Lely Power Harrow Roterra 35 / 45 Series

DESCRIPTION

Lely Power Harrow Roterra 35 / 45 Series


The Lely Roterra 35 – 45 Series Power Harrow is a new design with a heavy modular3-point hitch and reinforced roller arms.There is a large distance between the bearings in the trough, which means the bearings are subject to less forces, resulting in extra stability. This extends the lifespan of the bearing sand large forces can easily be absorbed.
Tines are hardened in 5 zones for extra toughness and extended lifespan. In the top region the tines are very tough while, with a transition from the middle, the tines get harder and more wear-resistant. This makes the Tulip club tine extra durable and at the same time tough enough to handle the most extreme conditions. It has the widest range of gear sets available on the market. An optimal rotor speed can be set in all soil conditions. It is always possible to work with the most efficient engine speed of the tractor.
There are 4 rotors per metre for alow power requirement and thus fuel saving.Adjacent rotors overlap each other. It has reinforced roller arms with 20 mmpins and floating system with many settings. The new design heavy modular3-point hitch has a compact build and linkage. Many ways to mount are provided.Optional: the hydraulic linkage provides the ability for a compact mounting of Roterra and seed drill that makes driving on the road safer.
A spring-loaded rotor guard ensures that stonest hat come in front of the machine are pushed down and so the rotors are protected. If a stone would end up between rotors and the rotor guard, it can pivot forwards to let the stone pass through the machine.
The Walter scheid PTO shaft with cam-type-cut-out clutch or optional Tulipmatic shearpin automat. The advantage of the Tulipmatic is that time after time,after overload the connection is broken at the exact specified moment. This reduces thechance of damage as a result of overloading the machine.
The side deflectors are adjustable so that a perfect connection with the previous working pass is obtained.They are also foldable for road transport.This way a Roterra 300 stays 300cmduring road transport.
The dragging club tines have a special round shape. The shape avoids smearing ofthe soil, and clods are broken up without the natural layers of the soil structure beingaffected. Furthermore the dragging position keeps the lower layers of soil where theyare, and stones are pushed downwards rather than upwards. Due to the round shapeof the tine, fuel is saved because not once the tine will have a flat surface facing thedriving direction. This makes the Roterra pull much lighter.

Special benefits

• Patented club tines: due to the shape, side-fixation, material and production technique, the tines guarantee high quality and long life. These club tines are fitted by a single allen headed socket bolt and an unique captivated self locking nut. Because the bolt is accessible from the side, the tines can quickly and easily be changed thanks to the Easy lock system by means of a power tool or socket. Fuel saving up to 20% in comparison with knife tines.
  • Heavy duty rigid torsion-free gear trough with flanges lid, large diameter shafts and bearings as well as a large spacing between the top and bottom bearings.
  • Gear trough completely sealed to ensure no contamination of the drive gear lubrication. Incorporating self lubricating, double sealed, heavy duty bearings.
  • Patented spring-loaded rotor guard: stones and other objects are pushed down and can pass through the rotating tines.
  • Foldable floating soil deflector: working width = transport width.
  • Floating system: if necessary, the Roterra power harrow can break out upwards independently from the roller.The roller continues to follow the ground.
  • Rigid portal head stock: centre of gravity is positioned closely to the tractor, makes working with a less powerful tractor possible.
  • Rotor speed: quickly and easily changeable gears.
  • Compact engineered: headstock and support frame suitable to mount secondary equipment like seed drills or planters, offers seeding or planting in one pass.

Points of interest
• For the Roterra 302 and 352 the heavy linkage of the 402/452-45 has be ordered if also the headstock of the55 series is ordered (article number 705-930-057).
• For machines without central drive (45 series) which are used in combination with a seed drill a shearpinautomat Tulipmatic is recommended.
• Shearpin automat Tulipmatic is recommended in soil with stones.
• The mentioned powers are measured on the PTO-shaft.
