Will this fit your machine?

Check your attachment model and serial number, then compare the old gearbox mounting holes and shaft layout with our photos. If your 33 tiller has serial number 8929 or lower, or your 49 snow thrower has serial number 9275 or lower, message us before ordering. These early attachments used a different housing, so we need to check the mounting pattern with you.

Check before you order

Match the attachment model/serial, original gearbox, mounting holes and shaft layout. For 33 tiller serial 8929 or lower, or 49 snow thrower serial 9275 or lower, contact FLIP before ordering: these early attachments used a different housing.

Application details

AM133890 identifies the gearbox assembly; AM34013 the gear case; AM34014 an older housing. Match the original assembly and mounting pattern rather than assuming every housing number identifies the complete supplied gearbox.

Before installation

Follow the attachment service manual for installation and lubricant type/amount. Check lubricant fill before first use.
