Fender Switch
A button placed on the tractor's rear fender that allows the rear links to be raised and lowered without climbing into the cab. The operator can stand beside the implement and align the lower links with the pins; for this reason the movement is deliberately kept slow. It turns attaching an implement from a two-person job into a one-person job. These switches are included in the ELF-812 set.
The fender switch is a well-established solution that tractor manufacturers have used for a long time; the switches supplied in AXI's ELF-812 set bring the same function to a classic hydraulically controlled tractor. The working principle is simple: the button sends a raise or lower command to the control module, and the module drives the actuator.
- Why slow: the operator is right next to the moving implement; fast movement creates a crushing risk. Slow movement both makes alignment easier and is safer.
- Where it is fitted: at a point that is easy to reach but will not be struck by branches, the implement or stones; the cable is routed under the fender so that it will not chafe.
- Safety habit: when using the switch, never go under the implement or between the lower links and the implement.
The joystick inside the cab and the fender switch are connected to the same control module; both trigger the same movement. For an operator working alone in the field, the real gain is the elimination of climbing in and out of the cab repeatedly to catch the implement.
