Rakes are often a decisive link in the forage harvesting chain as we look at planning and workflow. This counts even more for contractors and large farms where big foragers or loaderwagons are depending on well shaped swaths which are finished on time to make sure all forage is safe.
Both Lely’s Profi rakes are designed to withstand this pressure and deliver the optimum swaths to guarantee good performance of high capacity harvesters, balers and loaderwagons.
Rotors with three-dimensional movement for optimum raking
The central delivery rake Hibiscus 1015 CD is a true Pro, which is also due to the unique 3D suspension. It comprises a pivoting head, which gives the rotor a 360° freedom of movement. Both rotors feature a unique wheel assembly. Lely has managed to develop an unrivalled wheel assembly – Octosense – in combination with a 3D suspension.
Octosense – eight tyres guarantee a stable rotor
This wheel assembly (with eight wheels) ensures a stable run of the rotors, irrespective of field conditions and also at high forward speeds. The machine negotiates even the worst terrain unevenness with ease and assurance. Due to the combination of the 3D movement of the rotors and the intelligently engineered wheel assembly, the entire crop is moved, even at very high working speeds.
Hydraulic-pneumatic ground pressure adjustment of rotors
A hydraulic-pneumatic system transfers part of the weight of the rotors onto the frame. This construction reduces the weight on the rotors as well as ensuring improved ground contour following at higher speeds. Pressure in the hydraulic-pneumatic system can be easily adjusted.
The 15 removable tine arms feature the outstanding anti-breakage protection that has already proved its performance on other Hibiscus models. In addition, the tine arm shafts are made of chromium steel, which is twice as strong as the material that is normally used for other makes of rakes.
The tine arms have a lateral configuration and they are supported by ball bearings, spaced out at 320 mm distances. The lateral configuration reduces the stresses that are exerted on the cam track. This cam track itself has by far the largest diameter (370 mm) and it is made of high quality cast iron. The easy access cam track can be simply adjusted. A closed heavy-duty gearbox constitutes the heart of the Hibiscus rake.
Specially shaped double tines for optimum raking
With a view to achieving the highest possible output, each tine arm of the rotors of the central delivery rake Hibiscus 1015 CD Profi is fitted with five double tines. These long tines, made of spring steel, have a 10 mm diameter and their special shape ensures perfect ground contour following as well as the ideal swath shape. No matter how heavy the crop is, the five double tines on each tine arm ensure optimum pick-up of the crop.
Forced linked steering and large low-pressure tyres
Due to the steered rear wheel assembly this giant allows perfect manoeuvring, even in the smallest of fields. The steering system itself stands out by its rugged construction with its large steering rods and king pins. The large low-pressure tyres ensure an ideal distribution of the weight of the machine.
An extremely durable construction
The entire machine stands out from the rest by its remarkably rugged construction. The main frame, made out of one piece, connects the portal headstock with the rugged steering “bridge” for the rear wheels. Two sub frames connect the rotors and the main frame. The A-frame allows the machine to be folded up, while the parallelogram construction gives the adjustable working width as well as very secure locking in the transport position.
Quick in the field, quick on the road
The central delivery rake Hibiscus 1015 CD Profi is fitted as standard with hydraulic drums brakes and high quality tyres for road transport at speeds of up to 40 km/h. In addition, the excellent brake system ensures perfect protection of the rake during work on undulating fields.
V-shaped chassis in field position
The two chassis beams are the first striking feature of Lely’s widest rake, which fold out in a V-shape when entering the field. Two rotors are suspended from each chassis beam and lowered on the left and right-hand side of the beam. In a forward direction, the position of these rotors remains consistent due to the parallelogram constructions. The suspension arms of the rotors can be extended to increase the distance between the rotor and main beam.
V stands for versatility
By varying the angle between the two main beams and by extending or retracting the length of the suspension arms of the rotors, the rake has a wide range of working widths and overlap from which the control computer selects the ideal set-up. This may sound difficult, but it is not…the operator only has to either input or adjust the required swath width and working width; from then on, things move automatically.
The wider, the more stable
By placing the transport wheels to the outside, between the rotors, the ground contour following is excellent. Consequently, major adjustments to field contours can be easily made. Since the long suspension arms of conventional four-rotor rakes are absent, all four rotors have an excellent stability. The wide position of the wheels – combined with 3D ground contour following – provides the best results plus optimum output.
Quickly into and out of transport position
Upon arrival in the field, the rotors are lifted and the transport chassis is unlocked. As the machine moves on, the chassis is steered outward through a central hydraulic cylinder, while the transport wheels remain parallel to the driving direction. During moving of the chassis, the rotors are lowered to the headland position; then they are extended to the pre-set working width.
Saving time on each headland
The Hibiscus 1515 CD Profi has the possibility of selecting a configuration to suit several types of headland shapes so that the computer can lift the rotors individually at the right time. The operator can make quick turns, assisted by the unrivalled stability that is ensured by the wide wheel position. Following the signal of the operator, the computer lowers the rotors individually at the right moment, based upon the previously selected headland configuration.
ISOBUS technology for the user
The computer works through an ISOBUS control system and provides a neatly arranged overview of all functions on the tractor based terminal. Thus, the rotors can be individually lifted quickly and simply, which also goes for adjusting the working width, swath width and headland functions.
Comfortable road transport
The two rear rotors fold up to the inside, reducing the transport width of the machine to 2.50 m in the back, which provides improved road transport and bend negotiation. With the transport wheels placed further back than conventional four rotor rakes, bearing load on the tractor is noticeably increased offering better comfort and save driving.
