Strong reasons why a rotary rake is counterproductive for your farming.

The established rotary rake technology has been on the market for over 50 years. Its technical development is completely exhausted. The challenges of practice and the higher quality awareness of farmers are increasingly putting this technology under pressure.

1. Impurities

unfavorable bacteria and fungi, dust, earth, sand, stones, foreign objects,manure and muck particles, mice, rotten undergrass

3. Losses

leaf losses, crumble losses, raking losses, fermentation losses, losses at thefeeding table, wear on machines

3. Unreliable in difficult conditions

moist and soft soils (flood plains and boggy areas), uneven and unrolled fields, dry and stony topsoil, low peat density, cover crops, corn straw as well various special crops (hemp, sorghum)

4. Deficits in performance and other factors

compacted / twisted swath, limited working speed, higher power requirement, worse after-drying at the swath, not flexible in working width and direction of swathforming

5. Endangering animal health

contaminated feed causes inflammation, fertility and claw problems, reduces animal performance, digestive issues with horses

The challenge "soil condition"

Rotory rake


Extremely dry / hard

Rotor runs unsteadily, jumps, soil splashes on contact with the ground

Elastic pick-up dampens, soft contact due to dragging tines

Extremely wet / soft - boggy soil

Rotor undercarriage sinks in, tines work deeper

Sliding plate with large contact surface, PU does not sink in

Gravelly soil

Increased risk of small stones due to stiff tines and high speed

Very low risk of small stones being lifted by dragging tines

Stony soil

Stones on the surface are necessarily pushed into the swath

Stones are only lifted when they come to rest on the forage mat

Sandy soil

Will be dragged, pushed, carried along

Almost no contact due to flexible pick-up – in case of ground contact this is very gentle – sand stays behind

Loose topsoil

Easily dragged along due to high tine speed and forage wall in front of the tines

Stays in place due to dragging tines and low tine speed

Docked areas lengthwise (hilltop position, trough position)

Rotary rake through the trough -> massive ground contact at the front despite cardanic suspensionRotary rake on the hilltop -> raking losses.

Sliding plate close to the dragging tine and four-joint suspension guarantee minimum ground contact and lowest raking losses.

Cupid areas transversely (hilltop position, trough position)

Top: raking losses laterallyTrough (road embankment): extreme ground contact.

Top: raking losses laterallyTrough (road embankment): extreme ground contact.


The rotor tilts, either leaving fodder on the uphill side or in contact with the ground on the downhill side.

No raking losses or soil contact

Ruts (forage in the tractor track)

Forage losses unavoidable – if these are to be minimised high increase in contamination

Forage losses unavoidable – if these are to be minimised higher increase in soil contamination (aggressive tine)

Non-rolled arable land (stones, embankments)

Stones are easily carried away, embankments are levelled and the forage contaminated

Stones are largely left lying around, dragging tines deflect on dams

Unevenness in small spaces (holes, footprints, ruts, dams, etc.)

Rotor undercarriage falls into depressions => massive ground contact, rotor undercarriage on hilltop -> forage losses – the remainder is shaved or levelled

Smooth running due to flexible pick-up and sliding discs over unevenness, no sagging, raking losses and dirt ingress are minimal

Grazed areas

Extreme dirt ingress through holes and dams from footsteps

Low dirt ingress due to flexible pick-up, sliding discs and dragging tines with low tine speed
