Annual Inspection
To ensure efficient operation and long life of your
mower, the following checks and maintenance
should be carried out before storing the equipment
at the end of the mowing season:
1. Perform all services outlined in the section on
periodic maintenance.
2. Check jackshaft coupling to ensure that keys
are in place and bolts are fully tightened.
3. Check that all split taper bushings are secure.
4. Check transport locks and springs for correct
operation. Replace broken, damaged or worn
components.
5. Check that all mowing unit tie rods are secure
and properly adjusted:
a. Set mower level on a flat surface, with
center line of front and rear jackshafts the
same height above ground level.
b. Use a string arrangement as shown in the
diagram on the next page to check the
alignment of the mowing units.
6. Wipe exposed cutting edges of bed knives and
cylinder blades with light oil to prevent rusting.
7. Check that all safety guards are intact and se-
curely fastened.
8. Jack up carriage frame. Remove the wheel
hubs, clean and inspect the bearings and pack
the cavity between the bearings with 3.2 cubic
inches of good quality general purpose grease
(such as Mystick JT-6 High-Temp NLGI No. 2,
or equivalent). Adjust the bearings so that
there is no end play but the wheel turns freely.
DO NOT OVERTIGHTEN THE BEARINGS.
9. Check the rubber bumpers on the outer mow-
ing unit lift stops. Replace worn or damaged
bumpers.
