HP 180-280 KW 132-206

Rotary tiller Franngor version

Our strong points

The folding rotary tillers Tiger 280PF are HC (High Clearance) machines: they are characterised by a wide gap between the blades and the bottom of the main frame. This feature allows to avoid soil build-up effects even in difficult conditions (on sticky soils or in case of abundant crop residues) as well as to limit the required horsepower and therefore the operational costs.

  1. The central frame is a critical feature of all folding units. That’s why Celli has developed a special heavy-duty central frame which has no rivals in the market. Its design ensures a long-lasting high resistance to torsional stress and consequently a top-quality performance of the drive gears.
  2. The structure of the two side units is equally sturdy and extremely tested.
  3. The drive gears have been long tested under the most different working conditions, since most of them derive from the highly successful Celli rotary tillers series Tiger 190.
  4. An exclusive feature of Celli folding rotary tillers is the very small gap (5 mm wide) at the centre, between the two side units, which was specifically designed to avoid a typical problem of folding machines: the track which is often left at the back on tilled soil, due to the central gap between the two side tillers. Furthermore, the machines are equipped with two front, well-shaped tines, which help to till and shift the soil sideways.
  5. The rotors have undergone extensive field-testing in the most difficult working conditions all over the world.
  6. The rear rollers are generously dimensioned – cage rollers: 500 mm, packer rollers: 550 mm, so that they can guarantee a regular work and a perfect levelling effect even on wet soils.
  7. The rear rollers adjustment is carried out through four hydraulic rams, which allow to vary the working depth directly without interruptions.
  8. The tailgates are specifically designed to allow a wide range of adjustments and to ensure an ideal performance of the machine on all soil conditions.
  9. The standard machines are equipped with a hydraulic tailgates adjustment, through which the soil refinement level can be easily controlled during work. This adjustment system includes a spring shock absorber.
  10. Like all Celli folding machines, this model is fitted with safety stop valves on the hydraulic rams, in order to prevent it from falling over, when folding and unfolding the side units, in case the oil pipes collapse.
  11. When the unit is folded, the safety clamps automatically lock the machines upright. When the operator needs to unfold the tiller, the safety clamps can be hydraulically released from the tractor seat.
  12. Double flanges and thicker blades can be mounted on request on the rotors. They are particularly useful when the machine is operated on stony or extremely hard soils.
  13. The Tiger 280PF is equipped with III cat. swinging arms, which ensure the rigidity necessary to safely manoeuvre the machine both on the field and in folded position on the street.

In addition to the rotary tiller version, a Frangor version is available in the same working widths, fitted either with spikes rotorshaft (shown in the picture) or with straight tines rotorshaft. This Frangor version is ideal for the finest seedbed preparation.

Technical specifications

Rigidity of the main frame

The rigidity of the main frame is extremely important to guarantee folding units reliability and long life. The torsion, especially at the ends of the machine, is very significant and it usually is the main cause for a rapid deterioration of the machine.

Central frames

Each folding unit is made of 2 side units and 1 central frame. The central frame is made on purpose for each model, depending on the torque it is supposed to bear. The 2 side units are kept into position by the central frame with pins of large diameter, coupled to bushes which are cemented and heat treated.

“NO GAP” design

The most serious problem for folding machines with a horizontal axis is the strip of un-tilled soil left between the 2 units. Celli has managed to solve this problem almost completely by reducing the gap in the middle of the 2 coupled side units to a few millimetres, by designing special side plates and special rotors.

“HC” concept

The Tiger series have been specifically designed to have as much space as possible (“High Clearance”) between the frame and the working components (blades, knives or spikes). This feature minimise the possibility of jamming even in heavy soils and also when crop residues are abundant.Furthermore faster working speed and higher working depth can be achieved, thus increasing the yield per hour.

Transmission with 3 reduction gearboxes

The solution adopted by CELLI guarantees an adequate reduction ratio without over-loading the side drive shafts: the central gearbox works as a diverting drive, whilst most of the drive reduction takes place in the side gearboxes. An extra drive reduction takes place in the side transmission.

Rear rollers of large diameter

They guarantee excellent soil levelling and proper machine “floating” even in light soil conditions.

ROTARY TILLER

FRANGOR

High quality blades rotors

Manufactured with very thick pipes onto which high quality flanges are welded (Fe 510 or wear-less steel OX 812). In the production line automatic welding machines optimise welding operations and assure good specifications: hardness of the materials and their resistance to shocks are perfectly balanced.

High quality spikes rotors

Manufactured with very thick pipes onto which are welded high quality flanges straight knives rotors) or forged supports spike rotors). CELLI can say that its automatic welding machines optimise welding operations and assure good specifications: hardness of the material and its resistance to shocks are perfecly balanced. Two Frangor rotors are available: a spikes and a straight tines rotor. The spikes rotor is very versatile, and it effectively works in dry-hard soil as well as in wet soil. It doesn’t fear stones and usually it absorbs less power than straight tines rotor. Straight tines rotor s recommended when maximum soil efinement is required. It performs better n dry soil and it absorb more power than spikes rotor.

Reduced power absorption

The special design of blades and Frangor rotors, the helicoidal timing if respective tools, the design of the tools themselves, all these technical features contribute to reduce power absorption and vibrations, allowing a better performance of the machines.

Versatility

Versatility of application

The standard characteristic of CELLI machines is their versatility. They can easily be used both in wet heavy soil as well as in dry hard soil. Their adjustments and their technical specifications allow quick adaptability to changing working conditions.

Versatility of application

Frangor models equipped with spikes rotors can easily work both in dry hard soil and n wet heavy soil, with no risk of jamming. They are resistant to stones and they also offer a good soil crumbling whilst requiring ow horse power.

2 rotating speeds always available

All models are equipped with side gearboxes with 2 rotation speeds, which can be easily changed within minutes simply by inverting the gears.

Oil cooling kit (optional)

All folding units can be equipped with an oil cooling kit, which allows to work in difficult conditions for long non-stop period, without any risk of damage for the transmission gears in the central gearbox. The oil filter preserves the oil quality and viscosity, thus extending bearings and gears life.

Rapidity of commissioning and adjustment

It takes just a few seconds to open and to fold the machine, as well as other adjustment operations, and all of them can be carried out from the tractor’s cabin.

Reasonable weight for transport on public roads

The total weight of machines, especially bigger ones, should not exceed reasonable limits, so that they can be transported on public roads without any problem. Therefore, the reliability of a machine must be sought through optimised sizing and quality materials.

Commercial points

Special attention to safety aspects

The machines are lifted by very strong hydraulic jacks equipped with block valves. Once they have been folded, they are blocked by mechanical safety locks. Then, prior to transport, a further mechanical locking device can be manually activated.

High productivity

The array of solutions available allow to choose the ideal machine needed for each specific work, always keeping the max yield per hour in relation to the machine power.
