FEATURES OF THE CELLI POWER HARROW RANGE

The cross section drawing is of the Maxi power harrow. Different features and specifications may apply to other models, but the general design and principles are applicable across the Celli power harrow range.

RIGID BOX CONSTRUCTION

  • The Celli power harrow body is a one-piece fully-welded rigid box section made of thick, high tensile steel
  • Most other brands construct the box section from two halves that are bolted together; with larger sizes often also requiring additional strengthening structures above the body
  • Celli uses thick plate sizes in the body; 6mm top and bottom in the Super Go and Super Ranger models; and 8mm top and bottom in the Energy and Maxi models
  • Another major Italian manufacturer uses 4mm plate, with 4, 5 and 6mm plate common in many other competitor models, sometimes with thinner plate on top compared to the bottom. This all indicates compromised body rigidity.
Harrow Body
  • The Celli design gives high strength against torsional loads and maintains accurate alignment of the meshing gears within the body.
  • Celli believes it is this rigidity that ensures excellent reliability and service lift
Harrow Body
  • It is for this reason that Celli power harrows do not require strengthening beams bolted from the headstock to across the body

INTERNAL TRANSMISSION

Harrow Phasing
  • The phasing of each rotor shaft was developed by Celli after many years of field development. The Celli timing minimises transverse vibrations and is why Celli power harrows operate so smoothly
  • Many other manufacturers use simple 90 degree timing which is less than optimal.
Harrow Gears
  • The rigidity of the fully-welded body is a major advantage to the internal transmission. Compared to Celli, conventional power harrows have relatively thin gears because they must handle the flexing inherent in a bolted body
  • Thin gears have less meshing height and cope better with the misalignment from body flex
  • Additionally competitiors may use roller bearings to help handle this flexing; obviously strength and durability is compromised with a bolted design
  • Celli power harrows use wide gears for excellent strength and durability.
  • Before you buy your next power harrow, ensure you check out what the main transmission gears look like. Most competitors don't use thin gears just to save cost; its because the flexing in the body can't cope with wide gears.
Harrow Grease
  • A steel plate is located under the top bearing, so that in the unlikely event of bearing failure, the bearing balls don't fall into the main transmission
  • As a result, lubrication of the top bearing by the main transmission lubricant is reduced. Therefore, an additional grease nipple is fitted to the top of each rotor spindle to ensure it is also lubricated by grease
