Here is a quote from another user: "I started out this morning mowing tall wet grass that was about 1.5 weeks of growth mowing it down to 3 1/4". This mower had plenty of power for this and it cut it absolutely great with only a stringer here and there and with practically no clumping. The discharge was amazing, it sprayed those wet clippings out evenly like they were dry as a bone with minimal build up under the deck. This mower had the triangle fix on the left side only and did not have the lift kit installed." What does he mean by triangle fix?
