went to my local guy ( not exmark dealer ) to pick up some extra blades for my exmarks, turns out the only one he could get that would fit my arbor, and size is a bahia blade? anyone heard of it? i onle heard mention of it before, i beleive it's for thick greass called bahia? im in chicago we got fescues just wondering if it would work well? maybe better since it's design for heavy cutting?
