What the 4730 is used for
The 4730 is built for efficient coverage of medium to large row-crop acreages, with an 800-gallon tank and booms that commonly span 80 to 100 feet. Its high-clearance chassis, four-wheel-drive hydrostatic system, and suspended wheel layout support work across uneven fields.
Used buyers value the 4730 for its durable 30 Series platform, workable size, and strong parts familiarity. It remains especially attractive to owners who want a capable self-propelled sprayer without moving to the larger 1,000-gallon chassis.
Why the John Deere 4730 stands out
The 4730 became a highly visible 800-gallon Deere sprayer because it paired 245 hp with a stable independent-strut chassis and a well-supported cab and control system. Its size, common 90- and 100-foot boom configurations, and established resale following make it one of the benchmark used Deere sprayers.
Buying a used John Deere 4730
Inspect all boom sections, main-frame welds, pivot pins, breakaways, and plumbing for fatigue, seepage, or poor repairs. Test the hydraulic product pump, section valves, wheel motors, suspension struts, and tread adjustment under operating conditions. Review engine service records and confirm the SprayStar display, rate controller, boom-height equipment, and guidance-related electronics function correctly.
