ProPush Series (HP)

The KUHN Knight HP 150 and 160 hydraulic-push manure spreaders feature the proven ProPush® design customers have come to love. The HP 150 & 160, with VertiSpread® vertical beaters, are designed to haul and spread solid materials from dairies and feedlots, including gutter manure, yard scrapings, bedding pack and feedlot manure. The hydraulic push-type design means no apron chains, fewer moving parts and dependable service life.

The HP 150 and 160 join the HP 140, but feature greater heaped capacities and heavier-duty components. The all-steel welded frame on the HP 150 & 160 provides a solid foundation for the spreaders sides and floor. The solid weld-in tongue is cross-braced for strength and rigidity, while the updated pusher design has increased the clearance between the tractor and implement for greater maneuverability. VertiSpread vertical beaters provide customers with a uniform 25-30 foot spread pattern with excellent material breakup. Poly floor and sides minimize friction and deliver exceptional machine cleanout. For precise monitoring and application tracking, an optional scale system is available.

Your benefits

Durable Construction for Long Life


All-Steel Welded Construction

The all-steel welded ProPush® construction provides a solid framework and includes a reinforced tongue that pulls directly from the full-width axle. This results in a stronger, more dependable spreader since the unit is pulled from the axle rather than the front of the box.

Solid Weld-In Tongue

A solid weld-in tongue provides structure and is an anchor for the pusher cylinder. The tongue is crossbraced for strength and rigidity. Design enhancements allows for more clearance between the tractor quick hitch and implement, improving maneuverability.

Integrated Welded I-Beam Construction

An integrated welded I-beam construction ties the box together while providing a strong backbone for the pusher panel as it travels back and forth.

Heavy-Duty Tandem Axle

A rugged, tandem axle allows the unit to travel across a wide range of terrain with ease. A 10-bolt bogie system utilizes a simpler design with fewer moving parts compared to a sprung undercarriage, which reduces maintenance requirements and increases dependability. Improved axle pod design features a one-piece axle tube to handle additional weight. Two tire choices are available for the HP 160, truck and high-flotation tires.

Fast, Efficient Unloading


ProPush Design

The ProPush box spreaders are designed with simplicity in mind. The hydraulic push-type design means no apron chains, fewer moving parts, faster unloading and dependable service life.

Piggyback Hydraulic Cylinders

This unique cylinder design provides smooth and uniform travel through the entire stroke and rapid cylinder retraction spreading is completed. The cylinders are completely protected by a structural tube member. This stops manure from falling directly onto the cylinder which helps prevent premature seal failure.

Improved Pusher Design

The redesigned pusher on the HP 160 features a bird beak design that allows for better cleanout of the load. This also allows the mounting point of the cylinders to be moved forward, resulting in better clearance between the tractor and implement as well as the ability to add a CV PTO option.

Friction-Resistant Polylaminate Floor & Sides

A two-piece, ⅝” solid polylaminate floor and single piece, 5/8” polylaminate sides provides more strength and durability than individual tongue and groove boards while reducing friction. This means less power is required for unloading versus steel or wooden floors and sides. The polylaminate floor provides impact resistance when dropping heavy loads into the spreader. The plastic floor and sides also reduces winter freeze-down issues.

Heavy-Duty Vertical Beaters


Wide, Consistent Spread Pattern

VertiSpread vertical beaters provide a wide spread pattern in an array of materials. These beaters are designed to spread material in a 25-30 feet pattern at rates ranging from 5-30 tons per acre. VertiSpread vertical beaters are designed particularly for operations that spread a wide variety of solid materials such as penpack or material heavy with dirt.

The beater module can easily be removed for storage while stockpiling, providing you with greater machine versatility.

Heavy-Duty Beater Module

The HP 160 comes with a heavy-duty vertical beater module, featuring 5/8” (1.6 cm) flighting and hardened beater tips. Power to the beaters is routed through a fully enclosed Berma gearbox, providing a strong and reliable power supply with low maintenance requirements.

Beater Drive - PTO Options

Power from the tractor to the unit is transferred through a center-mounted driveline that operates at 1,000 RPM PTO and either 1 3/8” or 1 3/4” to easily adapt to the customer’s tractor. This is accompanied by an option of CV or Non-CV PTO. The CV PTO option is designed for operators that spread at low rates or operators who wish to continue spreading into headland turns.
