Here is a link to the parts catalog:
Bobcat Parts Catalog - Find Diagrams for Your Equipment - Bobcat Company
Locate all parts and component information about your Bobcat equipment with detailed visual diagrams and illustrations with parts numbers and add to your list.partscatalog.bobcat.com
You should be able to find the auxiliary components and where the spool is on the control valve.
I do see that at some point they were listed as an option so your machine may not be set up for them.
