Drive Belts & Power Transmission
The FM Series Flail Mowers utilize two drive belts (2 x BX41 / 16 X 1115), driven through a centrifugal clutch, with a spring tensioned idler system
to compensate for wear of the belts and pulleys.
The drive belts are designed as a 'weak-link' in the drivetrain, such that the belts will fail before damage is caused to the engine if a foreign object
is encountered or rotor entanglement occurs. Drive belts are a wearing part and as such are not covered by the machine warranty.
Belt Replacement
New Type Tensioner (09/14 - Present)
1.
With the height at the highest setting, this should allow the easiest access without removing the wheels. Alternatively, remove the
wheel on the engine side, once the machine is suitably supported with chocks or similar.
2.
Remove the belt guard by loosening the 2 17mm bolts marked 'B', and fully removing the bolt marked 'A'.
3.
Slacken the tensioner adjuster bolt using two 17mm spanners, shown as part 'C' above. The tensioner adjuster should be slackened to
such a point as the spring can be removed by hand from the tensioner arm, as shown by the right-hand image above.
NOTE: ALWAYS REPLACE BELTS AS A PAIR.
4.
At this point the tensioner arm will be free to rotate, allowing full access to the belts. The
belts can then be removed by 'winding' over the lower pulley. Take care when removing /
replacing belts not to lever the belt or damage in any way, as this will greatly reduce belt
life. The belts should be able to be fitted by hand, without using any forcing tools.
Replacement is a reversal of removal. Belts should be tensioned to 5mm deflection at
15kgf. As a rough guide each belt should deflect approximately 5mm under medium
thumb pressure applied at the midpoint of the belt between the two pulleys. Both belts
should deflect to the same degree.
