Keeping weeds under control on your property is no easy task—especially if you're managing a few acres, a farm, or even a large backyard. The right weed sprayer can make the job faster, easier, and a whole lot more efficient. Whether you’re chasing a weed sprayer for an ATV, a battery-powered unit, or even a weed sprayer trailer, there’s a unit out there made to suit your needs.

In this guide, we’ll walk you through everything you need to know to pick the perfect weed spray unit, including the different types, tank sizes, power options, boom kits, and attachments. We’ll also highlight where to find weed sprayers for sale across Australia and what to look for before making your final choice.

 

Types of Weed Sprayers in Australia

Before choosing a sprayer, it helps to understand the main types available:

1. Backpack or Handheld Weed Sprayers

Best for small gardens, footpaths, and spot spraying. These are usually manual or battery-powered and come in tank sizes from 5L to 20L.

2. ATV Weed Sprayers

If you’ve got a quad bike, you’ll love the convenience of a weed sprayer for ATV setups. These typically mount on the rear rack and come with a boom kit or wand for spraying while you drive.

Popular tank sizes range from 50L to 100L, and they’re great for covering paddocks, fencelines, and firebreaks.

3. 12V or Battery-Powered Weed Sprayers

A 12V weed sprayer or battery-operated weed sprayer is ideal for small to medium areas where portability is key. These are great for people who want less manual labour and more efficiency.

They can be mounted on trailers, mowers, or used as stand-alone units. Look for weed sprayer 12 volt units with durable pumps and solid tank construction.

4. Ride-On Mower Weed Sprayers

Need to multitask? A weed sprayer for ride on mower lets you cover ground while mowing. These units are usually small trailers or rear-mounted kits designed for ease of use and accessibility.

5. Trailer Weed Sprayers

If you’re tackling a large property or commercial job, a weed sprayer trailer is your best bet. These come with large sprayer tanks and pumps (typically 100L to 300L or more) and are towed behind tractors, ATVs, or mowers.

You’ll find these especially handy if you want to mount a weed sprayer boom kit for wide coverage.

 

Key Features to Look For

When buying a weed spray unit, consider the following:

✅ Tank Capacity

• Small jobs: 5L–20L
   

• Medium acreage: 50L–100L
   

• Large properties: 150L+
   

Always get a tank that's UV-stabilised and chemical-resistant.

✅ Pump Type

• Diaphragm or roller pumps are most common.
   

• Look for pressure ratings that match your needs (higher pressure = finer mist and longer reach).
   

✅ Power Source

• Battery powered weed sprayers offer silent operation and portability.
   

• 12V weed sprayers run off your vehicle's power system (like a quad bike or mower).
   

• Some high-end units can even be hooked up to tractors.
   

✅ Boom or Wand?

• A boom sprayer kit is perfect for even coverage over wide areas like pastures and driveways.
   

• A hand wand is great for spot spraying or hard-to-reach places.
   

 

Choosing a Sprayer by Vehicle or Use Case

Here’s how to match a sprayer to your specific setup:

????️ Weed Sprayer for ATV or Quad Bike

If you’ve got a quad, a weed sprayer for quad bike setups is a no-brainer. These units mount easily and often include a 12V pump that connects directly to the ATV battery. Add a boom kit to cover wide swaths or use a handheld lance for targeted spraying.

Pro tip: Look for ATV sprayers with a 100L tank and a reliable pressure switch system to avoid pump burnout.

???? Weed Sprayer Battery Powered

Prefer to avoid wiring and want portability? Go for a battery operated weed sprayer. These often come in wheeled designs or lightweight backpack models with rechargeable lithium batteries. No cords, no fuss.

Perfect for gardeners or suburban block owners.

???? Weed Sprayer for Tractor

For farms and big jobs, a weed sprayer for tractor with a tow-behind tank is ideal. Look for units with large-capacity tanks (200L+), tough chassis, and boom kits that can cover several metres per pass.

You’ll also want a high-flow pump to maintain consistent pressure across multiple nozzles.

???? Weed Sprayer for Ride On Mower

If your ride-on has a hitch, you can easily tow a small sprayer trailer or mount a compact 12V unit. These are great for medium-sized lawns and rural blocks.

Look for weed sprayers for large areas that balance size with manoeuvrability.

 

Weed Sprayer Boom Kits: Worth It?

Yes — if you're spraying large areas like paddocks, orchards, or roadsides, a weed sprayer boom kit can save you time and energy. These attachments create a wide spray pattern (up to 3m or more) and are usually height-adjustable.

Make sure the boom is foldable or detachable for easy storage and transport.

 

Complete Units: Weed Sprayer Tank and Pump

If you're after a full system, look for a weed sprayer tank and pump combo. These usually include:

• Heavy-duty plastic tank (UV-resistant)
   

• 12V or battery pump (3–5L/min flow rate or higher)
   

• Pressure gauge and regulator
   

• Hose, lance, and spray nozzles
   

Most setups are plug-and-play and can be mounted onto utes, trailers, or ATVs.
