Key Features

600-Gal (2,300-L) Solution Tank
Up to 90 ft (27 m) Boom
27 mph (43 km/h) Transport Speed
173-hp (129-kW), 4.5 L (275 cu in.) Engine

Boom Strength That Delivers Consistent Coverage

High‑strength steel boom construction with a durable 3D design resists twisting and fore‑aft stress during starts, stops, and turns. Protected plumbing and breakaway ends reduce damage risk, helping maintain spray accuracy and uptime across challenging field conditions.

Compact Design That Maximizes Field Access

The R4023 pairs a compact footprint with up to a 27.4-m (90‑ft) boom, making it ideal for smaller, irregular, or confined fields. Fold‑in outer wings improve maneuverability on headlands and tight passes, helping operators spray more acres without sacrificing reach or efficiency.

Comfort and Control for Long Application Days

Features like an airbag suspension, ergonomic CommandARM™ controls, and improved sound suppression keep operators comfortable and confident. A smoother ride and intuitive controls reduce fatigue, so operators stay productive and precise during long spraying windows.
