Yes. Sorry to the thread.
I used same dealer. They changed more releif valves, put gauges on and adjusted adjustable releif valves to maximum pressure. Bottom line, it runs and works good but this little machine suffers from heat. I have not used it much for my business because I have gotten very busy and started sub contracting the digging. So no long digs with it since last dealer trip. I just use it for mixing feed/mineral in front bucket for cows. It's perfect for that. I think I will go back to full size backhoe for work.
Darn. Well, I'm sorry to hear that's the upshot but sure do thank you for the update. One last question or two... Do you think yours is any different from other M59s? Or is what you are seeing just the limitation of the model?
And you've made me wonder if the backhoe temperature limitation is nothing more than the size of the oil cooling radiator?? The Kubota radiator looks big enough physically, but I also know that as an engineer I've watched in amazement for 40 years now as one foreign manufacturer after another repeats the same mistake on machines built for export to the US. Each one seems to have to learn all by themselves that they need to increase the cooling capacity on machines they send over here. I'm not exactly sure as to why.
Anyway, I've already said that I never have considered our M59 to be a real commercial/industrial duty TBL in the same league as the various makes of yellow industrial Cases, Cats, Fords, and JDs we see everyday on job sites. Frankly, I looked for one of those makes in the under 70hp & less than 9000 lbs. size and couldn't find it. Apparently nobody but Kubota & JD builds one. Naturally enough, the Kubota isn't built like a Case or Cat. For that matter, it isn't as quiet either. But all and all it is a better compromise for my work. It sure is a more handy machine with plenty of power and speed for my non-commercial uses. I can't help wondering if the differences between M59s we keep running into are nothing more than all of us us using the machines to nearly their full capacity in a different type of ground? Around here in the Rockies, I find myself needing the M59's strength and handy small size more than it's cycle speed. So I work mine hard, but get to run it at fairly low RPM. Or maybe that's just a difference in the jobs.
Good Luck,
