About 18 years ago I purchased a used Walker mower with the grass handler deck. It has a 16 horse Kohler engine and has served me very well. It seems that the suction does not lift the grass enough in some cases and leaves some grass uncut. Certain types of grass it will just kind of beat the ends off of it and leave just wispy ends.The impeller for the suction seem to be well worn and rounded. Is it possible that the impeller and housing need to be replaced. I do all my own maintenance on it and rebuilt all of the gear boxes several years ago. The dealer finds it hard to believe that it is still going so strong. As far as I know it is the original engine and has never been rebuilt. It uses no oil to speak of and is a great machine. I just think that my cutting is not what it used to be. I have fairly new blades on it and have sharpened them recently. Any ideas.
