The 4930 was notable as the largest 30 Series Deere sprayer, offering a 1,200-gallon tank and 325-hp 9.0L engine in a stable, high-clearance package. Its capacity and 120-foot boom availability give well-kept machines a useful place in the used large-acre market.
Buying a used John Deere 4930
On a 4930, inspect the boom and center rack meticulously because the long boom and large tank place high loads on hinges, pivots, and suspension. Check product pump performance, plumbing, solenoids, wheel motors, tires, struts, and hydraulic systems for leaks and deferred repairs. Confirm engine hours, service records, cab electronics, rate controller, boom-height functions, and guidance hardware before assigning value.
