All dimensions, weights, and performance values based on SAE J732c and J742b standards.
Static tipping load and operating weight shown include lubricant, coolant, full fuel tank, ROPS canopy, air conditioner, bucket and operator. Machine stability and
operating weight are affected by counterweight, or ballast, tire size, and other attachments.
Use either counterweight or ballast, not both. Apply the following weight changes to operating weight and static tipping load.
