There are 'limited' cat1 implements that can be used on cat0. For example the BEFCO 40" tiller can be ordered 540 cat1 or 2000 cat0. My 4' box is a limited cat1 or they called it the 'baby box'. My rake is a special limited 1/0 5' rake, boom is lowered for the lack of hight of the tractor. There is a 48" finish mower out there that can be converted to 2000 cat0....just a matter of cash.
