Rock King

Degelman introduces its largest rock picker ever. With an incredible 8’ wide grate, 5 cubic yard bucket and 7’3” dump height, the Degelman Rock King is simply second to none.

The King is Here.

The Degelman Rock King is the culmination of more than 55 years of pursuing excellence. Degelman rock pickers are unrivaled for performance and durability and are THE industry standard. Our attention to detail means these machines will work flawlessly for years to come, as you will commonly find Degelman rock pickers made 55 years ago still working today.

Zero Maintenance Technology

The Rock King design is over-built with zero maintenance technology. Here you will find the latest in sealed bearings and oversized machined shafts and pins with maintenance free composite bushings and commercial grade quality.

Pin Eye Cylinders

The Lion WP 3000 welded cylinder series is designed to withstand the most demanding applications on the market today. Lion’s extensive design experience has resulted in a premium cylinder with the latest in sealing technology. Standard Lion 1000 induction hardened rods provide the ultimate in corrosion protection and durability.

Bushing Seal

The wiper edge removes even the toughest dirt and contaminants from the pin, keeping the system running clean and at its peak performance. The metal enclosure ensures a secure fit in the open housing, preventing expulsion of the wiper, even under extreme conditions.

Round Solid Steel Grill

The grill teeth on the Rock King are made of round solid C1045 steel shafts. This steel is much stronger than ordinary mild steel and has a natural spring to it to resist impact damage. A Degelman grill is extra heavy, developed with the optimum sweeps and curves to separate rocks from stones. Every third tooth is welded to the frame to allow small lodged rocks to clear freely. The round profile itself is also the optimum shape with the smallest choke point to minimize jams.

Precision Grill Control

The wheel placement created between the tractor hitch and the offset tires provides precise reactive control over grill depth, exceptionally important when working in soft and/or wet field conditions.

Frame Design

Rock pickers are used in the most abusive and harsh conditions known in the agricultural and construction markets. Hitting, lifting and picking hard heavy stones puts enormous stress on equipment. A durable rectangular frame design is the heart of a Degelman rock picker. It supports these big loads and carries the weight of the grill and reel assembly. Even the inside corners are supported by heavy angle plates that tie the frame tubes together.

Advanced Reel Spring Design

The reel spring assembly moves constantly under heavy loads and is designed to arc back under pressure and release. The spring is a heavy-duty compression design exclusive to Degelman, which has taken years to perfect. It works better and lasts longer than typical extension springs. Paired with this is a urethane puck that dampens vibration and minimizes backlash as the reel paddle decompresses. Finally, a simple bend integrated into the spring holder plate greatly increases the strength of the spring holder.

Heavy Reel

The oversized reel plates are heavy and designed to withstand abuse. The reel side plates are laminated and incorporate formed edges that dramatically increase the reel’s strength and providing a natural deflective surface. Small details can make a big difference.

Superior Rock and Soil Separation

Degelman rock pickers are designed to pick stones quickly, efficiently and with a minimum of soil collection. The geometry between the reel and grill is designed so that the paddle makes the first contact, lifts and spins the stone onto the grill further separating the rock from the soil.

The unique interlaced grill and paddle teeth drop dirt easily onto the field. Even the bottom and rear of the hopper box make use of grated spring bar strapping to keep rocks in and dirt out.

Extra Plates, Extra Welds, Extra Strong

Backing into a rock pile with a weighted rock picker can damage key components. The hydraulic hose cover is welded to the box frame to be even stronger in a key crush point. The back of the hopper box is constructed of double walled formed steel as it receives heavy pounding by rocks in the hopper and the area most likely to become damaged.

Where crush damage and daily wear are more likely, areas have been reinforced to ensure years of trouble free operation. For example, the grill side plates have additional reinforcement plates added to counter head-on damage.

Removable Tire Assemblies

Distributing weight and minimizing the pounds per square foot in soft wet conditions is necessary. These large diameter tires disperse the weight of rocks in the hopper and reduce the possibility of heavy rutting on your valuable fields.

We make changing the tire, rim or spindle a much simpler process by providing a single bolt through the spindle. Changing the running gear is quick and painless.

Increased Ground Protection

Degelman Rock King uses Alliance 710/50 R26.5 agricultural tires, offering an extremely wide footprint and rounded shoulders for maximum flotation in any soil condition, minimizing rutting and soil damage. The Alliance tire design helps reduce the power required to pull, resulting in increased productivity and fuel savings.
