Q. Where is the serial number for my machine?
A. The serial number for your attachment is stamped next to the mounting rail on the discharge side of the

Q. Where do I find replacement parts?
A. First check your local equipment dealer and if they do not have the parts, ask them to order from the
BrushHound factory.
Q. How often should I change my knives?

after it seems ready to use before resuming operation.

Q. How can I prevent my hydraulic hoses from coming off during operation?
