Right-hand motion control shown
1. Torque the locknut to 23 N-m (17 ft-lb). The bolt must
protrude past the end of the locknut after torquing.
2. Most resistance (firmest feel)
3. Damper
4. Medium resistance (medium feel)
5. Least resistance (softest feel)
Adjusting the Motion-Control
Neutral-Lock Pivot
The flanged nut can be adjusted to obtain a more desired
motion-control lever resistance when moving it to the
neutral-lock position. See
1. Loosen the jam nut.
2. Tighten or loosen the flanged nut to the desired feel.
For more resistance, tighten the flanged nut.
For less resistance, loosen the flanged nut
3. Tighten the jam nut.

Maintenance
Servicing the Hydraulic
System
Hydraulic Oil Type: Toro
or Mobil ® 1 15W-50.
Important: Use oil specified. Other fluids could cause
system damage.
Each Hydraulic System Oil Capacity: 1.5 L (1.59 US qt)
per side with filter change
Checking the Hydraulic Oil
Service Interval: Every 50 hours—Check the hydraulic oil
level.
1. Position the machine on a level surface.
2. Disengage the PTO, move the motion-control levers to
the neutral-locked position and set the parking brake.
3. Stop the engine, remove the key, and wait for all moving
parts to stop before leaving the operating position.
4. Allow the engine and the hydraulic system to cool for
10 minutes.
Note: The oil level on the dipstick will be incorrect if
the oil is checked when the machine is hot.
5. Move the seat forward.
6. Clean the area around the dipsticks of the
hydraulic-system reservoirs
7. Remove one dipstick from the hydraulic reservoir
(Figure 82).
8. Wipe the dipstick off and thread the dipstick into the
reservoir.
9. Remove the dipstick and look at the end
If the oil level is at the add mark , slowly pour only
enough oil into the hydraulic reservoir to raise the level
to the full or H line.
Important: Do not overfill the hydraulic units
with oil as damage may occur. Do not run the
machine with the oil below the add mark.
10. Install the dipstick.
11. Repeat procedure for the opposite dipstick.
