What contributes to the elevation of the center of gravity on a TLB with a backhoe attachment?

The elevation of the center of gravity on a tractor-loader-backhoe (TLB) with a backhoe attachment is significantly influenced by its location high above the ground and far behind the wheelbase. When the backhoe attachment is in operation, it extends out from the rear of the machine, creating a larger moment arm that raises the center of gravity. This elevated position can lead to stability concerns, especially when the machine is turning or navigating uneven terrain.

Additionally, as the backhoe is raised or extended, the weight shifts, further contributing to the height of the center of gravity. Operators need to be aware of this dynamic to ensure safe operation, particularly when loading, digging, or transitioning between different tasks. The stability can be compromised if the center of gravity moves too high or too far from the base, leading to potential tipping hazards.

In contrast, factors such as the weight distribution of the front wheels, the design of the backhoe itself, and the balance of the machine's axle have their own roles, but they do not have as direct a correlation with the elevation of the center of gravity as the position of the attachment relative to the frame of the TLB does.
