SECTION 5 - SPECIFICATIONS

DIESEL FUEL
Use a high quality number 1-D or number 2-D diesel fuel as listed in the chart.
Temperature Fuel Cetane
(min)
Sulphur Content
(max)
Below -7°C (20° F) No. 1-D 40* 0.30%
Above -7°C (20° F) No. 2-D 40 0.50%
* When continually operating at low temperatures or high altitude, a minimum cetane of 45 is required. Using
diesel fuel with a sulphur content above 0.5% requires more frequent oil changes, as detailed in the “Engine Oil”
section.
The use of fuel with a sulphur content above 1.3% is not recommended.
NOTE: When long periods of idling or cold weather conditions below 0°C (32°F) are encountered or when
continuously operating at an altitude above 1524 m (5,000 ft.) use number 1-D fuel.
ENGINE COOLANT
Use an engine coolant that contains Propylene Glycol or Ethylene Glycol. Mix with an equal amount of clean
water.
Change coolant every 2400 hours or 24 months (whichever occurs first).
Change coolant filter every 1200 hours or 12 months (whichever occurs first).
NOTE: In order to reduce deposits and corrosion, water used in the cooling system should not exceed
the following limits:
Total hardness 300 parts per million
Chlorides 100 parts per million
Sulphates 100 parts per million
ROAD SPEEDS
The following charts show the road speeds for tractors fitted with 18.4 - 42 rear tires. If the rear tires of your tractor
are of a different size, multiply the road speeds shown in the printed charts by the following conversion factors.
NOTE: For your convenience, a blank chart follows the printed charts so you may insert your own
calculated road speeds.
Tire Size 14.9 - 46 18.4 - 46 20.8 - 38 20.8 - 42 710/70R38
Conversion Factor 0.998 1.056 0.984 1.041 1.032
EXAMPLE:
From the following table with 18.4 - 42 tires - locate the speed for gear ratio F16 at 2100 ERPM - A forward speed
of 29.9 KPH (18.55 MPH) listed.
To calculate the speed with 14.9 x 46 rear tire for the same gear ratio and engine speed use the following
formulas:
29.9 KPH (18.51 MPH) x 0.998 (conversion factor) = 29.9 KPH (18.51 MPH)
NOTE: To determine creeper speeds multiply the ground speed for each gear listed in the ground speed
chart or calculated ground speed by 0.10.
Example: 0.10 x 1.98 KPH (1.23 MPH) = 0.198 kph (0.123 MPH)
