Features

Comfortable Cab

Industry leading sealed and pressurized cab option provides a cleaner and quieter operating environment with excellent work tool visibility. Available high-back, heated, air ride seat with seat mounted adjustable joystick controls makes the D Series the industry leader in operator comfort.

Outstanding Power

High performance power train provides maximum performance and production capability through the Electronic Torque Management system, optional two speed travel and an industry exclusive electronic hand/foot throttle with decel pedal capability. Electronically controlled Cat C3.3B engine provides high horsepower and torque while meeting U.S. EPA Tier 4 Final (EU Stage IIIB) emission standards. High Flow hydraulic system is available for applications that demand maximum hydraulic work tool performance.

Versatility to Tackle Any Job

Cat “Intelligent Leveling” system (ILEV) provides industry leading technology, integration and optional features such as dual direction self level, work tool return to dig and work tool positioner. Standard fully independent torsion axle suspension combined with the optional Speed Sensitive Ride Control system improves operation on rough terrain, enabling better load retention, increased productivity and greater operator comfort. Broad range of performance matched Cat Work Tools makes the Cat Multi Terrain Loader the most versatile machine on the job site.

Advanced Display

Maximize machine capability and control with optional Advanced Display providing on-screen adjustments for implement response, hystat response and creep control. The display also features multi-language functionality with customizable layouts, security system and rearview camera.

Easy Service

Ground level access to all daily service and routine maintenance points helps reduce machine downtime for greater productivity.
