The PF 100 Series delivery boxes use a simple, effective twin-auger design for quick, consistent discharge. Similar to the famous twin-auger design of the KUHN Knight ProTwin® Slinger® manure spreaders, the raised right auger of the PF delivery boxes eliminates material bridging and works to consistently charge the lower auger on the discharge side. Proven high performance in a variety of manure materials remains true when unloading a variety of feed ingredients and rations.

The PF 100 Series delivery boxes are available with two auger options; the standard and grain auger configurations. Standard augers are designed with an open convergence area near the discharge door resulting in optimal load leveling and feedout performance in higher roughage, dairy rations. Grain augers feature a closed convergence area near the discharge door, optimized for feeding typical finishing rations.

Close auger-to-floor tolerances allow for excellent cleanout of the delivery box. Another advantage of the auger delivery box design is the elimination of feed carryaround. Unlike other designs that utilize chain conveyors to move feed, augers do not carry feed around and deposit it in an undesired location.

With far fewer wear components than other delivery box designs, auger delivery boxes provide superior component lifetime and require minimal daily maintenance. No chains to replace, less daily service points, and the reduction of a cross conveyor are all examples of how the auger delivery box highlights simplicity and longevity over other designs.

The PF delivery boxes offer many proven heavy-duty components. A 40:1 planetary gearbox is used for speed reduction into the rear of the unit. A splined cast plug is used for the driveshaft-to-sprocket connection. Simple, reliable sleeve bearings are used to maintain shaft alignment. A bolted flange connection is used to mate the drive with the augers.

A variable displacement hydraulic motor reduces unloading times. The motor is capable of making incremental displacement adjustments based on requested feedout speed from the closed-loop software. Through this incremental speed adjustment, the PF delivery boxes can respond to unload speed requests earlier in the unload process, resulting in 50% faster unloading speeds compared to the previous model.

New KUHN truck mount controls provide an operator-friendly experience for delivery box control. On-board machine parameters and diagnostics are accessible on the machine display in order to quickly identify potential issues and monitor the system. An external fuse box provides easy access to fuses and relays. Auxiliary power capability is available in the new wiring harness, an easy power source for scale indicators.

Center-rotating augers bring the feed to the center of the discharge to increase overall capacity and provide a smooth, even discharge for all ration types. The 4-auger discharge comes with power tip-off and built-in magnets. Long-lasting, replaceable polyethylene chute liners prevent rust and limit wear.

The discharge augers are simple to remove for easy serviceability. Long-lasting, replaceable polyethylene chute liners prevent rust and limit wear.

As with the main auger drive, the discharge auger shafts are splined for a more positive power transfer and longer service life. The simplified drive design, featuring only two chains and a remote grease bank, results in easy service and maintenance.
