A world-class chemical handling system for both ground and aerial sprayers:


One of the biggest headaches in agricultural spraying is getting your crop protection products safely loaded, mixed and transported to the sprayer in as little time as possible, with safety in mind and contact with the product minimized.  The Handler accomplished this.

The Handler is a proprietary line of chemical handling systems that enables quick, easy and safe mixing and loading of agricultural chemicals into sprayers, airplanes and hauling tank systems.  Originally developed by a Canadian farmer who was tired of having to climb up onto his sprayer to dump 2 1/2 gallon jugs of chemical, only to have to fight with rinsing them, the Handler has evolved into a total crop protection management system.

Available in 4 sizes and proven in tens of thousands of farms from across the world, The Handler reduces the time that it takes to properly load and mix a sprayer.  The key to a successful spraying operation is spending less time loading and more time spraying, without sacrificing safety.  With the Handler safety, speed and effectiveness are combined into a single unit that will quickly become the lifeblood of your spraying operation.

Each model comes with a wide variety of features designed to ease the loading process:

  • Available in four (4) convenient sizes – 15, 42, 70 & 230 US gallons
  • Handles liquid, dry and bulk product
  • Built-in bulk handling capability
  • Fill your sprayer fast, safely and effectively
  • Patented knife system to maximize mixing speed and minimize waste
  • Ensures safe disposal of chemicals and minimizes exposure.
  • Fresh water rinse line for equipment cleanup and line rinsing
  • Weatherproof, UV resistant black hose throughout
  • Dedicated, venturi powered bulk suction line
  • Exclusive double venturi for easy emptying of bulk containers
  • 3” seamless Handler bypass offers the highest volume bypass flow yet!

The Handler is available from retailers and distributors across North America, Europe and Australia.

The Handler became the top selling specialty loading system in North America because of its ability to cut, empty and rinse a container in seconds.   As spraying has changed, so has The Handler.  In addition to The Handler knife, the system also mixes powders and dry products easily and quickly, draws from bulk containers using the Handler venturi on select models, and utilizes cone-bottom, calibrated tanks to easily accommodate batch mixtures and bulk chemical metering.

The Handler is such a great investment for spraying operations; you’ll wonder why you didn’t buy one before!

The Handler comes complete with:

  • 2 or 3 inch camlocks for easy hook -up
  • a proprietary, high-performance glass-filled polypropylene venturi fitting, to empty your Handler in seconds using only the water flow from virtually any transfer pump (Handler I, II & III)
  • bulk adapter connections to draw directly from bulk containers without the need for a slow, unreliable chemical pump (Handler II & III)
  • a high-visibility, calibrated, cone-bottom tank that works on any terrain
  • optional frames that accommodate any 2 or 3 inch transfer pump (Handler II, III & IV)
  • optional recirculation packages to allow for batch mixing (Handler II, III & IV)

Double Venturi Bulk Handling Capability Flow Meter Kits

1Increased speed and the reduction of the bottlenecks normally associated with loading a sprayer are the keys to spending less time loading the sprayer and more time using it.  The new Handler Exclusive double venturi allows for easy and seamless suction between the Handler tank and an outside bulk container.

2Each Handler II and III is now Bulk Ready allowing you to cut out low volume 12 volt pumps and utilize the proven speed of the Handler venturi to move chemical faster than ever.

3Draw from bulk containers using your Handler II or III.  By adding a 1” or 2” Banjo magnetic flow meter or a 1” GPI flow meter, and a bulk adapter kit you use the Handler venturi to directly induct product into the fill line.  This non-mechanical process eliminates the need for slow chemical pumps and simply won’t break down.

RotaCraft Tank Rinse Nozzle Banjo Manifold Fittings Optional Pump Kits

4The RotaCraft comes standard with every Handler III and Handler IV.  This high capacity tank rinse nozzle prevents cross contamination, and quickly and easily rinses out the tank.

5A plumbing system featuring the innovative Banjo manifold threadless fittings is available with every Handler model.  With the manifold system, assembly time is shorter, leaks are eliminated, and parts are easier to repair or replace.

6A pump kit is optional with the Handler II, III, and IV.  The kit comes complete with a recirculation package (making it easy to batch mix virtually any chemical); a pump frame (Handler II and III only); all of the assembly hardware; and a versatile Honda-powered Banjo polypropylene pump.

The Secret of the Patented Knife

What is the secret? The Handler uses a patented knife system to

  1. cut plastic chemical jugs,
  2. empty their contents for mixing, and
  3. fully rinse the jugs for safe disposal

All in less than 30 seconds while filling your sprayer!  There is no waste – your chemical is fully used.  (Industry tests show without proper rinsing an average of 2 ounces of chemical remains per container and is wasted!).  Working in conjunction with a custom-made Handler venturi, the Handler can save you time and money and decrease your risk of exposure to potentially harmful chemicals.  How it works:

The pump is running and the user grabs a full, unopened container of product.  With The Handler there is no need to waste time opening the lid and peeling the foil seal.

The user punctures the jug bottom with the patented knife, and the product flows from the container into the calibrated Handler tank.  Depending on the system configuration product remains in The Handler tank or flows directly into the venturi toward the sprayer.

The jug has emptied and user begins to rinse the container with fresh water.  The high volume, high pressure rinse removes all remaining product from the container and effortlessly achieves the trip rinse required by many disposal sites.

The container is completely rinsed with fresh water and no product remains.  The jug has been rendered useless and is ready for safe disposal.
