Hi folks..gravelman from So NH i have a Kodiak 60" heavy duty rotary cutter... i am unable to find replacement blades, there are two. This seems very strange to me not finding anyone with blades to fit. I have had it two years and this is my first time replacing blades. Any suggestions would be greatly appreciated. They are 24 1/2 " long, 4" wide and bolt hole of 1 1/8th i guess that is pretty much standard???
