A400 John Deere Daytime

Swathing canola 10mph, tried 11-12 worked but fast, 10 cut well and comfortable, honeybee header was too excited about, but cut well, just had some vibrating issues and things falling off, I don't think longevity of it is there like the MacDon, so I still think MacDon has better machine and header but this A400 is 2nd, then case then that new massy, i tried a D450 = junk,
