Check Hydraulic Oil Level

Service Interval: Every 40 hours
WARNING
Oil spilled or vented from an overfilled hydraulic
reservoir onto the PTO brake band will cause a
longer stopping time for the deck and blower
rotating components. The deck and blower
rotating components can cause serious injury.
• Wait for all moving parts to come to a
complete stop before servicing.
• Do Not overfill the hydraulic reservoir.
Carefully fill only to the recommended level.
• Replace the brake band if it becomes
contaminated with oil.
1. Stop engine and wait for all moving parts to stop.
Engage parking brake.
2. Wait until the unit cools before checking the
hydraulic oil.
3. Tilt hopper up.
4. Clean area around hydraulic reservoir cap and
remove cap.
5. Wipe the dipstick clean and re-insert the cap back
into the hydro. Lightly tighten the cap.
6. Remove the cap again and check the level of the
oil on the dipstick. See Figure 19 for oil levels.

Note: The oil level on the dipstick will be
incorrect if the oil is checked when the unit is hot.
7. If the dipstick oil level does not register on the
dipstick, add Exmark Premium Hydro Oil. Do
Not overfill.
8. Replace hydraulic reservoir cap and tighten until
snug. Do Not overtighten.

Check Tire Pressures

Service Interval: Every 40 hours
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Check tire pressure in drive tires.
3. Inflate drive tires to 15 psi (103 kPa).
4. The rear caster tire is semi-pneumatic and does
not need to be inflated.
Note: Do Not add any type of tire liner or foam
fill material to the tires. Excessive loads created by
foam filled tires may cause failures to the hydro drive
system, frame, and other components. Foam filling
tires will void the warranty.

Check Condition Of Belts

Service Interval: Every 40 hours
1. Stop engine, wait for all moving parts to stop, and
remove key. Engage parking brake.
2. Tilt hopper up and check pump and PTO drive
belts for wear, cracking, or contamination.
3. Belts are spring tensioned and no adjustment is
necessary unless belts are replaced. See PTO
