Service the primary drive
1. Check oil level in the gearbox. If necessary, top of
with good quality SAE 90 gear oil (Mobil GX90, Tex-
aco Martak multi gear 90 or equal).
2. Grease PTO shaft universals and check the locking
pins for correct operation.
3. Check belt slack and adjust if necessary.
Tires
Tires should be checked regularly for damage, especially
on units which are frequently transported on highways or
rough roads.
STANDARD TIRES ARE TERRA-TIRES AND ARE
NOT RATED OR SAFE FOR EXTENDED USE
OVER 10 MPH.
Refer to tire inflation chart, page __.
Telescoping Arms
Check operation of telescoping arms by pulling up on
belt. Arms should open and close freely.
Drive Belts
Check condition of drive belts frequently. Replace
damaged or overstretched belts.
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.
