If you need a 300-gallon sprayer, the FIMCO 300-gallon model is the closest match, but it is a three-point tractor sprayer—not a trailer sprayer. For tow-behind use, the NorthStar 55-gallon model offers the largest listed trailer capacity, while the 31-gallon NorthStar and 25-gallon Master Manufacturing models suit smaller properties. The Tarden is a handheld garden sprayer, not a substitute for a large-capacity rig.
| Product | Best For | Capacity | Mounting or Style |
|---|---|---|---|
| FIMCO 300-Gallon Sprayer | Large-volume tractor spraying | 300 gallons | Three-point, PTO-powered |
| NorthStar 55-Gallon Sprayer | Higher-capacity towing | 55 gallons | Tow-behind |
| NorthStar 31-Gallon Sprayer | Wide boom coverage | 31 gallons | Tow-behind cart |
| Master Manufacturing 25-Gallon Sprayer | Small lawns and spot treatment | 25 gallons | Pull-behind |
| Tarden Battery Garden Sprayer | Small garden tasks | 1.8 gallons | Handheld |
FIMCO 300-Gallon Three-Point Tractor Sprayer
Best for: Buyers who need the listed 300-gallon capacity and have a compatible tractor setup. This is the only supplied product with a 300-gallon tank, so it is the closest match for large-volume spraying.
Its UV-resistant polymer tank has an 8-inch lid and a drainable design for filling and cleanout. A PTO-powered HYPRO cast-iron eight-roller pump delivers up to 22.5 GPM and up to 300 PSI. The 22-inch spray wand is described as reaching up to 45 feet horizontally and 30 feet vertically, with adjustable patterns.
Important limitation: This is a three-point tractor sprayer, not a trailer sprayer. It uses PTO power, so choose it only if that mounting and power arrangement suits your equipment.
NorthStar 55-Gallon Tow-Behind Sprayer
Best for: Buyers who specifically want a tow-behind unit and can work with a capacity below 300 gallons. Among the listed tow-behind models, its 55-gallon tank is the largest.
The sprayer has a four-roller pump rated at 7 GPM, adjustable pressure up to 150 PSI, and a 160cc Honda GX160 engine. Clear PVC hose helps users monitor chemical flow, and left and right boom shutoff valves allow control of each side.
Important limitation: Its 55-gallon capacity is far below 300 gallons. Choose this if tow-behind operation matters more than matching the requested tank size.
NorthStar 31-Gallon Boom and Spot Sprayer
Best for: Property owners who want a tow-behind cart with both boom and spot-spraying options. Its boom has a listed 120-inch overall width and 80-inch effective spray width, with independent left and right nozzle controls.
The 31-gallon UV-resistant tank has molded gallon markers and a 7.5-inch lid. A 2.2 GPM, 70 PSI, 12-volt pump is described as continuous-duty. The spring-loaded breakaway boom arms fold for storage and are designed to absorb impacts.
Important limitation: Its tank is much smaller than 300 gallons. The 12-inch pneumatic wheels and cart make it a trailer-style option, but do not provide the capacity of a large agricultural sprayer.
Master Manufacturing 25-Gallon Pull-Behind Sprayer
Best for: Lawn owners looking for a smaller pull-behind unit with broadcast and spot-spraying functions. Dual deflector nozzles provide adjustable broadcast coverage up to 7 feet, while the spray gun reaches up to 25 feet vertically and 30 feet horizontally.
It includes a 2.2 GPM 12-volt Everflo diaphragm pump and a pressure-regulating system. The adjustable spray gun offers an alternative to using the broadcast nozzles for targeted applications.
Important limitation: The 25-gallon tank is intended for smaller-scale work than a 300-gallon setup. Avoid it if minimizing refills or treating extensive acreage is the priority.
Tarden 1.8-Gallon Battery Garden Sprayer
Best for: Gardeners who need a portable sprayer for plants, beds, and small spot-treatment jobs—not buyers seeking a trailer or 300-gallon sprayer.
This 1.8-gallon model has a rechargeable electric handle, two power modes, an LED battery display, and a listed operating time of up to three hours per charge. Three nozzle heads create five spray patterns, and the stainless-steel wand adjusts from approximately 12 to 35.6 inches.
Important limitation: Its handheld format and small capacity make it unsuitable for trailer-scale coverage. Select it only when portability and garden-level tasks are the priority.
Buying Guide: How to Choose a 300-Gallon Sprayer
Do you need a trailer sprayer or a 300-gallon tank?
These requirements point to different products in this list. The FIMCO meets the 300-gallon capacity target but is a three-point, PTO-powered tractor sprayer. The NorthStar 55-gallon model is the largest listed tow-behind option, but it does not come close to 300 gallons. Confirm which requirement is essential before choosing.
What pump and power source fit your equipment?
The listed products use different systems. FIMCO uses PTO power and a high-flow pump; the NorthStar 55-gallon model has a 160cc gasoline engine; the 31-gallon and 25-gallon models use 12-volt pumps. Match the power source to the tractor, towing equipment, and operating setup you have. The product details do not establish that every model will work with every vehicle.
How much coverage control do you need?
For boom coverage, compare spray width and nozzle controls. The NorthStar 31-gallon model lists an 80-inch effective spray width and independent left-right control. The Master Manufacturing model lists up to 7 feet of adjustable broadcast coverage and includes a spray gun for targeted work. The FIMCO lists an adjustable-pattern wand and reach figures rather than a boom width.
What tank features matter during filling and cleanout?
Large tanks need practical access for filling and draining. The FIMCO lists an 8-inch lid and drainable design. The NorthStar 31-gallon tank has a 7.5-inch lid and molded gallon markers. Compare these details with your mixing, rinsing, storage, and transport routine, and follow the chemical label and sprayer instructions.
