Buying Guide: Key Considerations for Zero Turn Mower Sprayers
Choosing the right sprayer depends on your yard size, terrain, and spraying tasks. Consider tank capacity, pump flow, spray width, and ruggedness of the cart and boom system.
What size tank do I need?
For small yards, 15–21 gallons may be sufficient. Medium yards benefit from 25 gallons, while larger properties can justify 31 gallons or more. Larger tanks reduce refills but add weight and towing demand.
How important is pump flow and pressure?
Higher GPM and PSI translate to faster coverage, especially on broad lawn areas. For professional or high-output uses, a continuous-duty pump like those in NorthStar NSQ models offers steady performance under long service.
Is a spray boom or a spray wand better?
Booms provide wider, even coverage and are efficient for open areas. Wand-based kits offer precise spot spraying and can be advantageous for edge work and targeted weed control.
What about durability and maintenance?
Look for UV-resistant tanks, powder-coated frames, and corrosion-resistant valves. Breakaway booms protect against impact damage in uneven terrain. Regularly check seals and diaphragms to extend pump life.
How do I match a sprayer to my mower?
Choose a trailer sprayer with a compatible hitch and towing capacity for your mower. Consider storage space, road regulations, and ease of mounting and dismounting on your property.
Operational tips for best results
- Calibrate your nozzle pattern and flow before large applications to minimize waste and run-off.
- Keep a consistent walking or mowing pace to ensure uniform coverage.
- Inspect hoses and fittings for leaks after each use to prevent chemical exposure and damage.
Frequently Asked Questions
- What spray width should I expect from a 7-foot booms? – Typical full-width coverage is around 70 inches, with adjustable settings to match terrain.
- Can these sprayers handle Roundup or other herbicides? – Most models are designed for agricultural herbicides, but always verify compatibility with the manufacturer’s guidelines for specific chemicals.
- Do I need a special hitch for my zero turn mower? – A standard trailer hitch compatible with your mower’s towing setup is usually sufficient, but confirm weight ratings and compatibility.
- How often should I replace pump diaphragms? – Diaphragms are wear items; replace when you notice reduced flow or performance. Regular maintenance extends life.
