Looking to buy a used mower. I have all the tools and mechanical capabilities to fix any and everything that may go wrong on a mower. I am looking at a 36" Ransomes. Everything seems to be in working order except the blades run constantly. You release the handle and the blades do NOT stop. Before I buy this mower I would like some advice on what this is so I can price out the part. I am guessing there is some sort of linkage that activates a pulley to turn the blades and that is the issue. I never owned a Ransomes So I am not sure. Thanks.
