What is the added value of the swivel castors on the Jo Beau V460 scarifier?

JO BEAU opted for swivel castors at the back of the device. This equals more ergonomics and ease of use. The castors ensure that the machine operator does not have to lift or push the device down at the end of every lane on the lawn. Even around trees and curved lawn edges, the device can neatly follow the lane, without scarifying in angles.
