Thanks Blue Power.
Is that due to energy loss in the mechanicals,
or because the flail is chopping the material up finer, or both?
Not trying to hijack the thread here:
No a flail mower does not require more mower than a rotary mower with belt drive
Power use is less and the energy used rotates more cutting edge than a rotary mower
because only half a rotary mowers blade/cutting edge is contacting the grass or brush to be cut.
A flail mower will leave hardly any clippings and you can mow over them and shred them even finer
due to the pressure gradient created by the lift created by the side slicers of a finish flail mower.
A flail mower depending on brand, end use and final pulley diameter
rotating the flail mower rotor will reach 2,200 RPM or more.
A rear mount flail mower for receives it power from a 540 RPM power take off
where it is delivered to a right angle gearbox which then transmits this energy
to the drive pulley with then delivers this power with V belt to the larger in diameter
driven pulley which rotates the flail mower rotor which spins up to 2,200 rpm or greater depending on
the intended use being mowing, crop shredding, forestry mowing etc.
Depending on the number of knive stations and whether it is a finish cut flail
mower you will have much more cutting edge slicing the grass blades with the
following row cutting more grass as the mower advances or reverses.
My four foot finish cut flail mower has 64 knife pairs and each side slicer has 3 inches of
cutting edge with 6 inches of cutting edge in one side of the knife pair and 384 inches of
cutting edge on one side of the knive pairs so think about that issue when you look at a
rotary mower or rotary brush mower when you are looking at a rotary mower that has a
five foot width (NOT WIDTH OF CUT)
Oh and a flail mower pr flail chopper only has two bearings that support the flail mower rotor
versus a bearing stack on the rotary mower or brush mower spindle
A mid mount mower will have a mid PTO that is rotating at 2,000 RPM plus or minus
to a right angle gearbox which then delivers the force to the three pulleys/spindles
via V belts which rotate the spindles and the blade tip speed is what does the massacre
of good turf tearing the grass blades.
