Brand: CNH
Model: ST250 Tiger-Mate 255 Field Cultivator
Part No: 90377492
Date: October 2020
Type of Document: Assembly Instructions
$ 55
This field cultivator spends its life in rough ground conditions—seedbed prep, weed control, and leveling ahead of the planter. These assembly instructions are what I’d use when putting an ST250 Tiger-Mate 255 together correctly the first time, or when I’ve got one that was poorly set up from the dealer. If a wing won’t fold square or a shank bar doesn’t sit level, this document helps me trace the issue back to how it was assembled, then realign and tighten everything the way CNH intended.
Applications & Use Cases
FAQ
Q: Can I use this manual on a tablet out in the yard?
A: Yes, it’s handy on a tablet so you can zoom in on diagrams while you’re standing at the machine.
Q: Is it worth printing parts of this manual?
A: I’d print the main assembly views and keep them in a sleeve by the workbench to avoid greasy fingerprints on your device.
Safety Note
Always secure the cultivator and support raised sections mechanically before working underneath or loosening any components.
