I know everyone says how much faster a disc mower is compared to a sickle machine. I just wonder if it's worth the price in my setup of mowing 10 acre paddocks with rocks. I got crazy last year about the only thing I didn't replace was the old 720 JD MOCO. Tractors are JD4600, JD5520 and a JD6115, Krone tedder and rotary rake, New Holland 450 Roll belt baler and a Tanco wrapper for when the weather acts stupid. I just cut for myself and wonder if a disc mower would really be faster with the small fields and rock breaks? They sure are expensive and you can get sickle machines a dime a dozen around here. The JD dealer offered me like $1250 trade on a new moco !
