We purchased an HOP Blackman, Model Number 96144000900 and Serial Number 011218 a couple of years ago from Sams Club. Now the self-propelled feature on it does not work at all. We are unable to find the manual but are unable to. However, I called the Customer Service number on the back of the product and it referred me to Husqvarna Lawn Mover company. Can someone give us the locations of repair facilities in the area, connect me with the actual manufacturer, or can anyone help us find the manual to the unit? Please contact us by email at Jeffrey_V_Brown@hotmail.com.
