In this guide, we’ll break down the different types of weed sprayers, their features, and how to choose the perfect setup based on your land size, terrain, and workload. Whether you're looking for a weed sprayer for large areas or something compact and convenient, we've got you covered.
Why Use a Weed Sprayer?
A weed sprayer delivers herbicide efficiently and evenly, helping you tackle invasive weeds before they get out of control. Compared to hand-pulling or spot-treating with a small spray bottle, a dedicated weed spray unit lets you cover more ground faster, with better consistency and less waste.
From gardening enthusiasts to farmers and lifestyle property owners, everyone who battles weeds can benefit from having the right gear in their shed.
Different Types of Weed Sprayers
There are several types of weed sprayers available, each with its own strengths. Here's a rundown to help you understand what's what:
1. Weed Sprayer Trailer / Trailer Mounted Weed Sprayer
Perfect for large properties and wide-open areas, a weed sprayer with trailer or a trailer-mounted weed sprayer lets you tow your tank and boom behind a quad bike, UTV, or small tractor. These sprayers typically have large tanks—often up to 100L or more—making them ideal for covering serious ground.
Pros:
- Great for large areas
- Can be paired with a weed sprayer boom for wide spray coverage
- Reduces refills with larger weed sprayer tank capacity
Best for: Paddocks, farms, vineyards, or anyone needing to spray over several hectares.
2. Weed Sprayer ATV / Weed Sprayer for Quad Bike
These are designed to mount on your ATV or quad bike, making them incredibly convenient and mobile. They're more compact than trailers but still offer good tank capacity (often around 50L to 100L), and they can handle rugged terrain with ease.
Pros:
- Easy to maneuver
- Faster than trolley or handheld options
- Compatible with weed sprayer boom kits for broader reach
Best for: Hilly terrain, rough paddocks, or areas not easily accessed by vehicles.
3. Battery-Powered Weed Sprayer / Weed Sprayer Battery / Weed Sprayer 12V
Gone are the days of pumping manually. A battery-powered weed sprayer (often a weed sprayer 12V) offers consistent pressure with minimal effort. These can be carried as backpacks, mounted on trolleys, or fitted into a small utility vehicle.
Pros:
- No pumping required
- Consistent spray pressure
- Lightweight and portable options available
Best for: Small to medium gardens, urban properties, and users who prefer a quieter and easier spraying experience.
4. Weed Sprayer Trolley
A weed sprayer trolley is essentially a wheeled unit that carries your tank and pump for easy mobility. They’re a great middle-ground option—larger than a handheld sprayer, but more portable than a trailer setup.
Pros:
- Easy to move around
- Suitable for moderate-sized areas
- Works well on flat ground or pathways
Best for: Suburban gardens, orchards, or landscaped areas.
Key Components of a Weed Spray Unit
Regardless of type, a quality weed sprayer unit should include the following:
✔️ Tank Capacity
The bigger the tank, the less often you’ll need to refill. For smaller properties, a 15L–25L tank might do the job. But for larger areas, look for weed sprayers 100L or more.
✔️ Pump Power
A strong pump ensures even distribution of spray and better pressure. 12-volt pumps are common in battery-powered and trailer units, offering good flow without manual labor.
✔️ Boom or Wand
- A weed sprayer boom covers a wide strip in one pass—perfect for paddocks or driveways.
- A spray wand or lance gives you precise control for spot treatment or hard-to-reach areas.
✔️ Kit Options
Many suppliers offer weed sprayer kits that include tanks, pumps, hoses, booms, and mounts. Choosing a complete weed sprayer tank and pump kit can simplify your setup.
Choosing the Right Weed Sprayer for Your Needs
Here’s a quick guide based on property size and terrain:
| Property Size | Recommended Sprayer Type |
| Small gardens | Handheld or battery-powered backpack sprayer |
| Medium lawns/paths | Weed sprayer trolley or small battery sprayer |
| 1–5 acres | ATV sprayer or towed weed sprayer |
| 5+ acres | Trailer-mounted weed sprayer with boom attachment |
Also, consider your terrain. If your land is hilly or uneven, an ATV-compatible unit offers better manoeuvrability than a trailer.
