HP 170 M

The new KUHN Knight HP 170 M, 700 ft³ (19.8 m³) hydraulic push box spreader features the proven ProPush® design customers have come to love, now with the addition of a moving floor and increased capacity. The HP 170 M commercial box spreader, with VertiSpread® vertical beaters, is 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 all-steel welded frame on the HP 170 M provides a solid foundation for the spreader's sides and floor. The solid weld-in tongue is crossbraced for strength and rigidity, while the moving floor has allowed for increased capacity while remaining compact. 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. The HP 170 M has two tire arrangements available depending on customer preference: the 750/45R x 26.5, a radial option, and the 600/55 x 26.5, a bias tire option.

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.

Moving Floor

New to the ProPush family is the moving floor. The moving floor design works in unison with the pusher to unload at a constant rate. The moving floor allows the HP 170 M to increase capacity without sacrificing overall length or loading height.

Piggyback Hydraulic Cylinders

This unique cylinder design provides smooth and uniform travel through the entire stroke and rapid cylinder retraction when 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.

Friction-Resistant Polylaminate Floor & Sides"

A two-piece, 3/4" solid poly floor and single-piece, 5/8” polylaminate sides provide 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 white poly floor reflects UV rays for increased product life while being exposed to the elements. The multi-piece poly floor design allows for expansion or contraction with changing temperatures, while also reducing winter freeze-down issues, a common problem associated with a steel floor. The floor and side panels additionally are backed by a 10-year breakage warranty.

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 170 M 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.
