Case IH 1300 sickle bar mower knife replacement

Appleton WI

New User
Hi,
I'm wondering if anyone can tell me how to replace the knives on a Case IH 1300 sickle bar mower. I have the tool for removing old rivets and put in new ones, but I've never tried it before. Is it possible to remove the entire blade assembly and replace each knife? The knives are so dull that the mower doesn't work well at all.

Any advice would be appreciated.
Thanks,
Dan
 
Take the sickle out and lay the bar on edge on an anvil, sections hanging over the side and strike them with a heavy hammer. It'll shear the old rivets off and you can knock them out of the bar w/ a punch. Those tools don't work too good to remove rivets.

I'd go with bolts when replacing sections. If they hit the hold down clips, change them to the newer style. I've never had a problem switching from rivets to bolts though. They sell a tool that presses the bolts in the bar and then it's really simple to fix when a section breaks in the field.

One other note- The hold down clips need to be snug on the top of the sections and the sections also need to ride on the bottom of the guard or the ledger plates.

Where in Appleton you at? Our farm is on the South side of Kaukauna, on 55 near KK.

Thanks for the help. I greatly appreciate it!

We live on the North section of County JJ, between A and 76. It's technically in Grand Chute, but with an address in Appleton WI. Go figure.
 
I had the same mower as you have. It's cheaper to replace the whole sickle bar than it is to replace the knives and bolts. I always had an extra bar on hand. If I broke a section off of the bar I would just replace the whole bar then replace the missing or broken section when I had time.

If I remember right the cost of the new bar that had all the sections bolted to it was around $65.00 from the CASE IH dealer here in town.
