They are so cool.. Mine came with a roto tiller. I did not know there was a backhoe attachment. If its ok tomorrow i will measure the fuel filter and if you have a spare in stock and measure yours if its the same maybe i can get a part number from you so i can order some. Found some close but not totally correct. After moving here and realizing how handy a hoe would be i bought a used IHI 15NX. another great machine from Japan powered by Yanmar 3 cyl almost the same as the 7100 Kubota motor

Me too: PTO 42" tiller, rear blade, cultivator (tines).

I looked for a the backhoe for years. Its model B670 complete with the adapter brackets for the axle housing. The hoe is powered off pump via the PTO. The BH's front brackets attach to the crossmember of the loader. If you don't have the factory loader you'll find or have to make a crossmember.

The fuel filter in the clear holder I use is a Wix 33389 from NAPA.

My major complaint is that it seems to always want to regen just as I drive up to the barn at the end of the day. So either I find stuff to do, let sit and regen or cancel the regen. I do not like to cancel it. So if you see me hauling rock after dark it is just to be doing something while the tractor burns extra fuel to put all the pollution out in 15 minutes all at once instead of a little all the time.

That seems to happen to me more often than not too. I do not cancel the burn because I've been told it can cause problems by the NH dealer who sold me my used 2015 workmaster 33 a few years ago. No problems so far.

I have a 2019 Kubota M70/60 equipped with DPF. The regen light would come on every 10-12 hrs of operation. If mowing or baling, no problem because you have the revs up for a prolonged period and you can keep working interrupted with no issues. However, that pesky light can come on just when you are ready to put the tractor away or are doing low rev operations like loading. Then you may have to sideline the tractor, put the revs up and wait. Last year I was buying antigel for my tractors and grabbed what I thought was two qt bottles of Lucas antigel when one was actually Lucas injector cleaner and upper cyl lube. Rather than return it I added the cleaner to my fuel. Twenty hrs later the regen light had not come on leading me to think it broke. I've been using this product since last November and it has doubled the time in between regen cycles. You might want to give it a try.

Thats interesting. I'm getting a Kubota with DPF and may try that.

Gear down and run 1500 rpms even doing loader work. It can't be run like the older tractors and is not designed to be. I read the manual and now go many months without a regen cycle. It is very rare to hit regen unless I idle some while off the tractor.

I think the higher rpm maintains a better oil pressure also. I never let my diesels idle.

It really does depend on the (diesel) engine and the application. How many diesel rigs at a truck stop (higher) idle for the night with no problem? On my old Kubota I'm inclined to let it idle for a bit vs frequent use of the battery and starter, esp considering its 'dynamo' generator to keep the battery up for frequent restarts. And I really dislike higher no-load operation of a diesel. What a waste. A higher RPM under load in the torque range is a diesel's happy space.

As far as oil pressure, if you have an old, loose diesel and lug it at low RPM... well, that is NOT it happy place. You are not wrong but you should do that.

One thing I've heard time and again is a diesel genset running at 1800 or 3600 with no or very little load is bad JuJu.
