Rake
Only the best goes into the swath
At the end of the harvest chain, it is a matter of getting all the forage lying in the field into the swath. But only the forage. Raking and collection losses must be kept to a minimum, while at the same time dirt ingress must be avoided.
To do this, the tines on the rake should not draw the forage over the ground, but lift it slightly. The distance between the tines and the ground should be 3.5 cm at the beginning and 2 cm at the end of the raking arc. This gradient towards the swath side ensures clean raking with the lowest possible dirt ingress over the entire working width right up to the swath. Precise ground tracking is needed to ensure that the set distance is maintained under all operating conditions.
Our range of TOP rotary rakes feature unique ground tracking and precise rotor inclination adjustment on the tandem axles of the rotor chassis so you can rake the forage onto the swath without contamination.
Ground tracking
From the point of view of the tines, the wheels on the rotor chassis inside the tine arc do not react to bumps in the ground until it is already too late. Regardless of whether it is a three-wheel or six-wheel chassis - due to the width of the tine array, the front wheel is located around three quarters of a metre behind the arc of the outermost tine.
The only thing that helps here is a jockey wheel running in front of the tines. The MULTITAST jockey wheel system from PÖTTINGER detects bumps in the ground ahead of the outermost tine and tilts the rotor upwards when there is an incline. This provides the ideal gap between the tines and the ground. Together with a wide rotor chassis, smooth running of the rotors is guaranteed.
Cleanly collected crop
PÖTTINGER tines are angled forward in a dynamic position. Due to this shape, they actively lift the forage away from the ground - like a pitchfork. As more forage is collected, it rides up the tine unhindered. As a result, the forage is not dragged over the ground along the entire arc of the raking action. Dirt ingress and disintegration losses are minimised.
The special feature of the PÖTTINGER tines is that they pass just above the ground directly below tine carrier at only a slight angle. This means that they do not lift upwards to avoid high volumes of forage. They pick up the crop cleanly even in difficult conditions.
Loose and airy swath placement
The large dimensioned cam track with a diameter of up to 420 mm provides the basis for forming loose and airy swaths. The large cam track diameter with its smooth ramps makes sure that the tines exit the forage ergonomically to place an airy swath. This means that the forage can be raked into a swath in good time and yet it can still dry in the wind.
The cam track is infinitely adjustable. This enables flexible adjustment to different types of crops and harvesting conditions.
"I run an organic farm with 120 hectares. I also have a sheep farm and a contracting business. That is where I use the TOP 1252 C. A clean and tidy swath and a good raking quality are essential for high output and clean harvesting, which this rake delivers in full. Because forage quality is what matters most to my customers, I have equipped my rake with the MULTITAST jockey wheel system."
