FAQs

What is a 300 gallon field sprayer?
A 300 gallon field sprayer is an agricultural pull-type or tractor-mounted sprayer equipped with a 300 gal capacity tank, designed for efficient application of fertilizers, herbicides, and pesticides over large fields.
How many acres will a 300 gallon sprayer cover?
Coverage varies by application rate, but at a common 20 gal/acre rate, a 300 gal sprayer will cover up to 15 acres per fill.
Which capacity farm sprayer should I choose?
It depends on your farm size and how often you want to refill. For under 10 acres, a 200 to 300 gal sprayer offers easy maneuvering. For 10 to 30 acres, a 300 to 500 gal model balances capacity and handling. Over 30 acres, step up to an 800 gal or larger unit to spend less time refilling.
Can I put both chemicals and fertilizer in my pasture sprayer?
Yes, your pasture sprayer can handle liquid fertilizers, herbicides and pesticides. Just check that the products are compatible, rinse the tank and lines between mixes, and follow the manufacturer’s nozzle and pressure guidelines.
How do I decide between a pull type sprayer and a skid mount sprayer?
Pull type sprayers hook to any Category 1 hitch and are ideal for fields and pastures. Skid mount sprayers install on a flatbed, truck, or ATV skid plate for quick swaps between vehicles. Choose pull type for towing behind a tractor, skid mount if you need to move your sprayer among multiple platforms.
What maintenance do I need after using chemicals in my sprayer?
After spraying, flush the tank and lines with clean water, run a tank-cleaning solution, then rinse again. Inspect and clean nozzles, check seals and hoses for wear, and store your sprayer under cover to protect fittings.
