Buying Guide
What size 40-gallon sprayer is right for me?
Consider your acreage, spraying cadence, and transport method. ATVs and UTVs favor compact 40-gallon models for maneuverability, while trailer-mounted units can carry larger tanks for extended jobs.
Which boom width and nozzle count should I choose?
Wider booms reduce the number of passes but may drift in windy conditions. A 7-nozzle or 10-foot boom provides broad coverage, while a 2-nozzle or 10-foot boom is adequate for precise spot treatment. Independent nozzle controls help target specific areas.
How important is pump flow and pressure?
A higher GPM (gallons per minute) improves speed and distribution, especially at higher vehicle speeds. Look for pumps with 2.2–4.0 GPM and 45–70 PSI range for versatile applications with herbicides, fertilizers, and pesticides.
What about tank material and durability?
UV resistance, chemical compatibility, and tank thickness affect longevity. Poly tanks are common, durable, and resistant to most agricultural chemicals. A translucent tank helps monitor liquid levels quickly.
Ease of mounting and maintenance
Choose models with easy mounting options (ATV/UTV hitch, 3-point hitch, or trailer). Quick-connect pumps and dry-run capability reduce maintenance downtime and extend pump life.
Maintenance tips for long life
- Rinse the tank after use to prevent chemical buildup.
- Inspect hoses and seals for wear and replace as needed.
- Store off-season in a cool, dry place to prevent resin cracking.
Common buyer decisions
- Best for: ATV/UTV users needing quick setup and balanced spray coverage.
- Better for: Larger properties requiring higher flow and more extensive spray patterns.
- Choose this if: You need a compact footprint with reliable performance and solid support.
