First manufactured and marketed by Gradall before it was acquired by JLG Industries, the G6-42P was recently rebranded as JLG and integrated into the JLG-brand telehandler line. Although the unit shares many of the same design philosophies as the JLG G6-42A, the G6-42P is unique to the industry. The machine’s distinctive 90° pivot-steering axle configuration and its bright blue color set it apart.

The rear-pivot design keeps the outside turning radius at only 171 inches and allows for the load to be carried inside the turning circle. The G6-42P has two- and four-wheel drive modes. The front axle on the G6-42P is a rigid, high-bias limited slip differential design that is supplied by Carraro. Independent hydraulic drive motors coupled with Fairfield torque hubs power each rear wheel. In normal mode, only the front axle is powered. On the floorboard of the cab, a separate traction control pedal engages differential axle lock. When depressed, it splits the oil flow between the front and rear axles. 

The Rexroth-supplied hydrostatic transmission works within one drive speed/range and is powered by a 99-hp John Deere 4045T turbocharged diesel engine. Another feature of the hydrostatic drive is the ability to de-stroke the pump. De-stroking the pump allows the operator to inch, or feather, the drive with the use of one pedal. It also allows the drive speed to be regulated independently from the engine speed, which will allow maximum auxiliary flow.

In the cab the lift-lower/telescope and frame sway/fork tilt are operated by two right-hand controls while auxiliary hydraulics are controlled by a standard left-hand joystick on the dash. The design allows the operator to run lift/lower and fork tilt and control auxiliary simultaneously.
The G6-42P has a fairly long 130-inch wheelbase and a low center of gravity, which translates into greater lifting capabilities and added stability when carrying a load over rough terrain. Without outriggers, the machine lifts 6,000 pounds to the maximum 42-foot lift height and 1,300 pounds to its full forward reach of 29 feet. Primarily a pick-and-carry machine, the unit offers great visibility to the side and rear when a load is in the carry position. Good visibility is due in part to the low side-mounted engine and an efficient boom support structure design. 

Fuel fill is located behind the cab while the hydraulic fill is on other side of the machine, which helps to eliminate accidental contamination. Under the hood, the engine is mounted so all service points, including the starter, are in clear view. The battery is positioned at the front to easily jump start the machine.

The G6-42P uses the same JLG coupling unit that is standard on JLG, Lull, and SkyTrak machines, allowing operators with any of the three product lines to share attachments. This unit was shown with a 15-foot truss boom, but it is also available with a variety of standard, side-tilt, and swing carriages; pallet, lumber, and cubing forks; material and grapple buckets; a fork-mounted work platform; and lifting hook.
