1.1 OPERATING SAFETY ______________________________________________________
1. Safety is dependent upon the awareness, concern and
prudence of those who operate or service the equip-
ment. Never allow minors to operate any equipment.
2. It is your responsibility to read this manual and all
publications associated with this equipment (Safety
and operation manual, engine manual, accessories
and attachments). If the operator can not read English
it is the owner’s responsibility to explain the material
contained in this manual to them.
3. Learn the proper use of the machine, the location and
purpose of all the controls and gauges before you
operate the equipment. Working with unfamiliar
equipment can lead to accidents.
4. Never allow anyone to operate or service the machine
or its attachments without proper training and
instructions; or while under the influence of alcohol or
drugs.
5. Wear all the necessary protective clothing and
personal safety devices to protect your head, eyes,
ears hands and feet. Operate the machine only in
daylight or in good artificial light.
6. Evaluate the terrain to determine what accessories and
attachments are needed to properly and safely perform
the job. Only use accessories and attachments
approved by Jacobsen.
7. Stay alert for holes in the terrain and other hidden
hazards.
8. Inspect the area where the equipment will be used.
Pick up all the debris you can find before operating.
Beware of overhead obstructions (low tree limbs,

4.2 ENGINE _________________________________________________________________
IMPORTANT: A separate Engine Manual, prepared by
the engine manufacturer, is supplied with this tractor.
Read the engine manual carefully until you are familiar
with the operation and maintenance of the engine.
Proper attention to the engine manufacturer’s
directions will assure maximum service life of the
engine. To order replacement engine manuals contact
the engine manufacturer.
The proper break-in of a new engine can make a
considerable difference to the performance and life of the
engine.
Note: The tractor is designed to operate and cut most
efficiently at the preset governor setting. Do not change the
engine governor settings or overspeed the engine.
During the break-in period, Jacobsen recommends the
following:
Diesel Engine:
1. During the first 50 hours of operation, a new engine
should be allowed to reach an operating temperature of
at least 140°F (60°C) prior to operation at full load.
2. Check the engine oil level twice daily during the first 50
hours of operation. Higher than normal oil consumption
is not uncommon during the initial break-in period.
3. Change engine oil and oil filter element after first 50
hours of operation.
4. Check and adjust fan and alternator belts.
5. Refer to Section 5 and Engine Manual for specific
maintenance intervals.
If the injection pump, injectors or the fuel system require
service, contact an authorized Jacobsen Dealer.
