All-Wheel Drive System All-wheel drive improves tractive performance in poor underfoot conditions. The Variable Horsepower feature comes standard on the 143H. With three operating modes � automatic, manual, and off � the operator can match performance to any application.

		Constant Net Horsepower This exclusive system increases horsepower in all gears when all-wheel drive is engaged. The additional horsepower compensates for power redirected to hydraulic pumps and front motors. The system delivers a smooth constant net horsepower in all gears, delivering more power to the ground.
