Third Gear Selected Warning System

The Third Gear Warning System monitors and alerts the operator if they’ve selected forward or reverse in third gear, preventing damage to the track and drive train.
SKU: HMLI004
$409.00

The Third Gear Warning System monitors and alerts the operator if they’ve selected forward or reverse in third gear, preventing damage to the track and drive train.

Using the third gear on your dozer can reduce the lifetime of the tracks by 50%. This can result in tens of thousands of dollars spent on replacements, depending on the model of your dozer.

Avoiding any unnecessary machine down time. When third gear is selected, the systems outputs activate a critical alarm/LED warning, which will appear on the dash along with an external flashing beacon, if connected.

The third gear has to be selected for a short period of time to confirm the warning system to occur.

The control device will alert the operator after the machine has selected third gear for a period of three seconds.

Prevent heavy vehicle damage with third gear alerts 

This delay prevents unnecessary alerts in the event of gear selection errors. This device is designed to prevent any damage and prolong the life expectancy of the undercarriage of the vehicle.

The warning system can be paired with other Hummingbird devices, such as the Audio Alert System or Combination LED and buzzer to further improve longevity of your fleet.
