The Degelman Signature series rock pickers are the result of over 55 years of pursuing excellence Degelman rock pickers are unrivalled for performance and durability and are THE industry standard. Our attention to details 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.
The hitch pole, considerably longer than typical rock pickers, is allowed to pivot, providing a large working envelope, superb visibility for picking rocks and the ability to tuck the picker behind the tractor for narrow transport. By simply pulling a pin, the machine is readied for field or transport. For more demanding operators, a hydraulic option is available and recommended for overall ease of use and extremely handy to precisely back up to rock piles.
With a massive 28 inches of clearance between the paddle assembly and the grill, large stones are easily picked. These machines are designed to provide relentless heavy stone work day in and day out.
Operators that clear bush and pasture land often use Degelman rock rakes to place debris into neat windrows. Our Degelman rock pickers were designed to take the normally tough demands of a rock windrows. These windrows are often contaminated with sticks, stumps, crop residue and stones of various sizes and shapes. Degelman Signature series pickers are designed to work tirelessly for this exact purpose.
The grill teeth on the Signature Rock Pickers 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.
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.
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 put 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.
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. Through years of exhaustive research, development and testing, we have found that the soft steel of our cotter pins outlast all other forms of fasteners. Small details can make a big difference.
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, that 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.
Another example of design elegance and simplicity is the utilization of a single set of cylinders which means there is less potential problems to occur. As an operator, you control both the grill height and the dumping of a load of rocks with a single set of hydraulics.
Distributing weight and minimizing the pounds per square foot in soft wet conditions is necessary. These large diameter 16.5L 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.
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.
In locations where crush damage and daily wear are more likely, we have reinforced these areas to ensure you have years of trouble free operation. For example, the grill side plates have additional reinforcement plates added to counter head-on damage.
