Description

Blackstone RMOH 125 Tractor-Mounted Flail Mower

The RMOH 125 hydraulic displacement flail mower is an agricultural machine designed to cut and shred vegetation such as trees, shrubs, bushes and grass. Its distinctive feature is its hydraulic displacement system, which allows the flail mower to be moved laterally for precise and efficient working.

This machine is equipped with a strong and durable frame, which is fitted with a sophisticated cutting system with high-speed rotating hammers for precise cutting of vegetation. The hydraulic displacement system, fully integrated in the frame, allows the flail mower to be positioned laterally with extreme precision thanks to the hydraulic piston that accurately and safely controls the movement of the machine.

The Blackstone RMOH 125 flail mower is suitable for agricultural use on cultivated land, meadows, pastures and for the maintenance of green areas such as parks and gardens.

Additionally, it is supplied with the cardan shaft, ensuring a safe and reliable connection to the tractor.

Suited for mainly hobbyist work, the Medium series flail mower is equipped with hydraulic side-shift, 3 drive belts and a rear roller.

Technical data at a glance:

  • Effective working width 125 cm
  • Effective overall width (with side skids fitted): 140 cm
  • Weight: 265 kg
  • Side hydraulic shift
  • 1° category 3-point hitch
  • 3-belt drive transmission

Inspectionable Bonnet and Side Belt Drive

The Blackstone RMOH 125 flail mower's bonnet, located at the top of the cutting compartment, allows access to the machine's internal components in a more convenient and practical way for maintenance, inspection and cleaning purposes from any crop or vegetation residue.

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)

Detail of the gearbox:

3 - SAE 80/90 oil filler cap and vent


ATTENTION!

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).

Hydraulic Side Shift and 3-point Hitch

The flail mower is equipped with hydraulic shift.

The 3-point hitch slides on a sturdy tube that runs the full width of the flail mower.

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 rotor speed and the high number of hammers (hammer flails), it reduces the wave effect of the turf and has an excellent shredding action.
