Model D

The Model D is designed with the same footprint as the Model T, making it compact and capable of mowing both small and large properties while also boasting a transverse mounted, 3 cylinder diesel engine and liquid cooling. A self-cleaning, reversing radiator fan keeps the Model D cool and efficient even in the toughest conditions. Weighing in just under 1,200 lbs, the Model D is one of the lightest diesel-equipped commercial mowers on the market.

This protects the turf from matting and rutting, while allowing the Model D to remain well-balanced and agile. Compatible with nearly all Walker mowing decks and add-ons, the Model D is a favorite with municipalities and institutional customers. A non-collection version without the GHS blower and Grass Catcher is also available. The non-collection model features a utility dump-bed in place of the grass catcher.
