on our 60" Lazer we bought a mulch kit and are running exmark mulching blades on them it work great in the early spring casue the grass wasnt growing that much boss thought it was the cat azz cause it didnt leave any clumps and cut great. Now I told the boss that it will only work when the grass isnt growng that much and now its in its prime growing season and is sometimes 6" + higher and the mower just cant cut it CLEAN the first time plus it clumps i end up haveing to double cut everything. is it common for mulching kits to cause the mower to not cut clean i mean it leaves lots of scragglys and turf turds on the first cut???? I just dont thinks its physically possible to mow with mulch kits and long grass??? I robs the enging of hp and have to spend more time on the property cause of dbble cutting. Im lobbying for a quikshut or something like that to save on blowing so i can pull the baffles off and discharge.
