It offers a lift capacity of 1,764 lbs (800 kg) at 24 inches behind the lift points, with a maximum capacity of 2,646 lbs (1,200 kg) at the ends.
Operator Environment and PTO
The machine comes standard with an enclosed cab including air-conditioning and an audio system. It features an independent, electro-hydraulically engaged rear PTO operating at 540 RPM. An optional mid-mount PTO is available for specific implement requirements.
Conclusion
