Look, nobody likes dragging a wand around for hours, especially when you’ve got acres to cover. I remember my first real attempt at spraying the back forty. It felt like I was doing the world’s most boring marathon, wand in hand, back aching, and the spray pattern looking like a sad, leaky faucet. That’s when the question, ‘can I put a boom on a Fimco sprayer?’ first popped into my head, and honestly, it’s one worth asking if you’re tired of the manual labor.
Fimco makes solid sprayers, no doubt about it. They’re workhorses. But the standard wand setup? It’s fine for a small garden or a few bushes, but for anything bigger, it’s a pain in the neck. A boom sprayer attachment is the obvious next step, turning a chore into something almost… manageable. But it’s not always as simple as just bolting it on.
Making the Switch: Boom Sprayer Compatibility Explained
Alright, let’s get down to brass tacks. You’ve got a Fimco sprayer, likely one of their popular poly tanks on a trailer or ATV mount, and you’re eyeing up those multi-nozzle boom attachments. The big question is always, ‘can I put a boom on a Fimco sprayer?’ The short answer is usually ‘yes,’ but the longer, more honest answer involves a bit more digging. It’s not a one-size-fits-all situation, and slapping on the wrong boom can lead to a whole heap of frustration, leaks, and wasted product.
The key thing to understand is how boom sprayers connect to your sprayer’s pump and tank system. Most aftermarket booms are designed to tap into the sprayer’s existing outlet. This means you’re looking for compatibility in terms of pressure and flow rate. Fimco sprayers, depending on the model, come with different pump sizes – anywhere from a 1.0 GPM diaphragm pump on smaller units to a 5.5 GPM on larger trailer sprayers. Your boom needs to be able to handle the pressure and volume your pump can deliver without overwhelming it or underperforming.
You’ll often see booms advertised with specific GPM or PSI ratings. It’s vital to match these up. If you have a lower-GPM pump, a boom with a massive flow rate is just going to sputter and spray inconsistently, if at all. Conversely, a boom that requires more flow than your pump can provide will result in weak coverage and a lot of headaches.
I made this mistake once, trying to adapt a boom kit meant for a much larger commercial sprayer onto my 25-gallon ATV Fimco. It was a disaster. The pump wheezed, the nozzles dripped, and I ended up spraying half the area manually anyway.
Cost me about $150 for the boom kit and a whole Saturday I’ll never get back.
Beyond the pump, consider the physical mounting points. Fimco sprayers, especially the trailer models, often have a frame or a specific location designed for attachments. You’ll need to see if the boom kit you’re considering has mounting brackets that align with your sprayer, or if you’re willing to do some custom fabrication. Some kits come with universal mounting hardware, which is a lifesaver, but always check the specifications and maybe even dig up some photos or diagrams of how it attaches. Don’t be afraid to call the manufacturer of the boom kit or even Fimco customer support if you’re unsure. A few minutes on the phone could save you days of troubleshooting.
The type of Fimco sprayer you have also matters. A 15-gallon Fimco for a riding mower is a different beast than a 60-gallon trailer sprayer. The larger units are generally much better suited for boom attachments right out of the box because they usually have more solid pumps and frames. For the smaller, cart-style or basic ATV sprayers, you might find yourself needing to reinforce the frame or add extra support to handle the weight and use of a boom, especially on bumpy terrain. It’s all about assessing your current setup and the intended workload.
What to Look for in a Boom Sprayer Attachment
So, you’ve decided you’re going the boom route. Awesome. Now, what the heck should you actually be looking for when you’re browsing options? It’s not just about the number of nozzles; there’s more nuance than that. First off, consider the width of the boom. Do you need to cover a 10-foot swath, or are you trying to blast through a 20-foot field? Wider booms mean fewer passes, obviously, but they also put more strain on your pump and can be harder to maneuver around obstacles. I’ve found that for most typical residential or small farm uses, a 10-12 foot boom is a sweet spot. It’s manageable and covers a decent area without being a monster to handle.

Next up is the nozzle type and spacing. Most boom kits come with a standard set of flat fan nozzles. These are great for herbicides and general spraying. However, if you’re doing something specific, like applying granular fertilizers or needing a different spray pattern for insecticides, you might need to swap out the nozzles. Check if the boom allows for easy nozzle replacement or if it’s proprietary. Also, look at the spacing between nozzles. Closer spacing means more even coverage, especially if you’re dealing with smaller areas or trying to avoid drift. Some booms offer adjustable spacing, which is a nice bonus if you use your sprayer for various tasks.
Material and build quality are also huge. You’re going to be banging this thing around, exposing it to chemicals, sun, and probably the occasional tree branch. Look for booms made from sturdy materials like powder-coated steel or heavy-duty aluminum. Avoid anything that feels flimsy or looks like it’s made from thin, stamped metal. I once bought a ‘budget’ boom that looked decent online, but when it arrived, the metal was so thin I could bend it with my bare hands. It lasted about three applications before a minor bump with a fence post snapped one of the boom arms clean off. Lesson learned: you often get what you pay for here.
