The Chapin 98004 40-Gallon 3-Point Hitch Sprayer is engineered for landowners, homesteaders, and agricultural operators who demand dependable, large-scale liquid coverage. Designed to hitch directly onto a category-compatible tractor 3-point system, this comprehensive spraying setup allows you to easily distribute liquid fertilizers, weed control herbicides, and pest treatments across acreage, orchards, pastures, and commercial landscapes.
Performance is driven by a rugged 5 GPM 12-volt diaphragm pump that connects to your vehicle battery using an alligator-clip wiring harness and an inline on/off toggle switch. Unlike standard pumps, Chapin's diaphragm mechanism is designed to safely run dry without burning out seals or shafts. The 10-foot wide boom utilizes seven evenly spaced nozzles for consistent blanket coverage, while spring-loaded breakaway joints safeguard the boom from structural damage if you encounter fence posts or trees.
In addition to broad broadcast spraying, the system includes a 20-inch poly wand connected to a 180-inch (15-foot) reinforced hose. This setup lets you transition instantly to spot spraying for fence lines, ditches, and garden beds. Maintenance headaches are minimized thanks to a triple-filtration system located at the tank basket, inline pump filter, and wand shut-off handle, keeping unwanted grit from clogging the spray tips.
Potential buyers should consider that this is a substantial piece of farm equipment. Weighing over 200 pounds in its complete configuration, installation onto the tractor hitch is significantly easier as a two-person job. You will also need sufficient clearance and barn space to store the extended boom frame when it is dismounted from the tractor.
Ultimately, the Chapin 98004 stands out as a commercial-grade spraying workhorse that saves hours of field labor. With its robust run-dry pump, breakaway boom system, and proven build quality backed by a 5-year limited warranty, it is an outstanding asset for serious acreage maintenance.
