For UTVs and Compact Tractors

The 300 gallon compact Kiser Water Wagon hauls and applies large volumes of water around the farm or property. This compact trailer, built on a low riding proprietary frame, is ideally suited for smaller tow vehicles such as UTVs and compact tractors. It is powered by an engine and pump to apply variable amounts of water from either the rear spray nozzle(s) (wide spray) or the available spray hose (spot application). Additionally, it has the ability to turn the flow of water on and off, on-the-fly, from the seat of the tow vehicle. Common uses include dust abatement, irrigation, hydration, watering, washing, and supplying in applications such as horse arenas, general property, nurseries, ballfields, pools, parks, farms, and more! The Kiser Water Trailer comes loaded with features perfectly selected to make this an invaluable and versatile trailer for your water application needs. Not for use on public roadways.

Designed For ATVs, UTVs & Compact Tractors

Designed For Use With Some ATVs, UTVs & Compact Tractors:

Over the past few years the ATV / UTV market has seen tremendous growth. Many horse arena owners and property owners are now using ATVs and UTVs instead of, or as a supplement to, a tractor. This causes a problem when it comes to water wagons as most wagons are simply too large and heavy for an ATV or UTV to operate. To meet this growing need for water wagons, that may be used with some ATVs or UTVs, ABI has designed the 300 and 500 gallon Kiser water wagons.
Brass Spray Nozzle

Brass Spray Nozzle:

The brass spray nozzle produces a spray pattern that covers a swath from 6' to 20' wide. The spray pattern is a flat 110° fan (at 40 psi). Increasing the motor speed will increase the pressure and therefore the spray width as the water will be projected further, out the back, before landing on the ground. Water is distributed evenly to eliminate inconsistent application of water that can create a dangerous "wet" base material. Even application of water is essential to consistent arena footing.
On/Off Flow Control: (From Seat Of ATV or Tractor!)

On/Off Flow Control: (From Seat Of ATV or Tractor!)

The ratcheting valve and attached rope enable the operator to turn the flow of water on and off without leaving the seat of the tow vehicle. Ideal for shutting off water flow when traveling over areas that have already been watered or do not need to be watered. This conserves water and eliminates over or inconsistent watering that can be detrimental in certain applications. In a horse arena this feature is a necessity! Rope is included.
"Banjo" Brand Plumbing:

"Banjo" Brand Plumbing:

The plumbing system is designed with simplicity in mind. The valves are top quality "Banjo" brand name so you can rest assured the plumbing system will provide long service life. The pipes and fittings are galvanized steel and the hoses are non collapsible and corrugated. When the wagon is loaded with the optional spray hose and optional quick fill system the wagon has 4 total 1.5" valves.
  1. Spray Nozzle Ratchet Valve - Located at the top of the system this valves turns the back spray nozzle on and off.
  2. Spray Hose Valve - When installed this valve turns on and off the spray hose.
  3. Quick Fill Valve - When the optional quick fill hose is attached this valve directs the pump to either draw water out of the tank or out of the external water source.
  4. Pressure Release/Circulate Valve - This valve directs water back into the tank. This can be used to assist in adjustment of the water pressure in the system. For example: Close this valve for maximum pressure and maximum spray distance. Open this valve fully to cycle water back into the tank. Or partially open or close this valve at varying intervals to either increase or decrease pressure in the system.
Powerful Motor

Powerful Briggs & Stratton Engine:

The Briggs & Stratton 550 Series engine utilizes Overhead Valve (OHV) technology. It features an automotive-style air filter, cast iron cylinder sleeve, and dual ball bearings for longer life. With 5.50 Torque (ft-lbs, gross) and 127cc engine displacement this engine creates a significant amount of power. The Overhead Valve Design (OHV) runs cooler and cleaner delivering more power, smoother operation, longer engine life, and improved fuel economy. The Dura-Lube Splash Lubrication System is a gear driven system that continuously supplies oil to all internal parts. The gas fuel tank is 2.0 Quart for long run time and the oil capacity is 20 oz.. The pump is separated from the engine by a 1/2" and a special slinger/engine seal protects from any corrosive fluids.
Poly "Banjo" Pump

Powerful Poly "Banjo" Pump:

The pump is a high quality and long lasting Banjo brand pump. Banjo is the industry lead in pumps and valves. This is a corrosive resistant 1.5" polypropylene self-priming centrifugal pump. Priming is now made easier by the incorporation of two new prime and drain plugs for quick priming and draining before and after use. The pump and engine are separated from each other by a 1/2" and a special slinger/engine seal protects the engine from any corrosive fluids.
Polyethylene Eliptical Tank:

Polyethylene Elliptical Tank (300 Gallons):

The 300 gallon tanks are easy to drain and wash out (if needed) after use due to the unique full drain elliptical design. These tanks are rotationally molded for superior quality and are FDA approved for potable water usage. The elliptical tank is designed to keep the water as near to the frame as possible to minimize the risk of becoming top heavy. The white tank allows the user to see the fill line (in day light) and has measurements on the front and side in both gallons and liters. The tanks are equipped with an 8' vented lid for easy top filling and cleaning. The tank is secured to the frame and saddle with a metal band.
All Welded Steel Frame & Custom Tank Saddle:

All Welded Steel Frame & Custom Tank Saddle:

The frame is fully welded tube steel and is custom engineered for the demands of the enormous weight of water. This is not a stock trailer frame. This frame features extreme durability and long service life. No bolts here! The steel saddle that mounts to the frame and secures the water tank is also custom designed. Only the highest quality steel, superior craftsmanship and powder coating is acceptable.
Adjustable Hitch System: (Ideal For ATV / UTV)

Adjustable Hitch System: (Ideal For ATV / UTV)

Quickly & easily connect to most any town vehicle with the adjustable hitch system. The hitch adjusts to properly line up the tongue of the wagon to a variety of hitch heights for ease of use with different size ATVs, UTVs and tractors. A 2,000 lbs. swivel crank jack is included to easily raise or lower the hitch to meet up with the hitch of the tow vehicle. A pin hitch is standard and ideal for farm and ranch use.

"For years I neglected the amount of water I put in my arenas and my footing was always slick and dangerous. I had different watering systems, but nothing was easy to use or did a good job. That is until I bought my Kiser Water Wagon! My water wagon was built to fit my needs and it doesn't tear up my arena like my old water truck. Not only that, it lays out the water so evenly that my footing is exactly the same in every part of my arena! Don't even hesitate if your looking for a new watering system, buy the Kiser Water Wagon now! It's the easiest and most cost effective way I found to keeping my footing moist!" - Clinton From Texas
"My wife asked me why we had waited for years to purchase this water wagon. I am sure we will get some good use out of the unit before winter. Thanks to ABI for the pointers and advise. My phone call with customer service was well worth my time. I am surprised by the high quality of the product, both the design and manufacturing. As was said in one of the videos on your website "Attention to Details". I have worked in the government aerospace industry and could only wish for such high quality products." - Tom From Massachusetts
