Go out in a Western New York alfalfa field with Big Tractor Power to see and hear big farm machines chopping haulage for dairy cow feed. YouTube Viewers will see a 230 hp John Deere 7230R tractor and 32ft Poettinger Nova Cat triple mower cut alfalfa. A 250 hp OXBO 4334 Self-Propelled merger combines 73ft of mowed alfalfa into one big windrow for the forage harvester. A 625 hp John Deere 7780 ProDrive Self Propelled forage harvester chops the alfalfa. Ten ton trucks carry the haylage back to the farm where a 375 hp John Deere 9320 4wd equipped with a Grouser blade pushes the feed in a bunk silo and a 235 hp Case International 9230 4wd with an Agromatic Big Foot Forage Packer seals in the feed.
