Alamo BUSH HOG RMB 1660 Operator's Manual page 146

Extra care must be taken when working in 'SLEW' mode with the reach fully in – IT IS
POSSIBLE FOR THE FLAILHEAD TO HIT THE TRACTOR OR MACHINE FRAME.
8. Rotor Operating Speed
Ensure that the rotor control lever is in the 'STOP' position before engaging the PTO shaft. Allow the oil to
circulate for a minute or so before operating the armhead levers. Position the fail head in a safe position,
increase the engine speed to a high idle and move rotor control lever to 'START'. After initial surging the rotor
will run at an even speed.
9. Forward Speed
The material being cut determines tractor forward speed. Forward speed can be as fast as that which allows
the flail head sufficient time to cut the vegetation properly.
Too fast a speed will be indicated by over frequent operation of the breakaway system, a fall off in tractor
engine revs and a poor finish to the work leaving ragged uncut tufts and poorly mulched cuttings.
