In this guide, we’ll break down the different types of weed sprayers, their key features, and how to pick the best one based on your needs—whether it’s battery operated, ATV-mounted, or a weed sprayer trailer for large-scale spraying.
What Is a Weed Sprayer and Why Do You Need One?
A weed sprayer is a device designed to apply herbicides evenly across lawns, gardens, driveways, or farmland. They help save time, reduce manual labour, and ensure efficient coverage. The best part? No more spot-pulling weeds under the Aussie sun.
You’ll find sprayers in all shapes and sizes—from weed sprayer tanks you carry on your back, to larger weed sprayer trailer units for ride-on mowers or tractors.
Types of Weed Sprayers: Which One Suits Your Property?
Let’s dive into the most common types of weed spray units you’ll come across in Australia:
1. Handheld and Backpack Sprayers
Ideal for small gardens, pathways, and precision work. These typically come with a manual pump or are battery powered.
- ✅ Best for spot spraying
- ✅ Lightweight and easy to store
- ❌ Not ideal for large areas
2. 12V Weed Sprayers
The classic weed sprayer 12 volt system is one of the most popular choices in rural Australia. These are compact units with a weed sprayer tank and pump, often powered by a 12V battery—perfect for UTEs, quad bikes, and ride-ons.
- ✅ Great for mid-sized properties
- ✅ Can be fitted to vehicles
- ✅ Precise and consistent spraying
3. ATV Weed Sprayers
An ATV weed sprayer mounts directly to your quad bike, making it easy to cover large areas quickly. You’ll often find these fitted with a weed sprayer boom kit to extend your spray coverage.
- ✅ Perfect for hobby farms and acreage
- ✅ Fast, efficient, and hands-free spraying
- ✅ Optional boom kits for even coverage
4. Trailer Weed Sprayers
If you’ve got lots of land to maintain, a weed sprayer trailer is your go-to solution. These tow-behind units can hold large amounts of spray solution and are built for ride-on mowers or tractors.
- ✅ Best for large properties
- ✅ High-capacity weed sprayer tanks
- ✅ Saves time over large acreage
Key Features to Consider in a Weed Sprayer
Before choosing your weed sprayer, consider these important features:
✅ Tank Size
Tank capacity can range from a few litres to over 200L. If you're covering large acreage, aim for a sprayer with a large weed sprayer tank (100L+). For smaller jobs, 15L-50L is usually enough.
✅ Pump Type
Most modern units use electric diaphragm pumps, especially the 12V weed sprayers. Look for quality brands with reliable pressure ratings.
✅ Power Source
- Battery powered weed sprayers are quiet and cordless—great for small to medium gardens.
- 12V weed sprayers connect to a vehicle or external battery for larger tasks.
✅ Boom Kits
Adding a weed sprayer boom kit helps cover wide areas with fewer passes. Ideal for pastures or large paddocks.
✅ Mounting Style
Choose based on your existing equipment:
- ATV-mounted or quad bike weed sprayers
- Ride-on mower sprayers
- Tractor-mounted or tow-behind sprayers

Got Large Areas? Go Boom or Go Home
If you're dealing with paddocks, pastures, or driveways, a weed sprayer for large areas should be top of mind. Boom sprayers offer the best efficiency, letting you cover wide strips of land in one pass. Pair that with a high-capacity tank and pump, and you're saving serious time.

Final Thoughts: Which Weed Sprayer Is Right for You?
Choosing the right weed sprayer comes down to three things: your property size, your existing equipment, and how often you spray. If you’re just handling a veggie patch, a handheld unit will do. But if you’ve got a few hectares to manage, an ATV weed sprayer or a weed sprayer trailer will make your life a whole lot easier.
No matter what you choose, investing in a quality weed spray unit now will save you hours of backbreaking work down the track. And let’s face it—spraying weeds with a quad bike is a lot more fun than pulling them by hand.
