I have had this mower since new and has served me well, I cut about 2 acres of grass all summer and pick up leaves in fall with a jarco wagon and it works great without a power flow. My concern now is a noise, like a bearing or? I have taken the mower deck off, it does it when it idles but does not vary with engine speed. When I push on the brake peddle and lock it with the brake lock it quits and as soon as I release it and go, the noise is there. I do not think it is the engine bearing as it is a steady speed. If it were in the engine it would vary with the engine speed. Would like to get it fixed before spring and would like to do myself and not take to dealer. I have taken the seat, and frame cover off and I cannot pinpoint the noise. Anyone have any ideas? Thanks for the help
