When does the stacker use the low gear?

The stacker utilizes low gear primarily when starting and driving backwards with a load due to the increased torque and control it provides in these scenarios. Low gear is advantageous in situations requiring greater power and stability, particularly when moving in reverse while carrying a load. This ensures that the stacker can effectively handle heavier weights without risking loss of control or stalling.

Driving backwards with a load increases the challenge of maintaining stability, and using low gear helps in minimizing the risk of tipping or accidents, as it allows the operator to manage the speed and power more precisely. Lower gears are designed to deliver a higher amount of torque at lower speeds, which is essential for safely maneuvering in situations where precision is crucial, especially when the direction of movement is reversed.

In contrast, other conditions like driving downhill, moving forward with a heavy load, or maneuvering in tight spaces may require different gear choices that are optimized for speed or traction rather than the low-range torque that is most effective when reversing with a load.
