What the 4930 is used for
The 4930 is intended for large farms and commercial-scale field work where a 1,200-gallon tank reduces refill interruptions and 90- to 120-foot booms cover wide passes. Its high clearance, power reserve, and heavy chassis suit long workdays over extensive acreage.
Owners continue to value it as a substantial pre-R-Series Deere platform with a large tank and familiar operating layout. It is best matched to operations that can support the machine's size, transport needs, and detailed maintenance requirements.
Why the John Deere 4930 stands out
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, tyres, 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.
