Walker D21d

A favorite tractor for municipal, institutional and government customers, in part because of the powerful Kubota, three-cylinder, liquid-cooled diesel engine.


One innovation 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 of the decks, implements and attachments built for the grass collection style machines.
