2018 Pottinger TOP with a single rotor TOP 421 A Toptech Plus

Large cam track PTTINGER offers a cam track diameter of up to 420 mm and a bearing spacing of up to 700 mm on the tine arms. These properties give the tine arms maximum strength with minimum stress on the arm bearings. The cam track can be infinitely adjusted to different forage volumes and changing harvesting conditions. The rotor gearbox runs in a sealed grease bath.

No lubrication required. TOPTECH PLUS eliminates leak problems and requires neither oil checks nor oil changes.

Optimised for smooth control of cam rollers. No sudden inclines in cam track so control arm follows cam track smoothly. Maintenance-free steel cam rollers, high strength cam followers and wide spacing of the tine arm bearings guarantee high strength and low stress to the bearings. The tine arm bearings are also maintenance-free.

The heavy-duty tine arm cross-section is strong and resistant to twisting and bending. Tidy raking work is provided thanks to 11 / 12 / 13 tine arms per rotor, depending on the working width. The tine arms are removable to reduce height for transport and parking.

The working height of TOP rakes can be adjusted from the standing position using a hand crank. These are easily accessible and maintenance-free. A height indication makes it easy to ensure that both rotors are the same height on twin rotor rakes.

The whole tine arm can be exchanged quickly and easily in the event of any damage. Just undo the bolts to slide the tine arm plus cam roller out of the rotor casing.

• No problems with oil leaks.

• Ready for action again in no time.

Raking has a decisive influence at the end of the harvest chain on how clean the forage remains. The tines must not contact the ground; instead they rake the forage carefully out of the sward.

The tines are positioned straight at the ground directly under the tine arm, without any need for a steep offset angle. Due to the resistance of the forage, they are pressed back slightly but do not rise upwards under load therefore the tines produce exact raking results. These tines do not need to be set so deep as others to rake tidily. This means less stress on the cam track and cam rollers. Resulting in both the sward and forage are both treated with care. The long tines are drawn smoothly out of the swath for a perfect swath shape. The outer pairs of tines are slightly shorter so that they do not contact the full volume of forage and the load is lower. The three inner dual tines are used for precision work.
