Blackstone BM-CD 140 - Tractor-Mounted Flail Mower

The Blackstone BM-CD 140 medium-series flail mower with hydraulic side shift is an agricultural machine designed to cut and work medium-sized greenery, i.e. grass, straw or crop residues. The hydraulic displacement system allows the position of the flail mower with regard to the tractor to be adjusted in order to suit different working conditions. This system makes it possible to place the machine to the right or left of the towing vehicle, allowing a greater working width to be achieved or to adapt to particular ground conditions.

This configuration allows the operator to cut efficiently and accurately along field edges or in narrow areas, reducing the need for subsequent passes or additional manual work. Furthermore, the use of a hydraulic system simplifies adjustment operations and allows more precise control of flail mower positioning.

The Blackstone BM-CD 140 flail mower can be used in agriculture on cultivated land, meadows, pastures or for the maintenance of green areas such as parks or gardens.

On this model it is possible to install a practical inter-row disc to optimise the various shredding operations, thanks to a holder that is supplied as standard.

Medium-sizedseries flail mower, suitable for mainly hobby use, equipped with hydraulic side-shift, 3 drive belts, rear roller and double opening bonnet.

TECHNICAL DATA (brief overview):

  • Real working width: 140 cm
  • Real width (side skids already assembled): 160 cm
  • Weight: 302 kg
  • Side hydraulic shift
  • 1° Category 3-point hitch
  • 3-belt drive transmission

Hydraulic side shift and 3 point-hitch

The Blackstone BM-CD 140 flail mower is equipped with hydraulic shift.

The three-point hitch slides on two sturdy tubes, both 117 cm long.

Focus on the piston that controls the hydraulic shift (32 cm) of this flail mower. This allows the position of the cutting unit to be adjusted and moved laterally compared to the machine frame. This feature allows the cutting unit to be aligned with the vegetation to be cut and to work efficiently even under the most demanding shredding conditions.

Universal standard PTO ( 1 3/8" Z6 )

Universal joints suitable for all tractors on the market.

Focus on the sturdy 1° category 3-point hitch,

Wheelbase size 61 cm.

Height of the two lowest pins from the ground: 30 cm

Height from the highest pin from the ground: 76 cm

Side belt transmission and geared reducer

This flail mower has been designed to support an inter-row disc (available separately on the site), which can be attached to the machine by means of a practical bracket (supplied).

Gearbox in oil bath. The housing is made of cast iron, while the internal gears are made of hardened steel.

This machine is equipped with a freewheel device (or additional joint) built in the gearbox; this ensures a long service life of all the moving parts of the machine, preventing the kickback that would be caused by changing from 540 rpm to 0 rpm and allowing the rotor to turn freely until it stops.

3-belt side transmission (most tractor-mounted flail mowers in this weight category are equipped with standard 3-belt transmission)

Focus on the side belt protection guard.

Focus on the transmission side grease nipple.


The gearbox of this machine can contain no more than 1.2L of lubricating oil.

Please carefully read the instructions manual before starting the unit.

Standard 1 3/8” z6 PTO (suitable for all current and recently manufactured tractors): whether you own a particularly old tractor, make sure that it s equipped with the same PTO and with standard clockwise rotation (right-side).

Stabilisation accessories - rear roller and side skids

Height-adjustable rear supporting roller provided on standard equipment.

Support roller protection rod.

Focus on one of the two standard adjustable side support skids.

Gearbox in oil bath.

B-section 3-belt side drive.

Focus on the protective casing, with central opening for grease nipple.

Focus on the side supporting device with hammer rotor internal locking bearing.

Focus on the external rotor, with central opening provided with greaser.

Sturdy set of front protection slaps made of shaped steel.

Focus on the external anchoring of the rear roller, with central opening provided with greaser.

Cutting tools: hammer flails

No. of hammers fitted on standard equipment: 18.

Focus on the cutting hammers, mounted on the rotating roller.

Hole width: 16 mm.

Blade width: 13,5 cm

Weight of the single hammer flail: 800 g

These hammers are fixed to a rotor inside the machine.

It finely shreds grass and twigs, while simultaneously rolling the turf. Thanks to the high number of rotor revolutions and the number of hammers (hammer flails), it allows reducing the wave impact of the grass cover and performing excellent shredding operations.
