- Offers two-speed travel options, with a maximum speed of about 7.1 mph (11 km/h) in high range.
- Available in standard flow or High Flow XPS configurations for enhanced attachment performance.
- Standard loader hydraulic flow rate is approximately 23 gallons per minute (86 liters per minute), with a max pressure around 3,335 psi (23,000 kPa).
- High Flow XPS offers up to 32 gallons per minute (121 liters per minute) and pressures up to 4,061 psi (28,000 kPa).
- Hydraulic power enables strong breakout force of around 7,285 pounds, facilitating heavy lifting and material handling.
- Industry-leading sealed and pressurized cab option ensures a clean, quiet operating environment with excellent visibility.
- High-back, heated, air-ride seats with adjustable joystick controls improve operator comfort and reduce fatigue.
- Optional advanced displays provide on-screen machine adjustments, multi-language support, and integrated rearview camera.
- Rated operating capacity at 35% tipping load is roughly 2,055 pounds (932 kg), with a tipping load near 5,870 pounds (2,663 kg).
- Compact dimensions include track lengths of roughly 64.2 inches in contact with the ground and overall length with bucket around 146 inches.
- Ground pressure is low, ranging between 4.4 to 4.9 psi, thanks to rubber tracks and optimized undercarriage design, improving traction and minimizing soil disturbance.
- Intelligent Leveling (ILEV) system offers electronic self-leveling and work tool return features enhancing productivity.
- Easy ground-level access to daily maintenance points reduces downtime.
- Efficient cooling and filtration systems contribute to durable operation.
- Hydraulic fluid capacity approximately 13.8 gallons.
- Radial Lift Design: Loader arm style offering superior reach at mid-lift positions.
- Tipping Load: The maximum load the loader can handle safely without tipping.
- Breakout Force: Force applied by the loader’s bucket to break into material.
- High Flow XPS: Optional hydraulic system delivering higher flow rates for heavy-duty attachments.
- Electronic Torque Management: System optimizing engine torque delivery for performance and fuel economy.
