These deep flat-top cutting decks offer an enhanced air-flow of between 20 – 25% compared with the previous design. The deep 11.4cm deck shell is manufactured from a single piece of pressed steel & has eliminated edges or corners where grass build up can reduce the mowing performance. The Accel Deep™ cutter decks are available in 42, 48 & 54 inch cutting widths. The Accel 48A has a 48 inch / 122 cm cutting width & features adjustable anti-scalp wheels to help the deck ‘float’ over the lawn surface. Manufactured from 10 gauge steel this deck is 23% heavier than the previous 48” Edge deck. The Accel decks can only be fitted to compatible 2016 onward John Deere garden tractors & cannot be retro fitted to any pre-2016 models.
