With so many types of weed sprayers on the market – from battery-powered units to ATV sprayers and trailer models – knowing which one to choose can be a bit overwhelming. That’s why we’ve put together this comprehensive guide to help you find the best weed spray unit for your needs. We’ll cover everything from weed sprayer tanks and pumps, to boom kits, power types, and what to look for based on your property size.
Let’s dive in.
Why You Need a Quality Weed Sprayer
No one wants to spend hours battling thistles, bindii, or creeping weeds by hand. A weed sprayer takes the hard work out of the equation, helping you apply herbicides quickly and evenly across your property. The right weed sprayer unit can save you time, reduce chemical waste, and help you tackle everything from small garden beds to sprawling paddocks.
Plus, with so many sprayers now designed for specific vehicles like quad bikes, tractors, and ride-on mowers, it’s never been easier to stay on top of weed control – no matter how much land you’re working with.
Types of Weed Sprayers
Before choosing a sprayer, it’s worth understanding the main types available. The best model for you depends on how large your property is, what kind of weeds you’re dealing with, and how mobile you need to be.
1. Handheld and Backpack Sprayers
Great for small gardens and spot spraying. These aren’t really ideal for big jobs but are handy for around the house or in tighter areas like veggie patches or garden beds.
2. ATV Weed Sprayer Units
If you’ve got a quad bike, an ATV weed sprayer is a perfect match. These units sit securely on the back of your bike and are designed to cover more ground than handheld options. Most come with a 12V pump and spray wand, and some even feature boom kits for wider coverage.
Perfect for small farms, acreage, and hobby farms.
3. 12V Battery-Operated Weed Sprayers
If convenience and quiet operation are your priority, a weed sprayer battery powered model might be the way to go. These run on rechargeable 12-volt batteries and are ideal for light to medium spraying jobs.
Look for options that offer a decent battery life and solid pump pressure – especially if you plan on using it for more than just spot spraying.
4. Tractor and Ride-On Mower Sprayers
For bigger properties, a weed sprayer for tractor or ride-on mower is a top choice. These units often attach to your existing equipment and can be used with boom kits to cover wide swathes of land. They're built for power, efficiency, and covering large areas without having to refill too often.
5. Trailer Weed Sprayers
Need to cover serious ground? A weed sprayer trailer is your best friend. These larger units come with big tanks (often 100L or more), strong pumps, and wide booms. You can tow them behind a quad, ride-on, or small tractor and get the job done fast.
Ideal for professional use or properties over several acres.
Key Features to Look For
Choosing the right weed sprayer for sale comes down to more than just size. Here are the top things to consider when comparing models:
✅ Tank Size
- Small jobs: 5–15L
- Medium jobs: 50–100L
- Large properties: 100L+
Make sure the tank is made from UV-stabilised polyethylene so it won’t degrade in the Aussie sun.
✅ Pump Type
Most weed sprayers use 12-volt diaphragm pumps, which are reliable and chemical-resistant. For better flow rates and pressure, check the litres per minute (LPM) rating.
✅ Boom Kit or Spray Wand?
- Boom kits are great for broad coverage – perfect for paddocks, pastures, and large lawns.
- Spray wands give you precision and control – ideal for spot spraying.
Some sprayers offer both, so you can switch depending on the job.
✅ Power Source
- 12V weed sprayers
- : Connect to your ATV, mower, or tractor battery.
- Battery-operated weed sprayers: Rechargeable and cord-free, great for light to medium spraying.
- Petrol-powered sprayers: More powerful, but noisier and heavier. Best for pro-level spraying or remote areas.
Matching the Sprayer to the Job
Let’s break down what type of weed sprayer unit works best depending on your situation.
???? Spot Spraying
If you only need to hit specific weeds, like those pesky ones popping up along the fence line or driveway, go for:
- Handheld or backpack sprayers
- Battery-operated 12V units with a wand
???? Spraying Large Areas
If you’re dealing with large acreage or broad areas of pasture, opt for:
- Boom sprayers (mounted or trailer)
- Weed sprayers for ride-on mowers
- ATV weed sprayers with wide booms
- Weed sprayer trailers for extra tank capacity
???? Spraying with a Quad Bike or Ride-On
Want to get the job done fast? A weed sprayer for quad bike or ride-on mower can cover lots of ground in minimal time. Look for:
- Compact 12V tanks (50L–100L)
- Secure mounting brackets
- Wand and boom options
???? Spraying with a Tractor
If you’re already using a tractor around the property, consider upgrading with a weed sprayer for tractor. These often include:
- Large tanks (up to 200L or more)
- Boom kits for wide spraying
- PTO or 12V power options

Final Tips Before You Buy
Still not sure which weed sprayer is right for you? Here are a few final tips:
- Don’t undersize your tank. If you’ve got a big property, a larger tank will save you heaps of time refilling.
- Check compatibility with your vehicle. Not all sprayers will mount to every quad, tractor, or mower.
- Choose chemical-resistant materials. Herbicides can be harsh – make sure the pump and hoses are built to last.
- Go for a known brand. It’s worth paying a little extra for reliability, spare parts, and service options.
