The listing names herbicide, fertilizer and pesticide, and says it fits most ATVs and utility racks.

The listing does not say if a battery or charger is included, or give a pressure or runtime, so check the product page.

Skip it if you want a stated runtime; the PetraTools HD4000 Backpack Sprayer lists 6 to 8 hours.

10. CRAFTSMAN 20V Lithium-ion Battery Powered 4 Gallon Backpack Sprayer (Best 20V sprayer with battery included)

Skip it if you want adjustable PSI; the PetraTools HD4000 Backpack Sprayer lists 40 to 90 PSI.

Match Tank Size and Flow to Your Acreage

A small tank means constant refills. A 25 gallon rig like the FIMCO 25 Gal ATV Sprayer covers more per trip than a 15 gallon one like the CHAPIN 97154 15 Gal Sprayer, and a 45 gallon unit like the FIMCO 45 Gal UTV Sprayer covers more again. A 4 gallon backpack like the PetraTools HD4000 Backpack Sprayer suits small plots and rows.

Flow matters too. Pumps range from 1.0 GPM on the CHAPIN 97400E 25 Gal Spot Sprayer to 4.5 GPM on the FIMCO 45 Gal UTV Sprayer. A higher flow lets a boom put out liquid across a wide pass. A low flow pump is fine for spot work with a wand.

Calibrate Before You Spray the Whole Field

The most expensive mistake is spraying without measuring. Each product label gives a rate per acre or per 1,000 sq ft. Fill the tank with plain water, spray a measured test area and see how much you used. That tells you how much product to mix.

Then watch the weather. Do not spray in wind that can carry drift, and keep nozzles clean. Filters like the three stage ones on the CHAPIN 97400E 25 Gal Spot Sprayer help prevent clogs. Rinse the tank and lines after each use, and keep sprayers used for herbicide separate from those used on food crops when you can.

How to Pick a Power Sprayer for Farm Work

Power and warranty

12 volt vehicle pumps need a battery. The CHAPIN 97400E 25 Gal Spot Sprayer lists a 1 year warranty, and the CRAFTSMAN 20V 4 Gal Backpack Sprayer includes a battery and charger.

Frequently Asked Questions

What is the best power sprayer for agriculture?

For larger acreage, the FIMCO 45 Gal UTV Sprayer is the best pick here, with a 45 gallon tank and a 36 ft boom. For small plots and rows, the PetraTools HD4000 Backpack Sprayer is a backpack option.

ATV sprayer vs backpack sprayer: which is better?

An ATV or UTV sprayer like the FIMCO 25 Gal ATV Sprayer covers much more ground per fill. A backpack like the PetraTools HD4000 Backpack Sprayer reaches tight rows and uneven ground. Choose by acreage and terrain.

Can I use one sprayer for herbicide and fertilizer?

You can, but rinse well between products, and keep a separate sprayer for herbicide if you can. Check the label of each product for tank mix and cleanup directions.

How do I stop nozzles from clogging?

Use filters and clean water. Units like the CHAPIN 97400E 25 Gal Spot Sprayer and CHAPIN 97154 15 Gal Sprayer list in-tank and shut-off filters. Rinse after each use.

Do I need a boom?

A boom saves time on open ground. The FIMCO 25 Gal ATV Sprayer lists a 36 ft broadcast boom. A boomless setup like the Ag Spray 25 Gal Boomless 4.0 GPM gives 30 ft with no boom to snag on fences.
