KNIFE REPLACEMENT:

Triumph rock guards use bolt-on ledger plates. It is not necessary to remove the guards from

the cutterbar. Follow this simple procedure to remove the ledgers. (Remove the knife from the

mower first.)

1. Raise the cutterbar 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

necessary 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 contact 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-cutterbar attaching bolt.
