Designed as an assistive aid for persons who have balance/stability issues, this Zero-Turn Mower Support Arm – called the Donbar – provides a needed extra point of contact when the operator climbs on or off their mower, and when shifting from a sitting to a standing position. Manufactured by DB Mower Industries in Blaine, Minnesota, the device mounts on the foot plate of a zero-turn mower using the plate’s provided mounting holes and the mounting bolts are secured by lock-nuts to resist loosening caused by vibration and torque. Four models available to fit popular zero-turn mowers from John Deere, Toro, Grasshopper and more. $94.95 plus shipping. More info: http://dbmower.com.
