Degelman Rock Picker - Signature 6000/7200
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.
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.
With the unit in transport position, the picker's solid grill tines can be lowered into the soil to lift partially submerged rocks. While not specifically built for this purpose, the 6000/7200 functions well in the removal of moderately sized stones. For large stone problems, the Degelman Rock Digger is the tool of choice for ridding your field of these oversized rocks.
Operators that clear bush and pasture land
often use Degelman rock rakes to place debris into neat windrows. 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.
From loose dirt and crushed concrete, to
the most abrasive mining applications, Hensley is world renowned for high
quality steel backhoe teeth. This technology is incorporated into Degelman rock
pickers. These cast steel grill tips, provide the ultimate protection against
high impact and high abrasion. The solid grill shafts are precisely milled to
accept these teeth and the tips are easily replaced by removing a simple roll
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 paddle design starts with an
over-sized, heavy wall tube. The teeth themselves overlap the paddle tubes to
protect the tubes from damage. This small detail increases the tube strength,
creates a more robust point of rock contact, prevents tube damage through bowing
and reduces dents. This is but another example of the Degelman difference - no
detail is overlooked.
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.
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. 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
The hitch pole, considerable 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.
PTO or Hydraulic Drive
These signature series rock pickers are
available in both hydraulic drive and PTO drive. The hydraulic motor option is
by far the most popular option as it allows the operator to reverse the reel.
The PTO version, coupled with a heavy-duty gearbox and dry clutch has more
torque and is suitable for picking larger rocks and windrows. Both systems are
available to offer you the best option for your operation.
Another example of Degelman 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.
Unlike most manufactures, Degelman designs and manufactures our own cylinders -
industrial style hydraulic cylinders designed to perfectly match the
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.
Hydraulic hose is normally vulnerable to
rock damage and flying debris and from experience we have protected all key
areas with combinations of removable steel hose guards with flared edges to
reduce cuts, industrial quality hose clamps that reduce vibration
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.
