Disconnect and Transport Electric Fence Components

What happens here

The farmer drives his Honda Foreman 4x4 ES ATV to the existing electric fence setup. He disconnects the electric fence controller and the associated car battery from the current fence line. He then places these components onto the ATV's front and rear racks for transport to the new grazing area. The farmer highlights that he repurposes old automotive batteries, which are no longer strong enough to start a vehicle, to power the electric fence controllers. These batteries can still provide sufficient power for the fence for 1-2 years.
