Stihl Launches BT140, Its First Battery-Powered Auger
With battery tools becoming more widespread and more importantly, productive and reliable, it was only time before we saw augers or post-hole borers.
While the base machine is still mechanical, heavy metal groupies will notice the absence of a PTO shaft, while the gearbox used to drive the interlocking gears across the bed of the machine has also been removed.
Instead, the rotors are powered by five electric motors, one for every two rotors. Currently being tested behind a new hybrid tractor, a 700v DC connection provides the Alysium with 50-60kW of electrical power.
Still in the early stages of development prototype, development is centred around understanding what is possible with electrical propulsion, according to the company.
Challenges so far include safety, but already testers have found that the tractor uses up to 35% less fuel. Further benefits are the possibility of controlling rotor speed electrically, with variable speeds to offer real-time adaption to changing soils. It has not been confirmed when, or if, the concept will make it to production.
