Walker Mowers


A favorite tractor for municipal, institutional and government customers is the MD. This is in part because of the powerful Kubota, three-cylinder, liquid-cooled diesel engine. One innovation highlight of the D21d is a self-reversing fan to keep radiator clean. The D-series shares the same basic design as the T-series and is capable of using most all of the decks, implements and attachments built for the grass collection style machines.
