7.11 Flail Types
Two types of flail are available:
The F91 H is a cast flail suitable for continuous hedge and scrub cutting. It will also cut grass, but the finish will
be inferior to that produced by the F91 G and the power requirements greater.
The F91 G is a pressed flail suitable for grass and scrub cutting. It can also be used to cut hedges, but
continuous use in this material will noticeably shorten its working life.
7.12 Machine Configuration
The machine can be supplied to be either front or rear mounted and to cut on the right or left side of the tractor.
Conversion to any configuration can be carried out without recourse to specially handed mechanical
components. Some new hoses will be required, refer to hydraulic installation pages in the parts list for specific
requirements.
It is stressed that conversion is a major rebuild and not an in-field adjustment. A workshop with overhead lifting
tackle is required.
Before commencing, drain the hydraulic system and empty the reservoir.
Important Points
The pump/gearbox assembly is horizontally mounted. For left front and rear right builds it is mounted with the
pump away from the tank.
For right front and rear left builds, it is mounted with the pump towards the tank.
The hydraulic hoses to the flail motor and the angle ram are always routed up the front face of the main arm
crossed over at the pivot and down the rear face of the dipper regardless of machine build.
The flail head is dispatched with the motor mounted inboard. If converting right to left or vice versa and if an
inboard mounted motor is an important operational requirement, it will be necessary to rebuild the flail head
with the motor mounted at the opposite end.
