The MAV is amazing, its easily spreading the straw 36ft., its also chopping it to bits and doing a good job on the chaff. To get the chaff into the chopper it has an extension bolted onto the sieve with a rubber flap, this allows the chaff to move off the sieve and into the chopper, its a very simple design. The MAV will still allow you to spread chaff while dropping straw, I'm glad we went ahead and stuck it on, it should save a pass with the harrows. The winter wheat was only testing 17, but the straw was very tough. As for quality, well it remains a two after all the rain, but this last one sure bleached it out, rained again today...hopefully tomorrow we can get rolling, supposed to be sunny, I'll believe it when I see it!