Then there’s the fold-away mechanism. This is important for storage and transport. Does the boom fold up neatly against the sprayer, or does it stick out awkwardly? Some booms have manual folding mechanisms, while others are spring-loaded or even hydraulic (though that’s rare on aftermarket kits for Fimco). A good folding system makes a massive difference in usability. I’ve seen some setups that require a wrestling match to fold down, and others that just click into place. For me, anything that adds more than 30 seconds to the setup or takedown time is a demerit. My back isn’t getting any younger, and neither is my patience.
Finally, consider the spray pattern of the nozzles themselves. While most booms come with standard flat fans, some offer options like low-drift nozzles or even cone sprayers. If you’re spraying near sensitive areas or dealing with windy conditions, investing in low-drift nozzles can save you a lot of grief and potential damage to neighboring plants or crops. It’s a small upgrade that can pay big dividends in terms of precision and effectiveness. Always read the product descriptions carefully, and don’t hesitate to look up reviews specifically about the nozzle performance.
Common Mistakes When Attaching a Boom to a Fimco Sprayer
Alright, let’s talk about screw-ups. Because trust me, I’ve made my fair share.
When you’re trying to figure out if you can put a boom on a Fimco sprayer, it’s easy to get excited and overlook the details that really matter. One of the most common blunders is underestimating the weight and use a boom adds. These things, especially the wider ones, can act like a big lever arm.
If you’re mounting it onto a lighter-duty trailer or ATV rack that wasn’t designed for that kind of stress, you can end up bending frames, cracking plastic, or even causing your entire sprayer to tip over. I saw a buddy do this with his smaller Fimco ATV sprayer; a slight bump on a rutted trail and the boom, poorly secured, tore right through the plastic fender it was weakly attached to. It was a mess.
Another huge mistake is ignoring the plumbing. It’s not just about connecting the boom’s inlet to your sprayer’s outlet. You need to think about the material compatibility of any adapters or hoses you use. Many common spray chemicals are corrosive. Using the wrong type of plastic or rubber for your fittings can lead to leaks and premature failure. I learned this the hard way with a cheap hose adapter that swelled up and split after just a few uses with a 2,4-D mix. It cost me about $30 in lost herbicide and a good hour of cleaning up the mess. Stick to fittings specifically rated for agricultural chemical use. Brass or high-quality reinforced PVC are usually your best bet.
People also often forget about the pressure drop. When you add a boom with multiple nozzles, you’re increasing the demand on your pump. If your pump is already at its limit, or if your hoses and fittings are too restrictive, you’ll see a significant pressure drop at the nozzles. This means less effective spraying.

Some folks just crank up the engine throttle to compensate, but that can overheat and damage your pump in the long run. It’s better to make sure your pump is adequately sized for the boom you choose. If your Fimco has a basic 12V pump, a wide boom with many nozzles might be a stretch.
You might need to upgrade the pump or choose a narrower boom.
Here’s a contrarian take for you: some people obsess over getting the widest boom possible. They think bigger is always better. I disagree, especially for most home or hobby farm users. A super-wide boom (say, 20 feet or more) is a nightmare to maneuver around trees, fence posts, buildings, or even just tight corners in a field. It’s also much more susceptible to damage from hitting obstacles. Unless you’re spraying a perfectly clear, massive open field, you’re likely going to spend more time fighting with a giant boom than you save by covering more ground per pass. For most of us, a 10-15 foot boom is far more practical and less stressful.
Finally, and this one really grinds my gears, is the failure to properly calibrate. People just bolt on a boom and expect it to work perfectly. But nozzle wear, pressure fluctuations, and varying speeds all affect the application rate. You must calibrate your boom sprayer. This involves measuring how much liquid you’re applying over a set area at your typical operating speed. Online resources and many sprayer manuals offer guides on how to do this. Without calibration, you risk under-applying (ineffective treatment) or over-applying (wasting product and potentially damaging crops or the environment). It’s a simple process that’s often skipped, and it’s a massive mistake.
Real-World Use and Practical Tips
Okay, so we’ve established that, yes, you can often put a boom on a Fimco sprayer, and here’s what to look for and what to avoid. Now, let’s talk about actually using the thing. The biggest advantage, as we’ve harped on, is efficiency. Covering ground is so much faster. What used to take me an hour with a wand might now take 15-20 minutes with a boom on my Fimco trailer sprayer. This is particularly true for tasks like spot-treating large areas of weeds or applying pre-emergent herbicides across a driveway or field. It makes a job that felt like a weekend chore feel more like an afternoon task.
One practical tip I’ve learned is about boom height adjustment. Most booms have some way to adjust their height off the ground. This is NOT just about aesthetics; it’s important for effective spraying and minimizing drift. For herbicides, you generally want the nozzles about 18-24 inches off the ground, depending on the nozzle type and spray angle. This makes sure good overlap of the spray patterns from adjacent nozzles without being so high that wind can easily blow your spray off target. If you’re spraying something like a liquid fertilizer, you might need a different height to make sure it gets to the root zone. Always check the recommendations for the specific chemical you are applying.
