Built with alloy-steel construction, replaceable pin-on teeth and zinc-plated, pivot pins with protect- ed Zerks, these attachments can ruggedly resist impact that any ground materials provide. Another key feature is a weld-on "D" ring that expands the list of job site tasks these root rakes can tackle, such as pulling brush in forestry applications or scrap on a job site. "The root rakes are exceptional addi- tions to our line of Worksite Pro attach- ments that increase the productivity of any compact machine being used in job site prep applications," said Gregg Zupancic, product marketing manager, John Deere Construction & Forestry. "We designed this line of root rakes to be a tough solution, ready to take on any terrain in its path." The root rakes are available in 72-in. (RR72), 78-in. (RR78) and 84-in. (RR84) width for maximum productivity. The height and width of the root rakes also help shield the fronts of the machines, protecting against damage from large piles of brush or jagged scrap. With the universal, self-cleaning Quik- Tatch easy attachment system found on all John Deere skid steers, CTLs and com- pact wheel loaders, the machine can eas- ily add and remove the root rake in no time. The new attachment is also backed by John Deere parts, service and warran- ty coverage. Like all Worksite Pro attachments, the root rake is also compatible with many competitive models. Loftness Carbide Cutter G4 High Performance Mulching Head Attachment Building on the success of the previ- ous G3 model, the Carbide Cutter G4 is Loftness Specialized Equipment's newest generation high-performance mulching head attachment for skid steers. Incor- porating an adjustable shear bar to cus- tomize material sizing and a 37 percent larger displacement drive motor with more torque, it is packed with features that increase efficiency while maintain- ing rugged reliability. The Carbide Cutter G4 is available with 61- and 71-in. 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 pre- cisely 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 asso- ciated with competitive products. A new adjustable primary-stage shear bar can be widened or narrowed to fine-tune ma- terial 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 to minus-1.5 in., 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), which improves torque and offers less stalling and shorter recovery. The V- Drive also has load-sensing technology. Under light loads, it operates at maxi- mum 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 posi- tion for proper feeding. The Carbide Cutter G4 is designed for maximum durability. Abrasion-re- sistant 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.
