Complete Disc Mower Blade Kit for New Idea, Massey Ferguson, Agco, Hesston and More SKU: 5408BK

Measure blade bolt hole before ordering.  5200/5400 New Idea older models often use a smaller .720" to .728" (approx. 18.5mm) hole. Newer models typically use a larger .890" hole

When disc mower blades get dull or chipped, they stop cutting cleanly and start pushing crop material around instead of slicing through it. This complete 12-blade kit restores the sharp, precise cutting action your New Idea 5408 needs for quality forage harvest.
