MAINTENANCE
LEDGER PLATES
Triumph rock guards use bolt-on ledger plates. It is not necessary to remove the guards from the cutter bar.
Follow this simple procedure to remove the ledgers. (Remove the knife from the mower first.)
1. Raise the cutter bar off the ground and block up.
2. Using a punch, drive the bolt from the head end thru the guard. The head will shear off. It is not nec-
essary to remove the nut.
3. Scrape all dirt from the mating face of the guard.
4. Snap in the new ledger and tighten the new bolt and nut. Make sure the ledger is down TIGHT in con-
tact on its bottom face.
5. Stake over or flatten the bolt on the nut side to make sure it does not become loose.
6. Check and tighten the guard-cutter bar attaching bolt.
Inner and outer shoe ledger plates are attached with rivets. These ledgers can also be replaced without
removing the shoe.
1. Shear off the old rivets by a sharp blow with a hammer at the edge of the plate.
2. Scrape dirt off the shoe mating face.
3. Install new ledger plate and rivets. Make sure they are TIGHT.
ATTENTION: Loose ledger plates can cause poor cutting and destroy otherwise usable knives, guards, and
shoes. KEEP LEDGERS TIGHT.
Cylinder Rod Maintenance
It is important to visually inspect the hydraulic cylinder rods daily before use. It is highly recommended that
while the machine is stored or getting very little use that a protectant is applied to the hydraulic cylinder rods to
prevent degradation. If the machine receives more frequent use, be sure to fully cycle each cylinder function so
that the cylinder rod is coated by the systems hydraulic fluid. Depending on your operating environment it may
be necessary, under normal operating conditions, to apply a protective lubricant to the cylinder rods for
protection against rust and pitting. Hydraulic fluid may provide a suitable amount of protection, but remember
any protectant can attract dust and debris so attention must be given to the cylinder rods daily. Also remember
that any other protectant must be compatible with hydraulic fluid. Alamo Industrial is not responsible for rust or
pitting of the cylinder rod due to weather exposure or impacts from normal operation or mounting. If hydraulic
cylinders and or the cylinder rods are damaged as a result of the rods rusting or pitting, the hydraulic cylinders
and rods will not be covered under warranty by Alamo Industrial.
