I'm in Michigan and have just finished getting all the mowers ready for winter, but I couldn't check the rpm limits as the piece of equipment I've been using for the past 12 years jumped off the shelf and broke into alot of pieces. I don't want to talk about how that happened!! So, I need to purchase a new one, what brand? where to buy? I am not a repair tech, just like to maintain my own equipment. Any suggestions appreciated.
