CNH REAR RIPPER Installation Instructions (90386697)

Out in the dirt, this rear ripper’s working in hard-packed soil, roots, maybe old gravel drives—stuff that’ll shake anything that’s not mounted right. This installation manual walks you through how to hang the CNH rear ripper on the machine so it’s aligned, secure, and actually tracks straight behind you. Say you’ve just bought a used ripper kit off an auction; with this, you can trace the mounting points, route the hoses where they won’t get pinched, and verify the frame’s square before you ever drop the shanks in the ground.

Applications & Use Cases

• Install a new or used ripper kit by following the step order, so you don’t have to guess which bracket or pin goes on first.
• Check an existing install when something looks off; you can inspect each mount and test fit to isolate where it was done wrong.
• Route and secure hydraulics the way CNH intended, so hoses don’t rub, kink, or get ripped off when you curl or raise the implement.
• Align the ripper to the tractor frame, then verify clearances so it won’t hit tires, drawbar gear, or PTO shields under load.
• Bleed and test hydraulic functions after hookup, making sure the ripper raises, lowers, and floats like it should.

FAQ

Q: Is this a PDF I can search on my laptop or phone?

A: It’s typically a PDF, so you can search by keyword—handy when you’re trying to find a specific bracket or hose layout.

Q: Can I print just a few pages to take to the shop?

A: Yes, most folks print the key install and torque pages so they can get them greasy without worrying about the whole manual.

Safety Note

Always support the implement with proper stands or a hoist and relieve hydraulic pressure before you get under or behind the ripper during installation.
