Engine
• Engine Specifications: See your Engine Owner's
Manual
• Engine Oil Type: Exmark Premium Engine Oil
is recommended.
If using an alternative, use high-quality, low-ash
engine oil that meets or exceeds the following
specifications:
– API service category CJ-4 or higher
– ACEA service category E6
– JASO service category DH-2
Important: Using engine oil other than API
CJ-4 or higher, ACEA E6, or JASO DH-2 may
cause the diesel particulate filter to plug or
cause engine damage.
Use the following engine oil viscosity grade:
– SAE 10W-30 or 5W-30 (all temperatures)
– SAE 15W-40 (above 0°F)
• RPM:
– 3TNV80FT: 2600 ±50 RPM (PTO not
engaged) Idle: 1400 ±50 RPM
– 3TNV88C: 3000 ±50 RPM (PTO not
engaged) Idle: 1400 ±50 RPM
Fuel System
• Capacity: 12 gal. (45.4 L)
• Fuel Recommendations:
– General Notes:
◊ Never use kerosene or gasoline instead of
diesel fuel.
◊ Never mix kerosene or used engine oil
with the diesel fuel.
◊ Never keep fuel in containers with zinc
plating on the inside.
◊ Do not use fuel additives.
◊ Use only clean, fresh diesel fuel or
biodiesel fuels.
◊ Purchase fuel in quantities that can be used
within 180 days to ensure fuel freshness.
– Petroleum Diesel
Cetane rating: 45 or higher
Sulfur content: Ultra-low sulfur (<15 ppm)
Diesel Fuel Specification:
◊ ASTM D975
◊ No. 1-D S15
◊ No. 2-D S15
Use summer-grade diesel fuel (No. 2-D)
at temperatures above -7°C (20°F) and
winter-grade fuel (No. 1-D or No. 1-D/2-D
blend) below that temperature.
Note: Use of winter-grade fuel at lower
temperatures provides lower flash point and
cold flow characteristics which eases starting
and reduces fuel filter plugging.
Using summer-grade fuel above -7°C (20°F)
contributes toward longer fuel pump life and
increased power compared to winter-grade
fuel.
– Biodiesel
This machine can also use a biodiesel blended
fuel of up to B20 (20% biodiesel, 80%
petroleum diesel).
Sulfur content: Ultra-low sulfur (<15 ppm)
Biodiesel fuel specification: ASTM D6751
or EN14214
Blended fuel specification: ASTM D975,
EN590, or JIS K2204
Important: The petroleum diesel portion
must be ultra-low sulfur.
Observe the following precautions:
◊ Biodiesel blends may damage painted
surfaces.
◊ Use B5 (biodiesel content of 5%) or lesser
blends in cold weather.
◊ Monitor seals, hoses, gaskets in contact
with fuel as they may be degraded over
time.
◊ Fuel filter plugging may be expected for a
time after converting to biodiesel blends.
◊ Contact your Authorized Exmark
Distributor if you wish for more
information on biodiesel.
