We call our fertilizer tank trailers Krop King for a reason. When fertilizer needs to move, your trailer has a job to do. Stainless steel construction, practical hookup access, and thoughtfully selected equipment give that name something to stand on.
At Kraft Tank, we pay attention to the details you will work with every day, from where you connect a hose to how you access the pump. Our fertilizer lineup starts with a well-equipped standard package. Krop King Platinum and Diamond editions take if further, giving you more ways to put the right equipment to work.
A Strong Start Comes Standard
The fertilizer tank trailers featured in our line upstart with a T304 stainless steel tank and a 5,600 gallon capacity. Two baffles, air ride suspension with stainless steel axle hangers, and eight aluminum wheels are part of the standard package.
The working details receive attention, too. A 12-inch stainless steel hose tray provides dedicated hose storage, while a six-lug manlid and two 3-inch cleanouts provide tank access. Extended outlets on both sides and a forward tee for pump access round out a package built with daily use in mind.
Shallow-drop, deep drop and multi-compartment options give you additional configurations to discuss with our team. We can help you narrow down the setup that fits your hauling and delivery needs
Hook up and Get to Work
Every delivery location has its own layout. Access to your trailer should give you flexibility when it is time to connect.
Kraft’s standard fertilizer units include extended street-side and curb-side outlet access, giving you connection points on either side of the trailer. A forward tee provides access for pump installation. These details can help reduce unnecessary repositioning when setting up to load or unload.
Platinum puts more in your corner
Some upgrades earn their place in the daily routine. The Krop King Platinum Edition brings them together in one package, with added features for the running gear, storage, and exterior. It is a step up for operators who want more of their equipment wish list included from the start. The Platinum package includes: Disc brakes in place of standard, a stainless steel rear toolbox, automatic front lift axle, removeable front fender brackets, four tail light boxes, and automatic tire inflation.
The rear toolbox adds a dedicated place for tools and smaller essentials, while automatic tire inflation brings an additional tire-management feature to the package. Paired with disc brakes and an automatic front lift axle, these upgrades make Platinum a well-equipped option for customers who want to step up from the standard configuration.
Diamond Brings the Finishing Touch
A hard-working trailer can look the part, too. The Krop King Diamond Edition carries forward the Platinum upgrades, then adds side LED lighting and a rear Ring of Fire LED lighting package for a strong finish.
Our featured Diamond unit pairs a 5,600 gallon T304 stainless steel tank with a 30-inch deep-drop design and T316 stainless steel framing, including the axle hangers. Its equipment details include an integrated rear tool-box, and automated lift axle with manual override, and a forward tee in the discharge piping for pump installation.
Yellow marker lights along the exterior rings on both sides and the read rear lighting ring gives this unit its signature look. The result is a fertilizer trailer with attention to both its working features and its finished appearance.
Pump Options for Your Fertilizer Tank Trailer
The trailer is only part of the setup. Pump placement, outlet location, and service access matter when configuring equipment for your delivery routine. Kraft offers packaged pump options and can work with you on a custom configuration.

Pump option #1 – includes street-side and curb-side pump outlets, standard couplers for quick hookup, and an enclosed stainless steel cabinet to protect the pump and engine.

Pump option #2 – with a curb-side outlet and an exposes mounting bracket, this configuration provides straightforward access for service, and a low profile.
