The M SERIES Manure Spreader design is unmistakably Degelman. The most rugged, toughest built machines available. 

From the ground up, these spreaders have been designed with rocks in mind, from its proprietary retractable free-swing flails, super duty gearbox, smooth sidewalls and heavy-duty frame to its clean gate opening.

 Rock Bypass System (RBS)

Up until now, all spreaders in the world employ beaters made from some variation of a helical or auger shape. This inherently rigid design is always vulnerable to rock damage and high maintenance costs. The Degelman ROCK BYPASS SYSTEM (RBS), the heart of the M series, is nothing short of revolutionary. Five rows of free-swing flails, not only collapse upon stone impact, but will exceed expectations for throw distance, durability and even distribution pattern.

Degelman manure spreaders cut and tear material, drop heavier crumbled material to the next lower set of paddles for final processing and discharges material over 60 feet.


Hammerhead Paddle Technology

How do you build the best manure spreader in the world? Start with Degelman, renowned for building legendary equipment for the past 50 years. The design is unmistakably Degelman. After five years of design, development, and intensive testing, Degelman introduces the most rugged spreaders available - the Degelman M Series.

From the ground up, these machines have been designed with rocks in mind, from its proprietary retractable free-swing flails, super duty gearbox, smooth sidewalls, and heavy-duty frame - to its clean gate opening.

Hard Chrome Plated Pin

Simply the best corrosion resistance available in a hard chrome plated bar. Stelmi chrome plated bars can be produced with an increasing range of cost effective corrosion resistance (neutral salt spray testing to a 9 minimum rating). Our superior corrosion resistance stems purely from the plating process; Stelmi uses no "waxes" or other coatings that can be used to temporarily enhance corrosion resistance.

Our Premium Double-Lip Seal

Press-fit installation prevents O.D. contamination while the additional sealing lip works in conjunction with Parker rod seals to provide redundant sealing for leakage reduction.

Polygon Composite Bushing

Polygon bearings offer long lasting durability. During extensive testing, both in the laboratory and out in the field, Polygon composite bearings have routinely outperformed metal-backed and metallic bearings, while costing substantially less. Because Polygon composite compoments are inherently noncorrosive, they keep equipment operating efficiently under even the harshest weather conditions.


Forged Tip

USM scientifically developed forged tips are especially compounded from the best wear resistant steel and then heat treated to our specifications. Long wearing tungsten carbide infused hard faced welds are then applied by machine for a uniform placement to specific areas.


Superior Distribution Pattern

Distribution and throw distance is unrivalled with Degelman. Fine pulverized material is spread over 60 feet with secondary field passes normally not required. Hydraulic Push Off systems, however, compress manure as it is unloaded. This compression rate changes as less material is available for offloading resulting in inconsistent field distribution patterns.

Commercial operators have long known that a good chain floor drag system will spread material more evenly and is more reliable. These machines pull the material to the beaters with dual ¾” pre-stretched 100,000+ lb breaking strength marine grade drag chain and the Degelman RBS takes care of the rest.

Optional DIGI STAR Scales

The NT560 Indicator offers record keeping for nutrient land application. 

  • AutoLog - Automatic Start/Stop Function
  • Indicator displays actual tons/acre or lbs/acre
  • View and react to tons/acre or lbs/acre reading by speeding up or slowing down
  • View and change the 26 character alphanumeric data field
  • View and change the 6 character ID
  • Software to create custom reports
  • Calculating the nutrient value of your manure is easy with scales on your spreader

The NT 8000i is a closed-loop rate control system for hydraulically driven, apron floor systems on manure spreaders – providing precision guidance and prescription-based control of spreading rate. 

The unique feature of the NT 8000i is a weight-based, self-calibration and calibration-check system that continuously monitors and readjusts the calibration factor, based on the actual weight of the material spread. The NT 8000i system provides enhanced spreading rate accuracy when working with challenging materials of varying density like manure, litter or compost. 

Optional Four Piston Caliper Brakes

The A, M, H, SCL2 series brake calipers are hydraulically applied; four piston brakes are designed for a variety of dynamic braking requirements. Carlisle premium linings, and flexible mounting alternatives to fit wide range of machinery. Open caliper provides easy access for service.


Fail-Safe Floor Drive

Made in America, our Heavy Duty Marine Grade Chain is made of superior triple alloy steel that provides the best strength-to-weight performance in the industry. This high strength heat treated alloy chain is used to pull the easy to replace 2” x 4” floor slats.


World’s Most Rugged Gearbox

The gearboxes that support the beaters are the largest commercial boxes available. From the inside out, these boxes are overbuilt. The nearly three-inch diameter heat-treated spline shafts are massive. Oil bathed heat-treated gear sets and roller bearings are in some cases twice the size of anything out there. These boxes are designed for years of maintenance free commercial use. The input drivelines also include runaway clutches for further rock protection.


Great Visibility

The front wall, front drive and dosage gate are designed for outstanding visibility from the tractor cab. The front drive is also open for easy viewing and accessible with a single large easy access door for maintenance.

Easy Access Chain Tightener

Over time chains will stretch and the M Series chain tighteners are located on the outside of the machine for easy access and lubrication.


Replaceable Paddles

The paddle cores start with a 1/2" heavy wall mechanical ten inch tube. Impeller paddles are simple and straightforward, produced from 1" Abrasion Resistant 400 material - about eight times more durable than regular mild steel. The paddles are interchangeable, reversible and can be easily replaced by removing a single over sized 1-3/4" stress proof pin - without cutting or welding.


Hollow Rubber Spring Frame Suspension

Degelman manure spreaders were designed to handle heavy manure with a two-fold suspension system to reduce vibration and shock loading to the tractor drawbar and to the machine itself. The first system incorporates low maintenance convolution hollow rubber springs suspended and under slung the A-frame to better distribute loads and to de-amplify shock. Initial take-up is very smooth and the spring rate increase is progressive, resulting in a greatly improved ride, improved load handling and greater load stability.

Walking Beam Suspension

Secondly, Degelman manure spreaders incorporate a straight forward and time tested walking beam floating suspension system. Tandem walking wheels cut uneven terrain in half with a massive unrestricted range of motion. All four wheels are always in contact with the ground surface. Coupled with a wide stance, these machines will ride over the roughest terrain with ease and control.



Optional Goodyear Muck Master Tire

The tire is designed for manure tanks and grain carts, with the wide profile it improved the flotation. Heavy load carrying capacity, and improved design for less mud on the road.


Hydraulic Dosage Gate

The Degelman M Series dosage gate is hydraulically operated to control the flow of material. The inside frame or window is designed to be smooth and clear of potential obstructions for maximum output.

Materials Trailer

The entire drive and beater assembly can be quickly lifted off the machine in minutes to clear any severe blockages and will quickly convert your spreader into a versatile wagon with an active drive floor ideal for transporting other commodities such as dirt and silage.


Top Extensions

Optional top extensions maximize the capacity of your M Series spreader, saving you, even more, time and fuel.
