Bredal F4 - Spread Unit Maintenance and Lubrication; V-Belt Tightness Check; Headland Gear Function Check

62
It is important to keep the spread unit properly maintained/lubricated. There is a general time interval for how oen the spread unit should be
lubricated. Otherwise, it is important to lubricate the headland gear, etc., especially aer washing the spreader and before putting the spreader
into storage for winter. Also, it is important to test the headland gear’s function when the spreader is attached to the tractor and aer a long idle
period. Check the tightness of the V-belts at regular intervals. The procedures for inspecting and maintaining the spread unit are shown below.
A spring to tension the V-belts is attached to the right side of the spread unit. Tension
the spring to 93–95 mm when the spread unit is cold. Check the tightness aer every
20 hours of operation. Re-tighten if the spring is measures more than 95 mm.
MAINTENANCE AND LUBRICATION OF SPREAD UNIT
> V-belt tightness
Check the headland gear by rotating the le disc aer switching between eld and
headland spreading. If the headland gear is activated, the le disc must rotate more
slowly than the right disc. If eld spreading is active, the discs must rotate at the same
speed. Aer switching, a distinct “clunk” sound will be heard when rotating the disc to
indicate that the claw clutch is engaged.
