6.1.2
Flail Types Available
The machine is equipped with 38mm Twisted flails as standard, see Figure 6.2. The twisted flails are suited to
lighter working on longer, fine grass giving an angled finish with the ability to cut material up to 20mm (0.8
”)
diameter.
Rolliflail machines are able to be optioned with a 51mm Long Scoop flail, see also Figure 6.2. The long scoop
flail is able to create a low and level cut working again with the ability to cut material up to 20mm (0.8“) diameter.
The design of the mower is such that during work the rotor unit cuts in reverse rotation (See section 1.3) and
raises the cut material over the rotor towards the back of the cowl. In doing so material falls back into the rotor
and is cut again several times until it is small enough to be discharged from the rear of the machine.
The rotor unit should be inspected prior to work on a daily basis to check for damaged or missing flails
– always
replace damaged or missing flails immediately. Flail bolts should be checked for tightness on a regular basis
and re-tightened as required before attempting to use the machine.
Figure 6.2
WARNING!
When replacing worn or broken flails, always replace opposing pairs and use a new bolt and
locknut with every installation. This minimises rotor out of balance and ensures nut retention.
WARNING!
Checking of rotor components should only be carried out with tractors engine switched off,
starting key removed and the PTO shaft disconnected.
Always ‘prop up’ the machine using
suitable supports before attempting to inspect or work on components underneath it.
6.1.3
Tensioning Of Drive Belts
It is important for both optimal machine performance and long-lasting belt life that belts are correctly tensioned at
all times. On the Rolliflail range, the belts must be tensioned manually and re-checked periodically.
WARNING!
Checking of belts and drive components should only be carried out with tractors engine
switched off, starting key removed and the PTO shaft disconnected. Never attempt to run the
machine with the belt guard removed
– Replace guard after tensioning before starting the
machine.
