Could badly do with upgrading the sprayer. I never use it but the old man does it all and the amount were doing gets bigger every year. What would 4-5k buy? Anything half decent? Something around 1000 litres folding booms but doesn't need to be wide. World and all of 3-4 acre fields around here you spend more time folding booms than you do spraying. Hardi or berthoud are the best are they?.
