This Warranty Does NOT Cover Failures
Caused By:
Abusive operation
Natural calamities
Unauthorized modifications
Improper repairs
Use of non-Genuine Kubota parts
Neglected maintenance/incorrect
operation (specified in Operatorç—´ Manual)
Unapproved attachments
Usage which is contrary to the intended
purpose
That has to be the most vague disclaimer I've ever seen (I read the entire warranty PDF btw., and that is the only mention and it's really not a fast rule but a hold harmless for Kubota so they can determine if the failure was caused by abuse or not..... I abuse my units all the time, that is what they are for....
So tell me what is considered an 'unapproved attachment??? It's still phooey. From day one I've used 'attachments from New Holland, John Deere, Geihl and other manufacturers. Thats the way farming is. Besides, Kubota don't produce the 'attachments' I need or use and if they did, I'd probably not have them anyway.
But then, I don't run sub compact tractors. The little tractors would fit nicely in the bucket of either my M9 or 105X. The 105 can pick up a Chevy 1/2 ton 4x4. I've done that before.
Kinda reminds me of the 'You must use Kubota fluids and filters or it voids your warranty... thats big phooey as well. Neither of my units, except for the initial fluid fills from the factory have ever seen any Kubota fluids. I will say I use Kubota filters because Messicks sells them at competitive to Fleet Guard prices but fluid wise, nope.
Years and years and years ago, probably before you even knew what a Kubota was and long before this forum even existed, I had a 16 horse pto Kubota with a Kubota branded 3ph mount backhoe that I sold. I never had issue one with it either. Mounted on the Cat 1 lift arms with a top mount torque link and PTO driven pump....right from Kubota.
Your warranty blurb leaves a whole bunch of intrepretation latitude, a whole bunch. I have a bit more invested than most on here in power units and I've never had a qualm about using them. I believe I use my units much harder than and CUT owner would... and I have ho issues with either, except maybe tires but thats because I do tillage with them so slippage in FWA is commonplace.
They ain't garage queens....
