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 6.3 and Engine Manual for specific
maintenance intervals.
If the injection pump, injectors or the fuel system require
service, contact an authorized Jacobsen Dealer.
Gasoline Engine:
1. Drive modestly for the first 25 hours at reduced engine
speed.
2. Avoid full throttle starts and rapid acceleration.
3. Allow the engine to reach operating temperature before
operating at full load.
4. Change the oil and filter after the first 8 hours of
operation.
5. Refer to Section 6.3 and Engine Manual for specific
maintenance intervals.

disengage all drives, lower implements to the ground,
engage parking brake, stop engine and remove key from
