The STIHL FBD-KM Bed Redefiner is a durable and efficient KombiSystem attachment for maintaining existing mulch and flower beds. Features like a clog-minimizing deflector design, a cost-effective cutting geometry blade and an adjustable depth wheel help you get the job done up to seven times faster than you could manually. In addition, a solid drive shaft and a protective gearbox plate make this bed redefiner a durable piece of equipment that’s an affordable alternative to a dedicated bed redefiner. The STIHL FBD-KM is recommended for use with the KM 131 R, but can be used with the KM 91 R and KM 111 R. NOTE: STIHL KombiMotors and STIHL KombiSystem attachments are sold separately.
