7 Pieces of Gear for Mounting Sprayers on Utility Vehicles

Transforming a standard utility vehicle into an efficient spraying rig is one of the smartest upgrades a hobby farmer can make. However, simply throwing a plastic tank into the cargo bed and hoping for the best is a recipe for chemical spills, damaged suspension, and uneven application. Having the right mounting gear ensures the setup remains safe, stable, and highly productive throughout the growing season.

Assessing Your Utility Vehicle Cargo Capacity

Utility vehicles are workhorses, but they have strict payload limits that must never be ignored. Before purchasing any spraying equipment, locate the vehicle manufacturer’s manual to find the maximum cargo bed capacity. This rating includes not just the weight of the tank, but also the operator, fuel, tools, and the mounting hardware itself.

Overloading a UTV compromises steering responsiveness, ruins the suspension, and increases braking distances. A vehicle carrying too much rear weight can easily tip backward when climbing a steep farm track or ditch bank. Always leave a safety margin of at least 15 to 20 percent below the maximum rated capacity to account for rough terrain.

Measure the physical dimensions of the cargo bed carefully. Pay close attention to the wheel well intrusions and the height of the tailgate. A tank that is too wide will not sit flat on the bed floor, which prevents proper securing and raises the center of gravity dangerously high.

Understanding Liquid Weight and Vehicle Balance

Liquid weight is dynamic and behaves differently than solid cargo like firewood or gravel. Water weighs approximately 8.34 pounds per gallon, meaning a modest 25-gallon tank adds over 200 pounds of shifting weight to the vehicle. A larger 50-gallon setup pushes that weight past 400 pounds, which dramatically alters vehicle handling.

As the vehicle turns, accelerates, or brakes, the liquid inside the tank sloshes from side to side. This movement creates kinetic energy that can easily push a light utility vehicle off its intended path or cause a rollover on side slopes. Keeping the tank as full as possible during operation, or using baffled tanks, helps minimize this dangerous fluid movement.

Proper placement is critical for maintaining vehicle balance and traction. Position the tank as low as possible and center it directly over or slightly ahead of the rear axle. This placement distributes the weight evenly across the chassis, keeping the front steering wheels firmly planted on the ground.

Hitch Mount – Fimco 2-Inch Receiver Mount

A hitch mount serves a vital role by moving the sprayer assembly entirely outside the cargo bed. This configuration frees up valuable bed space for carrying hand tools, fencing supplies, or extra chemical jugs during a busy day of pasture maintenance. It also lowers the loading height, making it easier to fill and service the sprayer.

The Fimco 2-Inch Receiver Mount is the ideal choice for this task due to its rugged steel construction and direct compatibility with standard UTV receivers. It features a durable powder-coat finish that resists chemical corrosion and harsh outdoor weather. The mount holds the sprayer securely, preventing the bouncing and swaying that common DIY hitch setups suffer from.

• Receiver Size: Fits standard 2-inch receivers
• Material: Heavy-duty welded steel
• Finish: Corrosion-resistant powder coat

Before purchasing, consider the added length this mount introduces to the utility vehicle. The extended overhang reduces the departure angle, meaning the mount can scrape the ground when crossing deep ditches or climbing steep banks. Regular inspections of the hitch pin and receiver weld points are necessary to ensure no stress cracks develop.

This mount is perfect for landowners with flat to gently rolling acreage who need to maximize their cargo bed space. It is not suitable for operators working on highly rugged, terraced, or steep terrain where ground clearance is the primary concern.

Ratchet Straps – SmartStraps Heavy Duty Straps

Heavy polyethylene tanks are notoriously slick and difficult to hold in place on a moving vehicle. High-quality ratchet straps are the primary defense against a tank sliding, tipping, or launching out of the bed during sudden stops. Rope or cheap bungee cords simply cannot handle the dynamic forces of shifting liquid weight.

The SmartStraps Heavy Duty Straps stand out because of their proprietary SmartWeb technology, which offers superior abrasion resistance compared to standard webbing. The padded, oversized ratchet grips allow for comfortable tightening even when wearing thick work gloves. The high-visibility color ensures the straps are easy to inspect for wear and tear before heading out to the field.

• Load Limit: 1,000 lbs working load limit (3,000 lbs break strength)
• Webbing: SmartWeb abrasion-resistant technology
• Hooks: Non-marring coated S-hooks

Plastic tanks flex and contract as they are filled and emptied. This means the straps must be checked and retightened after the first few minutes of driving to prevent slack from developing. Store these straps in a dry, dark toolbox when not in use, as prolonged UV exposure degrades the synthetic fibers over time.

These straps are an absolute necessity for anyone hauling a 25- to 50-gallon tank in a utility bed. They are overkill for small 10-gallon spot sprayers that can be bolted down directly, but they are cheap insurance for larger, high-value setups.

