Ok guys this is my first post so be gentle. I have a Scag 19/48 tiger cub with a kaw engine I got it about year and a half ago an have about 600 hrs on it. Lately i have noticed the mower bogges down on hills and in thicker grass. Even more with the catcher on but that is to be expected. I asked the local dealer about it and did all the maintence stuff they recommended but still same old thing. ANy suggestions or anyone have similar problems. I have had the hydro fluid changed at the beginnin of this yr so that has been done. Any help will be appreciated.
