On 300 acres of alfalfa I have 5 times that equipment. 5 newer 5070 hayliner balers, 4 tractors , a self propelled rotary cutter and a back up cutter , and help! Farming isn't as easy as your calculations. You only get as many cuttings as the weather allows, ALL equipment breaks even brand new equipment. Be ready for repair bills. I have never used an accumulator or grappler. We run NH balewagons.
