An out-front machine has many advantages over rear mounted, including operator comfort and visibility and it's maneuverability in confined areas, around road signs, trees and other obstacles. Not only will the Wessex ProLine TGX 150 cope with longer grass on roadside verges, but it will also leave a premium result on sports turf at high speed with no grass swathing, as with a rotary machine.
