In this guide, we’ll explore the most popular types of weed sprayers in Australia, from battery-powered sprayers to trailer-mounted units, boom kits, ATV-compatible sprayers, and everything in between. We’ll also help you decide which option suits your property size, weed control goals, and equipment setup.
What is a Weed Sprayer?
A weed sprayer is a device used to apply herbicides or other liquid treatments to control weeds over a specific area. Depending on the model, weed sprayers can range from handheld units for spot treatments to trailer-mounted weed sprayers designed for large-scale spraying over several hectares.
Types of Weed Sprayers
1. Weed Sprayer Trailer
A weed sprayer trailer is ideal for medium to large properties. These units come with a tank mounted on a trailer that can be towed behind a quad bike, tractor, or ride-on mower. They often include a boom sprayer or a handheld wand for precise application.
Great for: Paddocks, farms, acreages, and large lawns.
Popular sizes: 100L, 200L, and even larger.
Key feature: Trailer-mounted weed sprayers are perfect for covering large areas efficiently.
2. Battery-Powered Weed Sprayer
A battery-powered weed sprayer offers the convenience of cordless operation without manual pumping. These sprayers are lightweight, quiet, and ideal for residential and small-scale agricultural use.
Great for: Home gardens, driveways, small plots.
Power source: Rechargeable 12V or 18V batteries.
Look for: Consistent pressure output and long battery life.
3. 12V Weed Sprayers
12V weed sprayers are powered via a 12-volt power source, often connected to a vehicle battery or integrated power pack. These are common on ATV weed sprayers and tow-behind sprayers.
Great for: Versatility and medium-large property spraying.
Powerful enough to run boom kits or long hoses.
Common features: Durable pumps, long hoses, and heavy-duty tanks.
4. ATV Weed Sprayer
An ATV weed sprayer is designed to be mounted on the rear rack of a quad bike or utility vehicle. Some versions are tow-behind style, while others are tank-only units.
Perfect for: Properties with rough terrain where maneuverability is essential.
Look for: Secure mounting brackets and anti-spill lids.
Popular sizes: 50L–100L tanks.
5. Tow-Behind Weed Sprayers
These are compact weed sprayer trolleys or small trailers you pull with a quad bike or ride-on mower. They're great if you want something larger than a handheld unit but more affordable than a full-size sprayer trailer.
Great for: Acreage, sports fields, and vineyards.
Comes with: Boom arms, spray guns, and large-capacity tanks.
Check for: Quality wheels and strong hitch points.
6. Boom Sprayer Kit
A weed sprayer boom spreads the spray over a wide path, helping cover large areas quickly. Boom kits are often added to trailer or ATV sprayers.
Perfect for: Uniform spraying across driveways, paddocks, and garden beds.
Width options: 1m to 3m booms.
Buy separately or as a kit with tank and pump.
7. Trolley Weed Sprayers
A weed sprayer trolley is essentially a sprayer mounted on wheels, making it easy to maneuver without needing a ride-on or vehicle.
Great for: Suburban yards and nurseries.
Features: Handheld wands, variable nozzles, and compact designs.
Ideal tank size: 20–50 litres.
Key Features to Look For
No matter which type of weed spray unit you choose, make sure to consider the following:
- Tank Capacity: Ranges from 5L (handheld) to over 200L (weed sprayer 100L is a popular middle ground).
- Pump Strength: Look for pumps that deliver 60–100 PSI for consistent spraying.
- Material Quality: UV-stabilised polyethylene tanks and corrosion-resistant fittings are a must.
- Boom or Wand: Boom kits are better for large areas, while wands offer spot control.
- Hose Length: Longer hoses (5m–10m) offer more flexibility for hard-to-reach spots.
- Ease of Maintenance: Look for quick-connect fittings and replaceable filters.

Weed Sprayer Kits
