But with so many options – weed sprayers for tractors, quad bikes, ride-on mowers, ATVs, and even battery-powered weed sprayers – it can get confusing. This guide will break it all down so you can pick the perfect setup for your property.
Why You Need a Weed Sprayer
Manually pulling weeds might work in small gardens, but when you’ve got paddocks, fence lines, driveways, or gravel paths to manage, you need something more efficient. A weed sprayer unit saves you time, reduces chemical waste, and ensures even coverage.
You’ll also be doing your back a favour—no more lugging around heavy pump bottles or kneeling for hours. Just load up, switch it on, and get spraying.
Types of Weed Sprayers
Let’s look at the most popular weed sprayer units in Australia and how they work.
1. Handheld and Backpack Weed Sprayers
These are ideal for small-scale spraying, spot treatments, or garden beds. While not the focus of this guide, they’re handy for tight spaces and easy transport.
2. Weed Sprayer Tank and Pump Units
These are the core of any serious spraying setup. You’ll find options ranging from 50L to over 200L. A weed sprayer tank can be mounted on ATVs, trailers, or even ride-on mowers.
Look for a model that includes:
- A reliable pump (12V or battery-powered)
- Pressure gauge and regulator
- Wand for spot spraying
- Hose reel (for bigger areas)
3. ATV Weed Sprayers
Got a quad bike? Then a weed sprayer for ATV use is your best mate. These compact units strap securely to the back of your four-wheeler and are powered by a 12V connection from your ATV battery.
ATV weed sprayers are great for:
- Fence lines
- Paddocks
- Narrow tracks
- Firebreaks
Most models come with a spray wand and optional boom kits if you want to cover more ground per pass.
4. Battery-Powered Weed Sprayers
No 12V setup? No worries. A battery-operated weed sprayer is ideal for ride-on mowers, small trailers, or standalone operation. These models run off rechargeable lithium or lead-acid batteries and are perfect when you need portability and simplicity.
Pros:
- No wiring needed
- Quiet operation
- Plug-and-spray convenience
Perfect for hobby farms or suburban properties with a lot of garden beds and borders.
5. Trailer Weed Sprayers
If you’ve got serious acreage, a weed sprayer trailer is a must. These are tow-behind units with large tanks (up to 400L+), heavy-duty pumps, and boom sprayers for wide coverage.
They're ideal for:
- Broadacre spraying
- Orchards and vineyards
- Pasture management
You can tow them behind a ride-on mower, ATV, or tractor, making them incredibly versatile.
6. Weed Sprayers for Tractors
For large-scale farms, a weed sprayer for tractor use is the most powerful option. These units often have boom kits that span several metres and high-pressure pumps for wide and even application.
They’re not overkill if you're running:
- A farm
- A large rural property
- A business maintaining large green spaces
Key Features to Consider
When browsing weed spray units for sale, don’t just go for the biggest tank or cheapest price. Consider:
✅ Tank Size
Think about how much area you need to spray. Common tank sizes include:
- 50L–100L: Suitable for small properties
- 100L–200L: Mid-size acreage
- 200L+: Large rural properties and commercial use
✅ Pump Power
- 12V weed sprayers are great for light to medium jobs.
- High-pressure pumps or diaphragm pumps are better for boom spraying and wide coverage.
- Battery-powered models offer convenience but might have less pressure.
✅ Spraying Method
- Boom kits are ideal for large open areas.
- Spot spraying wands are better for targeted applications along fence lines, gardens, or pathways.
✅ Mounting Option
Choose between:
- Tow-behind trailer sprayers
- Mounted sprayers for ATVs or ride-ons
- 3-point hitch models for tractors
✅ Durability & Materials
Go for UV-resistant poly tanks, stainless steel or brass fittings, and corrosion-resistant pumps – especially if you’re using herbicides or weed killers long-term.
Popular Weed Sprayer Setups
Here are some common setups people across Australia use:
???? Weed Sprayer for Ride-On Mower
Perfect for hobby farms or large lawns. Mount a 100L tank on the rear tray, powered by a 12V or battery-operated pump. Add a boom if you want wider spray coverage.
???? Weed Sprayer for Quad Bike
Compact, easy to use, and ideal for rough terrain. A 50L tank with a spot-spraying wand gets into those tricky areas along fence lines or paddocks.
???? Weed Sprayer for Tractor
A 300L tank paired with a 3-metre boom kit is great for serious landowners. Cover wide areas in fewer passes and reduce chemical use with better efficiency.
???? Weed Sprayer Trailer
If you need portability without mounting to a vehicle, trailer options with 200L+ tanks and battery-powered pumps offer flexibility and power.

Tips for Using Your Weed Sprayer
- Always read the label on your herbicide. Different weeds require different solutions.
- Calibrate your sprayer before starting – this ensures you're not over- or under-applying.
- Clean your equipment thoroughly after each use. Herbicides can damage parts if left sitting too long.
- Spray during calm, dry conditions to avoid drift and waste.
- Wear protective gear – gloves, goggles, long sleeves – especially if using concentrated chemicals.
