IV) Knife Maintenance
Since the EX Series is designed to finely mulch wood with relatively low horsepower, it is critical that
the knives are present and that they be kept sharp to keep cutting efficiency at a maximum. The standard
cutting tool is a hardened steel knife with multiple cutting surfaces, allowing it to be either sharpened, or re-
placed depending on the circumstances .
a) Sharpening
When sharpening tools are available, the knives can be sharpened using a grinder. Simply run the
grinder in plane with the flat cutting surface of the knife.
a) Replacing
The final option is replacement, simply unbolt the triple knife configuration from the hanging ear on
the cutter drum and replace it with a new set. Retighten with the same hardware previously used, unless the
hardware is damaged or not in good working condition.
V) Cleaning Your Attachment
Cleaning your Attachment regularly will help prolong the life of both the paint and the safety decals as
well as minimize the risk of unintentional fire.
1) Check for excessive grease in the bearing areas, cleaning off any excess found.
2) Clear debris from the hydraulic hose area, bearing area or any other area that may experience excessive
heat.
3) Clean the inside and top of the Attachment with a pressure washer, removing any accumulated mud,
grass or other debris. Keep in mind that mud build up on the cutter drum can cause imbalance.
4) Touch up paint where needed as this will help prevent your Attachment from rusting.
VI) Optional Mounts
Your Attachment comes with a mount custom made to fit your Power Unit, but additional mounts
may be purchased to put your Attachment on more than one Power Unit. Mounts are connected to the
Attachment by 4 provided 1” bolts, simply line up the holes on the mount with the corresponding holes on
the Attachment, insert the bolts and secure with the provided nuts and washers. Check with your local Brush
hound Dealer before changing Power Units to verify compatibility.
