Donbar Support Bar for Zero-Turn Lawn Mowers. The Donbar was developed to assist in the mounting and dismounting of a zero-turn lawn mower. The Donbar provides stability and balance for people facing physical and/or strength challenges by offering an extra point of contact when climbing on and off a mower or moving from a sitting to a standing position and is adjustable to five different angles! The device mounts on the foot plate of the zero-turn lawn mower (often using the plate's existing holes) and is secured by lock-nuts to resist loosening caused by vibration and torque. The Donbar is compatible with a variety of zero-turn lawn mowers, including John Deere, Toro, Exmark and most others.

Installation Instructions:

The DONBAR must be anchored securely to Zero-Turn mower foot plate. The DONBAR is mounted with four bolts passing through the DONBAR mounting bracket and then passing through four existing holes in the Zero-Turn mower foot plate. The DONBAR is secured with a locking nut on each of the four bolts. 

1. Each brand of Zero-Turn lawn mower has a unique style of floor board that may or may not have an array of holes existing. Check and see if any or all of these holes may match with the DONBAR mounting bracket holes. If so utilize the holes that do match and drill the remaining holes to complete the preparation for mounting the DONBAR to the floor plate.
2. Place a 5/16th flat washer on each of the four 5/16th bolts. 
3. Place the four 5/16th bolts with the flat washers through the mounting holes in the DONBAR base plate. 
4. Lower the DONBAR base plate onto the Zero-Turn foot plate with the four 5/16th bolt passing through matching holes in the foot plate.
