Comb rakes from BB-Umwelttechnik: Gentle, clean, efficient

Thanks to the cam rake principle of our Clementer, the forage is lifted off the ground and conveyed forwards and to the side. Due to this comparatively gentle lifting of the cut material, no stones are picked up and contamination can fall out of the forage. In contrast to conventional technology, no material is dragged across the ground. The result is an airy windrow without forage compaction. The short design with the depth control mechanism positioned very close to the forage pick-up creates precise ground contouring and ensures clean work even on uneven terrain. Many well-thought-out details make our cam rakes easy-puling, smooth-running and simple to operate.

The feed is deposited to the right or left, depending on the model. Our rakes are available with working widths from 2.50 to 7.50 metres.

Features at a glance

Clean forage

The comb rake principle keeps the cut material particularly clean. With front-mounted attachment, the forage is also not driven over or into the ground.

Extremely gentle on forage

The particularly gentle deposition of the forage onto the swath leads to improved forage quality.

Airy swath

The loose swath ensures that the cut material can dry out particularly well.

Low power consumption

Our comb rakes are exceptionally easy to pull. Well-conceived drive technology guarantees minimal energy consumption combined with maximum working width.

Modular construction

Thanks to the well-thought-out modular design, many machines can be produced with identical components.

Perfect ground adaptation

The feeler wheels running close to the swath drums allow for very good ground contour following.

Steplessly adjustable tracking wheels

Each feeler wheel is height-adjustable via a hand crank. The hand crank is secured against self-rotation by a simple mechanism.

Quiet driving behaviour

Wheels measuring 18 x 8.50 x 8 ensure a smooth and gentle ride, even on uneven or damp ground.

Diaper cover

To prevent fodder from wrapping around them, a wrap guard is fitted at every moving point. All rotating parts on our Clementers are equipped with high-quality SKF ball bearings. 

Own oil supply

Generally, all comb rakes are equipped with their own oil supply. A large-volume hydraulic oil tank, oil sight glass, return flow filter and generously dimensioned lines ensure reliable operation of the mower. A thermometer in the oil sight glass provides information about the oil temperature.
On request, the drive of the Clementer can also be provided directly via the tractor hydraulics.

Simple operation

A front-mounted rake can be easily lifted and brought into the transport position via the tractor's front linkage. When using the 2-piece or 3-piece Clementer Standard, the outer swath drums are optionally raised automatically by sensor control only to the extent that driving over the swaths without touching them is possible.

Maximum flexibility

With rakes having two or three swath drums, the outer drums can be attached and detached tool-lessly via a quick-coupling system. This allows the working width to be flexibly adjusted.

Frequently asked questions

How fast can you travel with a BB-Umwelttechnik comb rake?

It always depends on the conditions of the area. In general, higher driving speeds are possible compared to a rotary rake. Under very good conditions, this can be up to 16 km/h.

Does braid formation occur when swathing with a comb rake

In principle, the cam rake has no problem with rope formation. A tendency towards rope formation, if anything, only occurs with very long and damp material. This tendency can be countered quite effectively by using a higher rotor speed and driving speed.

How to handle the headland when driving a BB-Umwelttechnik comb rake?

More space is required at the front, as it takes longer for the comb rake to empty completely. In most cases, this is not a disadvantage, as there are no large amounts of feed at the beginning of the windrow. This is gentle on the forage wagon and the chopper.

How much does the BB-Umwelttechnik comb rake weigh?

The weights are indicated in our brochures, e.g. a Clementer 550F weighs approximately 1,100kg when fully equipped. Warning! Decentralised weight distribution on the machine!

What are the requirements for a tractor if you want to work with a comb rake (550 F) from BB-Umwelttechnik?

Stable front hydraulics (machine with 1100kg and decentralised weight distribution!)
7-pin socket on the front (for electrical pre-tensioning only)
Ideally, a T-piece in the pressure line of the front hydraulics (only for electrical pre-selector control).
Integrated hub relief mechanism or attachment points for relief springs
Weight class from 4 tonnes, rear ballast may be necessary!

What are the advantages of a comb rake from BB-Umwelttechnik compared to conventional swathing technology?

Completely minimised forage contamination by lifting the forage and minimal ground contact of the tines

The dirt is already falling out before the material is in the swath.

No running over the feed when front-mounted

Minimum power requirement at the PTO

Outstanding contouring through depth control wheels running close to the swath drum

Good wipe quality is ensured even at high driving speeds

We lift the material off the ground and toss it through the air to the side, which creates a loose, clean windrow.

Good drying due to a loose windrow. 

Relaxed working because the machine is always in view.

Quick attaching and detaching of the right swath drum, for high flexibility!

Minimal space required when parking the machine.

How does a comb rake from BB-Umwelttechnik differ from a rotary rake?

Due to the loose, airy placement, the swathe is more susceptible to wind than a conventional swathe. 

Can you also make silage swaths with the BB-Umwelttechnik rake?

Yes, thanks to the standard design with a tine spacing of 50 mm, even very heavy materials such as arable silage can be swathed.

For what purpose are which tines needed on the comb rake from BB-Umwelttechnik?

Standard: slurry rod 6 tine holders + tine spacing 50mm to Model„Silage 6“(for very heavy forage (field forage), high driving speeds, perfect raking result)

Per reel 6 tine holders + tine spacing 80mm to Model„Hello 6“(for hay and wilted silage (grown grassland), high driving speeds, minimal forage contamination)

Is there an overload protection on the BB-Umwelttechnik comb rake?

Yes, the swath drums stop automatically via a pressure relief valve if the load is too high. This ensures reliable protection of the machine. 

Why doesn't BB-Umwelttechnik build a front centre rake?

If the two swath drums were to form a V at the front, they would have to be folded towards the middle and forwards for road transport. On the one hand, this would restrict visibility so significantly that it would be impossible to take part in road traffic. On the other hand, the machine would project extremely far forwards.

Can you rake uphill with the BB-Umwelttechnik comb rake?

Yes, that is possible. However, the rotational speed should be increased when calculating upwards. With the Clementer 550 F, it should be noted that drift on a slope can be relatively significant.
