Installing an Attachment
Important:
Use only Toro-approved attachments.
Attachments can change the stability and the
operating characteristics of the traction unit. The
warranty of the traction unit may be voided if used
with unapproved attachments.
Important:
Before installing the attachment,
ensure that the mount plates are free of any dirt or
debris and that the pins rotate freely. If the pins do
not rotate freely, grease them.
1. Position the attachment on a level surface with
enough space behind it to accommodate the
traction unit.
2. Start the engine.
3. Tilt the attachment mount plate forward.
4. Position mount plate into the upper lip of the
attachment receiver plate (Figure 22).

5. Raise the loader arms while tilting back the mount
plate at the same time.
Important:
The attachment should be raised
enough to clear the ground, and the mount
plate should be tilted all the way back.
6. Stop the engine.
7. Engage the quick attach pins, ensuring that they are
fully seated in the mount plate (Figure 23).
Important:
If the pins do not rotate to the
engaged position, the mount plate is not
fully aligned with the holes in the attachment
receiver plate. Check the receiver plate and
clean it if necessary.

If you do not fully seat the quick attach pins
through the attachment mount plate, the
attachment could fall off of the traction unit,
crushing you or bystanders.
Ensure that your quick attach pins are fully
seated in the attachment mount plate.
Connecting the Hydraulic Hoses
If the attachment requires hydraulics for operation,
connect the hydraulic hoses as follows:
1. Stop the engine.
2. Move the auxiliary hydraulics lever forward,
backward, and back to neutral to relieve pressure
at the hydraulic couplers.
3. Move the auxiliary hydraulics lever into the reverse
position.
4. Remove the protective covers from the hydraulic
couplers on the traction unit.
5. Ensure that all foreign matter is cleaned from the
hydraulic connectors.
