Backpack vs tow behind sprayer: what each one is for

A backpack sprayer is a tank worn on the back, with a pump, a wand and nozzles for spraying weed, pest and lawn treatments on lawns, gardens and shrubs. The pump is manual or battery powered. A tow-behind sprayer is a tank on wheels that is pulled behind a vehicle with a hitch, such as a tractor or riding mower, with a boom or wand for covering open ground. It suits large open areas where a vehicle can drive in straight passes, while a backpack suits beds, shrubs, fence lines and other tight areas where a vehicle cannot go.

No tow-behind sprayer appears in the listings for this guide, so the gear section below covers backpack sprayers only. The tow-behind side of this guide stays at the method level: what a tow-behind does, where it wins, and where it loses to a backpack.

Tool	Best for	Limit
Backpack sprayer	Tight areas, shrubs, fence lines, spot work	Tank carried on the back
Tow-behind sprayer	Open ground, large areas, straight passes	Needs a vehicle with a hitch

When a backpack wins

Reach for a backpack when the job is in tight areas or spot work: shrubs, garden beds, fence lines, orchards and other places where a vehicle cannot drive. A backpack needs no tractor, no hitch and no trailer, and it turns around plants and obstacles without a vehicle. The Field King pick is manual, while the VAXMAY and EARTHCRAFT picks are battery powered. A backpack also suits work where only part of a property needs spray, since the tank can be carried to the spot and back without driving a vehicle over the whole lawn.

When a tow-behind wins

Reach for a tow-behind when the job is open ground and the area is large enough for a vehicle to drive in straight passes. A tow-behind tank rides on wheels, so the operator does not carry the tank weight, and the spray covers ground in each pass without carrying the tank. The trade-off is access: a tow-behind needs a vehicle with a hitch, room to turn, and open ground. See our best tow behind sprayer roundup for tow-behind options.

Tank, pressure and nozzles: what to compare

Tank size affects how far one fill goes. The Field King pick states a 4 gallon tank, while the VAXMAY pick states a 2.6 gallon tank and the EARTHCRAFT pick states a 2.6 gallon tank in its title and bullets. Pressure affects how far spray reaches and how fine the droplets are. The Field King pick states a maximum pressure of 150 psi, the EARTHCRAFT pick states an adjustable pressure range from 0 to 100 PSI in its bullets, and the VAXMAY pick states 3 spray forces with no PSI figure stated. Nozzles decide the spray pattern. The Field King pick includes 6 nozzles, the EARTHCRAFT pick includes 6 nozzles, and the VAXMAY pick includes 5 mist nozzles.

The gear section: 3 backpack sprayers, ranked

The 3 picks below are all backpack sprayers, in rank order, from the Field King manual pick, through the VAXMAY battery pick, to the EARTHCRAFT battery pick. Each entry gives the tank, pressure, wand and nozzles stated, with warranty status where stated.

Safety

Wear eye protection and sturdy shoes when spraying, and keep children, pets and bystanders away from the work area. Follow the product label directions for the product at hand, and check wind before spraying so spray stays on the target area.

FAQ: mowing large lots

Can a backpack sprayer cover a large property?

A backpack sprayer suits tight areas and spot work, with tanks here of 4 gallons for the Field King pick and 2.6 gallons for the VAXMAY and EARTHCRAFT picks. For a large open lawn, a tow-behind sprayer suits straight passes better, while a backpack suits beds, shrubs and fence lines within that property.

Do I need a tow-behind sprayer for a large open lawn?

A tow-behind sprayer suits a large open lawn where a vehicle with a hitch can drive in straight passes. A backpack sprayer suits the same property for beds, shrubs and tight areas, so a property can use a backpack for edges and a tow-behind for open ground.

What pressure do these backpack sprayers state?

The Field King pick states a maximum pressure of 150 psi. The EARTHCRAFT pick states an adjustable pressure range from 0 to 100 PSI in its bullets. The VAXMAY pick states 3 spray forces with no PSI figure stated.

Which backpack sprayer states a warranty term?

The VAXMAY pick states a 1 Year warranty. The Field King pick and the EARTHCRAFT pick state no warranty term in their listings.

Can I use a backpack sprayer without a tractor?

Yes, a backpack sprayer is carried on the back and needs no tractor, hitch or trailer. A tow-behind sprayer needs a vehicle with a hitch, so it suits properties where a vehicle can already drive on the lawn.
