What the 4720 is used for
The 4720 is designed for long field passes in row-crop work where 800 gallons of onboard capacity and an 80- or 90-foot boom provide practical daily coverage. Its 60-inch clearance allows it to travel over taller crops while the adjustable chassis helps match common row spacings.
Today, owners often regard it as an accessible used self-propelled sprayer for farms that do not require a 1,000-gallon machine. It remains useful where service support and a careful pre-purchase inspection outweigh the appeal of newer precision features.
Why the John Deere 4720 stands out
The 4720 refined Deere's early 4700-series formula with more power while retaining the high-clearance chassis, hydrostatic four-wheel drive, and familiar 800-gallon capacity. Its broad dealer footprint and conventional 6.8L Deere engine support its reputation as a workable older large-acre machine.
Buying a used John Deere 4720
Closely examine boom folds, hinge pins, breakaway structures, boom plumbing, and valve response. Check the centrifugal product pump, hydraulic wheel motors, suspension struts, tread-adjust system, tire wear, and steering for leaks or excessive play. Run every cab control, display, and rate-control function and compare recorded engine hours and maintenance history with the machine's overall condition.
