John Deere has added three new models, the PD-72 inch, PD-84 inch, and PD-96 inch, to its referral attachment line from Level Best, a manufacturer of grading attachments. The new grade control-ready Level Best Dual Mast PD Series box blades are expected to improve productivity on John Deere skid steers and compact track loaders. 

Level Best box blades are available in Topcon ready 2D precision grading and 3D precision grading options. The 2D Level Best PD Series comes ready to produce precise 2D grading by working seamlessly with laser transmitters. The 2D system automatically adjusts the elevation by controlling the lift and tilt of the attachment to maintain vertical accuracy and smooth grading performance. The Level Best PD Series Grading Box System adjusts dozens of times per second to ensure a smooth grade with tight tolerances — ideal for precision grading.

Level Best designed the PD Series to take advantage of the push-pull directional work style of skid steer loaders for maximum production. The PD Series is made specifically for skid steer loaders and compact track loaders. The unique frame design gives operators control, efficiency, and smoothness, and minimizes the potential “bounce” effect that can occur in skid steer loaders due to the short wheelbase.

For jobs that demand 3D grading, Level Best grading boxes come ready to be used with Topcon GPS, robotic total stations, or sonic technology. The grading box comes installed with the cables needed to work with Topcon 3D GPS. This allows customers to use the Topcon GPS systems they currently use on other machines. The main components can be installed on the grading box for a plug-and-play solution.

The PD-72, PD-84, and PD-96 require machines equipped with half-inch quick-connect couplers and a 14-pin auxiliary electrical connector with live power. A rear counterweight is not required to use these models but will improve stability during use.
