How to stop grass clumps with tractor mower?
I have a Craftsmen 42" ride-on tractor/mower that was a gift from my children because they thought the old man shouldn't push a mower around 3/4 acre. Now I have to use it! I'd rather not. The real irony is that I think I do more work now that I use it. I have the blade set at the highest setting, which is about 3-1/2"+, I have two mulching blades, I run the mower at high engine speed, but low travel speed --- much slower than walking. I mow the lawn about every 4-5 days to minimize the amount cut and generally in the hot sun of the afternoon when the grass is driest, but still the mower leaves clumps behind. Once I do the entire yard, I'll switch the mower to high travel speed and go over the entire yard just to remove the clumps. I'll even follow up with my push mower (Lawn-Boy --- which I love). The only thing I haven't tried is replacing the two year old blades --- although I did take them off and sharpen them by hand.
I also thought of perhaps putting two blades at 90 degrees to each other on EACH of the two rotors --- a total of 4 blades; I'm not sure the shank will hold them or if it's safe.
I noticed my neighbor with the same tractor discharging the grass rather than mulching --- I wonder if that's good for the lawn. My community doesn't collect grass clipping and I don't believe in them for mulch or compost, so collecting the cuttings is not a practical option.
