To The Owner
Y our new I nternational Harvester tractor is design-
ed to meet today's exacting operating require-
ments. The ease and comfort of operation, the
ability to match ground speeds to engine power

ity of the hydraulic system are intended to lighten
your work and shorten your hours on the job.
Your local International Harvester dealer is inter-
ested in the performance you receive from this
tractor. He has factory trained servicemen, inform-
ed in the latest method of servicing tractors, and
modern tools, and original-equipm.ent IH service
parts

ance.
To obtain top performance and assure economical
operation the tractor shou Id be inspected, depend-
ing on its use, periodically, or at least once a year,
'by your International Harvester Dealer.

carefully. It has been prepared to help you operate
and
maintain your tractor with utmost efficiency.
New copies may be ordered from your dealer at
a nominal price.

of parts, always specify the tractor
and engine serial numbers, including prefix and
suffix letters. Write these serial numbers in the
spaces provided below.
