2026 UNVERFERTH 3955XL

3955XL – SEED RUNNER BULK TANK TENDER When Unverferth introduced the first self-filling Seed Runner bulk tender, it revolutionized the bulk seed handling industry with its patented design, pivoting the conveyor 180° for easy self-filling from ground level. The 55-Series of this patented product continues the tradition and is sure to bring your operation to a new level of efficiency. A new, low-profile tank design with a large top opening, patented 5-ply rubber conveyor belt design, and Smooth-Start conveyor engagement just to name a few. The all-new 55-Series Seed Runner tender is Innovation…Refined. CONVEYOR PATENTED SELF-FILLING DESIGN The Unverferth Seed Runner seed tender features a patented self-filling design so the conveyor can pivot 180° and be positioned to fill itself easily from the ground level. Every conveyor is equipped with a convenient conveyor arm locking mechanism and spring lift assist for easy handling when pivoting the conveyor. SEED PROTECTION Handling your high-value seed with the greatest care is crucial for any seed tender. At Unverferth, we’ve spent years researching and testing different designs, resulting in the 55-Series conveyor which excels in protecting your high-value seed investment. CONVEYOR TECHNOLOGY • The patented 5-ply rubber conveyor belt features offset rows of cupped cleats to minimize seed damage while providing a greater carrying capacity. The offset in each cleat allows the belt to cup inside the conveyor tube and pass by each other to reduce seed pinching. • The conveyor inlet features patented side seals and a brush-seal-brush design to prevent seed from back feeding into the bottom of the conveyor, minimizing seed damage. • The extended-length rounded conveyor hood is rubber lined for enhanced seed flow and protection. • The top-mounted, 6-cubic-inch hydraulic motor pulls the belt forward, keeping it tight for the most efficient and gentlest seed movement. UNLOADING SPEEDS • For operations that need the fastest unloading speeds, DXL Models feature a 10” (or 8" is also available) conveyor tube, providing unloading speeds up to 45 bushels per minute. • If you’re filling a larger central fill planter or drill, the 8” conveyor tube on XL Models, 3755 and 2755 is a good choice for unloading up to 35 bushels per minute and extra unloading height. • The 6” conveyor tube on models 3755 and 2755 unload at 16 bushels per minute for precise control when filling individual planter or drill boxes. CONVEYOR LENGTH Conveyor length is measured from center of the top bearing to center of the bottom bearing for a true measurement of side reach and unloading height. EASY FILLING • DXL models utilize a 24’ long single-stage conveyor whereas the model 4955DXL features a max unloading height of 16’6” and 90” of hydraulically-operated vertical height adjustment. Model 3955DXL features 15’ of maximum unloading height and 83” of hydraulically operated vertical height adjustment. • XL models utilize a 21’ long conveyor with a maximum unloading height of 13’6” and feature 68” of hydraulically-operated vertical height adjustment. • Models 3755 and 2755 utilize an 18’ long conveyor with a maximum unloading height of 12’ and 54” of hydraulically-operated vertical height adjustment. • All models are standard with two downspouts to fit your operation's needs. The 4’ flex spout is ideal for filling central fill planters or drills while the 2-stage telescoping downspout is ideal for filling individual planter boxes and reach up to 37’ on DXL models, 34’ on XL models, and 30’ on models 3755 and 2755. CONVEYOR CONTROLS Model 4955DXL is standard with a 3-function wireless remote that operates the conveyor on/off, the conveyor raises/lowers and opens/closes the tank doors. All other models are standard with an electric 2-function wired remote that raises/lowers the conveyor and turns the conveyor on/off. All models can be equipped with optional wireless remote packages that can be found in the accessories section. CONVENIENCE FEATURES Every conveyor is equipped with the Smooth-Start engagement feature which gently brings the conveyor belt up to maximum speed, which increases the belt life. Electronic speed control allows the operator to adjust the speed of the conveyor belt independently from the engine for fine-tuning the unloading speed. A tool-free removable belt access cover allows the operator to quickly check the belt tension to ensure proper operation. Cleaning out seed between varieties is quick and easy with the tool-free removable hinged cleanout door located at the bottom of the conveyor. ADDITIONAL FEATURES • The conveyor can be stored in the front or swung 180° to the rear of the seed tender for convenient road transport. Stainless steel rollers and roller plates allow the conveyor to swing from front to rear and locking increments ensures the operator can lock the conveyor every 10” for unloading versatility. • A redesigned over-center hopper lock is easy to use and the large rubber hopper intake at the bottom of the conveyor increases seed flow. • A standard hopper cover has elastic bands that hold it tightly in place to safeguard the contents. SEED HANDLING VERSATILITY All 55-Series Seed Runner seed tenders feature a dual-compartment tank design for handling multiple seed varieties. The graphite coated interior ensures quick and complete cleanout of seed. TANK DESIGN • The 55-Series Seed Runner tank has been purpose built for a low-profile design making it more stable in transport and provides an unobstructed top opening so you can easily fill the seed tender, even in the corners. The unique tank shape allows the conveyor to be raised and swing from side-to-side without contacting the tank. • Upper and lower viewing windows in the tank allow the operator to easily monitor the contents and standard fill light indicators towards the top of the tank alert the operator when the seed is reaching the fill level. • Model 4955DXL features hydraulically operated 10” wide by 15” tall unloading doors and all other models feature 8” wide by 10” tall wheel-operated unloading doors for optimizing seed flow into the conveyor. • The regulating baffle mounted near the unloading doors directs seed into the conveyor intake which increases unloading efficiency. ROLL-TARP The standard 18 oz. roll-over tarp stays tightly locked at highway speeds and protects the tank’s contents from adverse weather conditions. VIEWING LADDER The standard 20” wide non-slip viewing ladder allows the operator to quickly and conveniently check the tank contents.
