that has been improved to allow more motion without damage. This feature also allows the unit to easily position trees with the adjustable push bar and welded claw hooks. The push bar can be used to push falling brush and trees away from the power unit, and the claw hooks can pull material into position for proper feeding.

The Carbide Cutter G4 is designed for maximum durability. Abrasion-resistant steel is used in areas exposed to high wear, and it comes equipped with a custom hydraulic control valve that protects the unit from pressure spikes. It also stops the rotor quickly on shutdown without damaging components. Other standard features include an on-board pressure gauge and steel deflector chains.

Loftness manufactures the VMLogix line of vegetation management equipment, which includes hydraulic oil coolers and high-performance mulching heads for a variety of equipment, ranging from skid steer loaders to 400-horsepower prime movers.