Another tip relates to boom maintenance. After every use, you must flush your boom sprayer thoroughly. Chemicals, especially herbicides, can be incredibly damaging to the nozzles and boom materials if left to sit. Use clean water, run it through the system, and make sure to get water through each nozzle. Some people like to add a sprayer cleaning solution to the water for a more thorough clean, especially if they’re switching from herbicides to insecticides or fungicides. Don’t forget to flush the tank and pump as well. This simple step will dramatically extend the life of your boom and your sprayer.
When you’re out in the field, pay attention to your speed. This is where calibration really comes into play. Driving too fast means the liquid doesn’t have enough time to be deposited properly, leading to uneven coverage and potentially missing spots. Driving too slow can lead to over-application, which can damage your plants or waste product. I tend to use a GPS speed tracker on my phone or ATV to maintain a consistent speed. It sounds high-tech, but it’s really just about consistency. Aim for the speed that your calibration indicated. If you don’t have a specific speed recommendation, a slow, steady walking pace (around 3-4 mph) is often a good starting point for many boom applications.
Finally, consider storage. When you’re done and the boom is cleaned, how are you going to store it? (See Also: Can I Spray Latex Paint With My Wagner Power Sprayer )
A lot of aftermarket booms are designed to fold up, but they can still be bulky. If you have a trailer sprayer, the boom might just fold up and stay attached, which is convenient.
For ATV or cart sprayers, you might need to remove it for storage to save space. Some people build simple racks or stands to hold their booms when they’re not in use. Protecting the nozzles from physical damage and UV exposure will help them last longer.
I’ve seen folks just leave them exposed to the elements, and then wonder why their spray patterns are all messed up by next season.
Faq: Your Burning Questions About Fimco Booms Answered
Can I Attach a Boom Sprayer to Any Fimco Sprayer?
While many Fimco sprayers are compatible with aftermarket boom attachments, it’s not a universal ‘yes.’ You need to consider your specific Fimco model’s pump capacity (GPM and PSI), the sprayer’s frame strength, and the physical mounting points available. Smaller Fimco sprayers with lower GPM pumps might struggle to effectively power wider booms, and their frames may not be solid enough without reinforcement.
What Is the Typical Spray Width of a Boom Attachment for a Fimco Sprayer?
Boom sprayers come in various widths, but for Fimco sprayers commonly used on ATVs or small trailers, you’ll most often find options ranging from 4 feet to 12 feet. Wider booms, like 15-20 feet, are available but are usually better suited for larger, more powerful sprayer systems and open fields, as they can be harder to maneuver.
Do I Need to Upgrade My Fimco’s Pump to Use a Boom Sprayer?
It depends on your current Fimco pump and the specifications of the boom attachment. If you have a higher-GPM pump (e.g., 4.0 GPM or higher) on your Fimco, it can likely handle most standard aftermarket booms. However, if you have a smaller pump (1.0-2.2 GPM) and are looking at a wide boom with many nozzles, you might experience weak performance or need to consider a pump upgrade or a narrower boom.
How Do I Connect a Boom Sprayer to My Fimco Sprayer’s Plumbing?
Typically, boom sprayers connect to the sprayer’s pump outlet. You’ll usually need to adapt your sprayer’s outlet fitting to match the inlet fitting of the boom kit. This often involves using specific hoses and adapters. Make sure all fittings and hoses are made of chemical-resistant materials and are rated for the pressure and flow your sprayer can produce. Always consult the manuals for both your Fimco sprayer and the boom kit.
Will a Boom Sprayer Affect My Fimco Sprayer’s Stability?
Yes, a boom sprayer can definitely affect your Fimco sprayer’s stability, especially if it’s mounted on an ATV or a smaller trailer. The added weight and use of the boom, particularly when extended, can increase the risk of tipping, especially on uneven terrain or during sharp turns. Make sure the boom is securely mounted to a sturdy part of the sprayer’s frame and consider any weight distribution implications.
Verdict
So, to circle back to that burning question: can I put a boom on a Fimco sprayer? For most folks with a Fimco, the answer is a resounding ‘yes,’ but with the understanding that you’ve got to do your homework. It’s not a plug-and-play situation for every single Fimco model out there, and shortcuts in choosing or installing the right boom can cost you time, money, and a whole lot of frustration. My own experience with that ill-fated budget boom taught me the hard way that quality and compatibility are king.
Think about what you’re spraying, how much ground you need to cover, and the specific capabilities of your Fimco sprayer. Don’t just buy the biggest, widest boom you can find; consider the maneuverability and potential strain on your equipment. Always prioritize chemical-resistant fittings and a sturdy build. If you do your due diligence, you’ll find that adding a boom can transform your spraying tasks from a back-breaking chore into a far more efficient operation.
Honestly, the biggest hurdle isn’t usually the Fimco sprayer itself, but finding the right boom kit that plays nice with your setup and your specific needs. Take the time to research, measure twice, and maybe even call a support line before you buy. Your future self, with a pain-free back and perfectly sprayed fields, will thank you.
