MENU ROCK RAKE FEATURES SIGNATURE SERIES ROCK PICKER ROCK KING ROCK RAKE ROCK DIGGER PRONG PICKER Used across the globe for over 35 years, the RR1500 has earned a reputation for fast, efficient windrowing in rock-strewn land. Exceptional Quality Used across the globe for over 35 years, the RR1500 has earned a reputation for fast, efficient windrowing in rock-strewn land. Augmented with real-world testing and customer feedback, the original, patented design delivers exceptional quality in a low-maintenance package. Built with durability in mind, robust components like the chain-driven drum and long-lasting bearings raise the bar for performance-driven rock management. The 14' wide spiral drum rakes a large swatch of rocks from the field with each pass, yet the entire machine folds into a 7-1/2' narrow transport width with 10" of ground clearance - ideal for navigating narrow bridges and gates. Windrowing Rock Moving randomly distributed rocks into windrows allows for convenient picking. Capable of forming single or double-windrows, the RR1500 means less passes through the field when removing rocks. Gravel Reclamation Degelman rock rakes are the optimum tool to reclaim gravel from secondary municipal roads. Save money and reclaim up to 75% of lost gravel by pulling the material from the shoulder, breaking and sifting lumps, then depositing gravel back on the road where it belongs. Soil Conditions Level project sites, clear debris, and incorporate soil or fertilizer. Break up clods to prepare a seedbed, and follow with a roller for perfectly planted fields. The RR1500 excels in all of these tasks, and has even been used in diverse operations such as golf course creation, highway construction, and pasture development. Rock-Solid Drivelines PTO units are equipped with heavy-duty Weasler Engineering 35-series Extended Lube Needle Bearing drivelines. Featuring telescoping shafts for effortless coupling, splined gearbox inputs, and a 9000 in-lb dry clutch, PTO rock rakes deliver uncompromising power for serious rock removal. A 900-series Prairie Gear right-angle gearbox completes the PTO-drive system. A solid iron-alloy case houses robust components including tapered roller bearings, high-strength alloy shafts, and oversized Coniflex bevel gears. Optional Hydraulic Motor Hydraulic-drive rock rakes are the choice for tasks demanding quick setup/disconnect and applications that require reversing the drum rotation. The heart of Parker's TK-series powertrain, the torque link, is an extra-heavy-duty part that includes patented 60:40 spline geometry. Rugged construction throughout allows the transmission of over 23,000 lb-in of torque. The entire powertrain is continually washed in cool, high flow fluid to assure long life. Roller vanes and sealed commutator maintain high efficiency and provide smooth low speed performance. Chain Drive with Oil Bath Experienced operators know that a slack chain under load is prone to failure. The RR1500 incorporates a custom threaded tension system for precise adjustment. With a zero-backlash drive chain, stopping to replace a broken chain is no longer a concern. Power is transferred to the field via the tough #100 roller chain system with a safe working load of over 5000 lbs. A weather-sealed chain drive enclosure makes certain that the roller chain and sprockets are protected from damage, while remaining free from abrasive dirt and rust-causing moisture. To keep it all running smoothly, the chain is supplied with constant lubrication from a continuous oil bath system. Automated Ground Contouring A three-spring suspension system stabilizes the rock rake drum over variable terrain. This completely isolates the frame and driveline components from shock loading encountered when striking buried rocks and other obstructions. Drum height and spring contact pressure are hydraulically controlled and can be adjusted during raking operation to compensate for different situations in the field. The tension springs are made of 12 gauge wire capable of absorbing 220 pounds per inch of deflection. Ample spring travel allows the RR1500 to keep moving over large obstacles in the field. Adapt to changing conditions using the standard hydraulically-operated drum angle adjustment. Through a range of 10 to 30 degrees, the drum angle can be tuned for different tasks - from aggressive raking to more complete soil engagement for levelling. Offset the wheel height on each side of the rake to change the contact angle between the drum and the ground - known as feathering the drum - which is essential for breaking up clumps of soil and ensuring dirt-free windrows. Achieve a perfect offset using the bolted wheel brackets for problem-free adjustment. High-Quality Cast Bearings Cast housings hold greasable NTN bearings manufactured with precise tolerances and load ratings higher than the industry standard. Mounted to an oversized shaft, these bearings guarantee smooth operation of the drum even after repeated impact with large rocks in the field. Heavy Shielding Two-ply rubber belting shields are used to protect driveline components as well as ensure rocks remain neatly contained within the windrow. Custom steel guards protect the gearbox and drum bearings from damage caused by pitched rocks and buried obstructions. Reversible, Replaceable, High-Wear Teeth Increased carbon content means rake teeth are less prone to damage, and a robotic hard-surface treatment results in impressive wear resistance. Individual teeth are easy to replace and can even be reversed to effectively double their lifespan before requiring replacement.
