Hi: First, let me say I am an older woman, who has no man to help me out with stupid questions regarding yard equipment. I recently had to replace my lawnmower, which was stolen from my garage when we first moved to a new place. I bought another Honda, with the same model number as my other one, but it is not exactly like my other one. Mine had a dial on the top of the mower which would let you change from mulching to bag. This one I have now does not have the dial. When I mow without the bag, it gets stopped up where the grass would usually go into the bag. I have to stop every once in awhile and get the grass out of the discharge hole. I don't think my other mower had one of those mulch plugs this one has. I finally realized the plug needs to be removed when mowing without the bag but it still gets plugged up. Is it because the grass is too high and the opening won't accomodate it or it is too wet? Any help would be greatly appreciated.