Wiring Harness – Fimco 12-Volt Wire Harness

A dedicated wiring harness delivers clean, consistent DC electrical power from the utility vehicle battery to the sprayer pump. Attempting to run a pump with flimsy speaker wire or temporary alligator clips leads to voltage drops, blown fuses, and potential electrical fires. A proper harness ensures the pump runs at its rated pressure for consistent chemical application.

The Fimco 12-Volt Wire Harness is designed specifically for agricultural utility vehicles, featuring heavy-gauge wire that prevents power loss over long distances. It includes a built-in, weather-resistant on/off switch that can be positioned within easy reach of the driver. The integrated fuse holder protects both the pump motor and the vehicle’s electrical system from sudden power surges.

• Wire Gauge: 16-gauge heavy-duty wire
• Safety: Inline fuse protection (15-amp)
• Connectors: Quick-disconnect 2-pin plugs

When installing this harness, route the wire carefully along the vehicle frame, securing it with zip ties. Keep the wire away from hot exhaust pipes, sharp metal edges, and moving suspension components that could pinch or melt the insulation. Ensure the quick-disconnect plugs are clean and free of dirt before making connections.

This harness is the perfect solution for anyone running a standard 12-volt diaphragm pump up to 4.5 GPM. It is not designed for heavy-duty commercial pumps that require direct alternator connections or pull more than 20 amps of current.

Boom Bracket – Chapin Universal Mounting Kit

A boom bracket holds the spray boom at a precise height and angle behind the utility vehicle. Without a sturdy bracket, the boom will bounce, sag, or misalign, resulting in uneven spray patterns and missed weeds. The bracket must withstand constant vibration while traveling over bumpy pastures and rough fields.

The Chapin Universal Mounting Kit is highly recommended for its exceptional versatility and robust steel build. The pre-drilled slot patterns allow it to mount to almost any UTV tailgate, bed rail, or cargo box without extensive modification. It provides a rock-solid foundation that keeps the boom level, even when driving over rutted ground.

• Compatibility: Fits most standard UTV tailgates and beds
• Material: Heavy-gauge powder-coated steel
• Adjustability: Multi-position height adjustment slots

Proper installation requires aligning the bracket so the spray nozzles sit at the manufacturer’s recommended height above the target weeds. If the bracket is mounted too low, the spray patterns will not overlap correctly; if too high, wind drift becomes a major problem. Periodic tightening of the mounting bolts is necessary to combat the effects of engine and trail vibration.

This kit is ideal for DIY-minded hobby farmers who want to adapt an existing spray boom to a new or different utility vehicle. It is not necessary for those using boomless nozzles that mount directly to the sprayer tank frame.

Utility Bed Mat – Dee Zee Heavy Duty Rubber Mat

A utility bed mat provides the friction needed to keep a heavy plastic sprayer tank from sliding around on slick plastic or metal beds. Shifting cargo can damage the vehicle bed sides, strain the tie-down straps, and pull electrical wires loose. The mat also acts as a shock absorber, protecting the sprayer pump from harsh trail vibrations.

The Dee Zee Heavy Duty Rubber Mat is constructed from high-density, fiber-reinforced rubber that will not tear, crack, or rust. Its textured surface prevents the tank from sliding even when wet with chemical overspray or rainwater. The thick rubber also dampens the constant humming noise generated by 12-volt sprayer pumps during operation.

• Thickness: 3/8-inch heavy-duty rubber
• Material: High-density, fiber-reinforced compound
• Surface: Non-slip textured finish

Because these mats are thick and heavy, they must be trimmed with a utility knife to fit the specific contours of the UTV bed. Over time, chemical spills and moisture can collect underneath the mat, potentially causing rust on steel beds. It is wise to remove the mat once a season to clean and dry the cargo bed floor.

This mat is highly recommended for any farmer carrying a bed-mounted sprayer on a regular basis. It is not necessary if the sprayer is permanently bolted to a dedicated metal skid frame that is anchored directly to the vehicle chassis.

Hose Reel – Coxreels Hand Crank Hose Reel

A hose reel solves the frustrating problem of tangled, kinked, and damaged spray hoses. Leaving a long hose coiled loosely in the UTV bed leads to punctures from tools, melting from exhaust heat, or entanglement in the vehicle tires. A quality reel keeps the hose organized, protected, and ready to deploy at a moment’s notice.

The Coxreels Hand Crank Hose Reel is the gold standard for small-scale operations due to its all-steel construction and brass swivel inlet. The CNC-spun discs have rolled edges that prevent the hose from chafing or cutting during winding. The durable powder-coat finish ensures the reel survives years of exposure to corrosive agricultural chemicals.

• Capacity: Holds up to 100 feet of 3/8-inch hose
• Frame: All-steel "A" frame design
• Swivel: Leak-free brass swivel joint

Mounting the reel securely requires a flat, solid surface, such as the sprayer skid frame or the UTV bed floor. Always drain the pressure from the spray line before winding the hose back onto the reel to prevent the hose from expanding and binding. Lubricate the brass swivel joint annually to maintain a leak-free seal.

