International Cub La-Bay Tractor.
Assembled in this manual are operation,
lubrication, and maintenance instructions for
International Cub and Cub Lo-Boy Tractors.
This material has been prepared in detail in
the hope that it will help you to better under-
stand the correct care and efficient operation
of the tractor.
Depending upon your use of the tractor,
these inspections should be performed as
needed, or at least once a year, at which time
a tune-up or other necessary service work
should be performed. Proper pre-season
maintenance will assure you of minimum lost
time when your tractor is most needed.
Your International Harvester dealer has
factory-trained servicemen, modern tools,
and IH service parts to assure you of satisfac-
tory tractor operation. To get the most out of
the t.ractor, and to assure economical opera-
tion and top performance, the tractor should
be inspected periodically by your International
Harvester dealer.
Dealers are kept informed on the latest
methods of servicing tractors. They carry
stocks of IH parts, and are backed in every
case by the full facilitie s of a nearby
International Harve ster district office and
parts depot.
