For such a small part, the spray gun has a big impact on your business. Learning what to look for in a spray gun can help ensure that you’re investing in a durable, quality piece of equipment for your rig.

Uses: Spray guns, like the industry leading Lesco spray gun, are multifunctional and able to be used across an array of lawn care and agricultural spraying applications including herbicides and pesticides for turf, tree and pest control.

Cost: The standard price range for a chemical spray gun will run you anywhere from $50-$175, but with proper maintenance, this investment will pay itself off. Be sure to double-check your equipment manual for longevity of your spray gun.

Features:

  • Materials: Spray guns are commonly constructed from materials like nylon, stainless steal or brass, which stands up well to deterioration.
  • Nozzles: Popular chemical spray guns offer different options for nozzle tips that are interchangeable through a simple threaded connection. Nozzles are typically color coded to distinguish the size and volume of liquid the tip delivers, allowing you to select the best nozzle for your application.
    • Droplet Size: Pay attention to the droplet size offered by your nozzle. A larger droplet will reduce drift for a more accurate application.
    • Nozzle Pressure:Maximum operating nozzle pressure will vary depending on your gun.  Exceeding maximum pressure may cause leaks. Be sure to choose the right nozzle based on your operating pressure needs.
  • Spray Patterns:Most lawn spray guns offer a showerhead spray pattern, which spray in a 45-degree cone. There are other options available, including adjustable guns that offer a variety of patterns from fine mists to long, precise streams.
  • Trigger Locks:A trigger lock is a popular feature on most spray guns and is a must for many jobs. This allows for continuous spraying while giving your finger a break.

 

Maintenance: Like all parts on your rig, spray guns require maintenance to continue working effectively. Following these annual preventative maintenance tips will help you save money and increase the lifespan of your spray gun and nozzle:

  • Soak the nozzle in a mineral oil to help keep it lubricated. Do this in your off-season as a proactive measure to prevent the plastic from dehydrating.
  • Fill the trigger assembly with anti-freeze to winterize your spray gun if it’s exposed to freezing temperatures during storage.
  • Monitor the wear on your hose barb, replacing it when you notice corrosion. The hose barb can weaken over time as a result of the oscillating motion of spraying.
  • Clean, grease and look over your spray gun for signs of deterioration and replace O-rings, triggers and internal assembly as necessary. Repair kits are available for this purpose.