This reel is a fantastic investment for farmers who do extensive spot-spraying along fence lines, ditch banks, or orchard rows. It is unnecessary for those who rely solely on broadcast boom spraying and do not use a spray gun.

Remote Switch – Fimco Wireless Remote Control

A remote switch allows the operator to control the sprayer pump from the driver’s seat without routing long, messy wires into the cab. This is especially useful for modern UTVs with fully enclosed cabs where running physical wires is difficult or impossible. It improves safety by letting the driver quickly shut off the pump if an obstacle or bystander suddenly appears.

The Fimco Wireless Remote Control offers a simple, plug-and-play solution that connects directly between the pump and the power source. The compact key fob transmitter can be clipped to the steering wheel or dashboard for instant access. It operates on a reliable radio frequency that works even without a direct line of sight to the receiver.

• Range: Up to 250 feet of wireless range
• Voltage: 12-volt DC operation
• Connectors: Quick-connect terminals for easy installation

The remote transmitter relies on a small coin-cell battery that should be replaced at the start of every spraying season to prevent mid-field failures. If the receiver is mounted inside a metal toolbox or deep within the UTV frame, the wireless range may be slightly reduced. Keep a spare fuse on hand, as the receiver unit contains its own internal protection circuit.

This remote is a must-have for solo operators who need to turn the sprayer on and off frequently while driving. It is not necessary if the sprayer is mounted close enough to the driver’s seat that the manual wire switch is within easy arm’s reach.

Step-by-Step Guide to Securing Your Tank Safely

Securing a sprayer tank requires a systematic approach to prevent accidents on the farm. Begin by placing the utility bed mat flat on the cargo floor, ensuring it is free of dirt and debris. Position the empty sprayer tank on top of the mat, centering the weight over the rear axle. Ensure the tank does not contact the tailgate or side walls directly, as vibration can rub holes in the plastic over time.

Next, thread the heavy-duty ratchet straps through the molded tie-down grooves built into the sprayer tank. Anchor the strap hooks to the UTV’s factory tie-down points, ensuring the straps do not rub against sharp metal edges. Tighten the ratchets evenly on both sides, pulling the tank downward and forward into the bed. The straps should be tight enough to compress the rubber mat slightly, but not so tight that they deform the plastic tank.

Finally, route the electrical wiring harness from the battery to the pump, securing it to the frame with zip ties. Connect the hose lines and check that they are free of kinks and away from moving parts. Before filling the tank with expensive chemicals, fill it with a few gallons of clean water and take a short test drive. Shake the tank vigorously to ensure there is absolutely no shifting or sliding before heading to the field.

Calibrating Your Sprayer for Even Application

Calibration is the most critical step in any spraying operation, yet it is often overlooked by busy hobby farmers. Applying too much chemical wastes money, risks crop damage, and can contaminate the local environment. Applying too little results in poor weed control, requiring a second application that wastes time and fuel.

To calibrate, first measure and mark a test distance of 100 feet on ground similar to the area being sprayed. Drive the UTV over this distance at the exact speed intended for spraying, recording the travel time in seconds. Keep the engine RPMs steady to ensure the electrical system maintains consistent voltage to the pump.

Next, park the vehicle, set the sprayer to the desired operating pressure, and collect the output from a single nozzle in a measuring cup for the exact number of seconds it took to drive the test distance. Multiply this volume by the number of nozzles on the boom to find the total output. Compare this volume to the chemical manufacturer’s application chart to determine if the travel speed or system pressure needs adjustment.

Essential Maintenance Tips for Off-Season Storage

Proper off-season storage prevents expensive damage from freezing temperatures and chemical corrosion. At the end of the season, flush the entire system with clean water mixed with a dedicated tank cleaner or mild detergent. Run this solution through the pump, boom, hand gun, and return lines to neutralize and remove all chemical residues.

Once clean, drain all water from the system, as even a small amount of trapped water can freeze, expand, and crack the pump housing or boom fittings. Run non-toxic RV antifreeze through the pump until it sprays out of the nozzles, ensuring the entire system is protected. Remove the spray nozzles and screens, clean them with a soft brush, and store them in a dry container to prevent clogging and corrosion.

Store the sprayer unit in a dark, dry shed or barn to protect the plastic tank and rubber hoses from UV degradation. Disconnect the wiring harness from the battery to prevent slow electrical drains or corrosion on the terminals. Inspect all hoses for cracks, dry rot, or soft spots, making a list of replacement parts needed before the next spring arrives.

Setting up a reliable, safe spraying rig on a utility vehicle takes a bit of planning and the right mounting gear. By securing the tank properly, managing the shifting liquid weight, and performing routine maintenance, a part-time farmer can protect both their equipment investment and their land. With the proper tools in place, managing pastures, orchards, and fence lines becomes a straightforward, highly efficient task.
