If a leak is noticed, carefully inspect seals and check oil level. Transmission operation with
insufficient oil may cause permanent damage of the mechanism.
Repair of transmission during warranty period may only be performed at authorised
mechanical workshops.
In addition to periodic inspection of intersecting axis gears, swath conditioner mowers also
require the monitoring of belt tension in swath conditioner belt drive.
DANGER
Before proceeding to check or adjust drive transmission belt set first turn off tractor
engine and remove key from ignition.
Belt tension can be adjusted using the adjustment nut (10) screw (10) of the tensioner bolt
(9). To do this, unscrew the locknut (11) and tighten the adjusting nut (10) on the bolt (9) to
the point where the tensioner spring will be at a minimum tension. The deflection of the belt
(1) measured at the mid point between the pulley on the intersecting axis gear and pulley of
the conditioner shaft should not exceed 10 mm under the pressure of 7.5 daN (kg). If tension
cannot be adjusted, replace belts for new ones. There are three SPB 1525 belts in the
transmission system. To replace the V-belts, loosen the tensioner spring (7) with the
adjustment bolt (10) and remove the belts from the pulleys.
Check the swath conditioner unit belt tension after 2 hours of use. If necessary, tighten the
belts according to the above guidelines.
