9.5 mm 0.375" thick guarding protects the sides and rear of the fuel tank and hydraulic tank from damage and debris.
Additional perforated material increases air flow to the radiator and prevents large airborne materials from entering the engine compartment.
These sheet metal guards are welded to the perimeter of the engine compartment doors, providing an overlapping barrier against material intrusion into the engine compartment.
Front striker bars are designed to prevent debris from riding up on the tracks and damaging the chassis or cab glass. The bolt-on design allows for easy servicing.
The 1682 kg 3,708 lb for the PX model and the 2000 kg 4,409 lb for the EX model counterweight optimizes machine balance for landfill applications.
The hydraulic oil cooler is relocated to the rear to increase cooling efficiency. It features a flexible core heat exchanger for easier cleaning and maintenance.
The AC condenser is mounted to the roof to protect it from debris and to increase cooling efficiency.
The thermal guard covers the exhaust manifold, hot side of the turbocharger, KDPF, and SCR system, reducing the potential for combustible debris to come in contact with hot surfaces.
A protective screen is added to the standard centrifugal engine air pre-cleaner to remove large particles from the air before they reach the filter elements.
The electric winch located on the inside of the main frame lowers and raises the underguard, providing easy access to the engine compartment for cleaning accumulated trash.
The two-piece radiator guard doors allow access to the standard wide-core radiator for cleaning. Adjustable fan reversing interval and duration allow the operator to concentrate on productivity, while helping to keep the radiator clean.
The two hood-mounted lights are replaced with four LED work lights mounted high on the blade lift cylinders, casting light over the trash rack.
The see-through vertical bars of the trash rack are designed to ensure good operator visibility. The trash rack and blade are both painted matte black to reduce glare.
The optional, cab air-filtration system provides pre-cleaned, filtered air to the HVAC system. The cab is pressurized to minimize odors and dust.

Palm Command Control System (PCCS) lever controls for all directional movements. Pushing the PCCS lever forward results in forward machine travel, while pulling it rearward reverses the machine. Simply tilt the PCCS lever to left to make a left turn. Tilt it to the right for a right turn.
Hydrostatic Steering System (HSS) is powered by steering planetary units and an independent hydraulic pump and motor. Counterrotation turns are also available. Wet, multiple-disc, pedal-controlled service brakes are spring-actuated and hydraulically released. Gear shift lock lever also applies parking brake.
