And then there was a 310...

I prefer the separate ground as well. The lights are aftermarket up on the cab, so they're set up with 2 wires already. Running a ground line around will be simple enough when it dries out.

There are a lot of loose, or missing bolts holding the cab on/together. That's not the ground path, but it speaks to condition I guess. That's going to be a whole other thing, getting the cab to stop rattling... All the parts breakouts tend to show items in isolation, rather than part of an assembly. Only a couple of them have ghost images of their surroundings so you know how things relate. They're very nice drawings as is, but a little context would help in many cases.

I watched a video of someone working on a 410 last night. Deere went with a pretty complicated hydraulic system compared to what Case did. High, Intermediate, Low, and Tank pressure zones in the system, variable displacement pump that is demand controlled. I've got the full tech manual, so I am beginning to understand it. Supposedly, it is a very smooth running system that will handle multiple demands at once without dropping flow anywhere with no issue, but it became complex as a result.

And now I've got the "Getting to know you" song running loops in my head... Thanks... I did that musical just a few too many times over the years I was in the arts...

Sorry about that. Although I suppose there are worse ear worm songs you could have stuck in there!

Managed to get a few more things sorted out...

New seat bottom arrived. Much nicer than the chewed up remains that it came with...
I'd like to replace the back unit too, but it isn't completely gone yet. I do need to make some support brackets that are missing, but they're the same on the JD300, so I have something to work from.

The parts came in to finish up the wiring for the heater's blower.

Also managed to get the regular 6" fan running for ventilation. Don't know how long that one will hold out, but I'll keep working some oil back in the bearings...

Got the new wiper, and arm installed. I need to change the angle a little, but it's ok for the moment.

While I was up there, I pulled the front work light apart. There's a reason they're dim... 17 watt, 28 volt bulbs. Obviously they have to go... I had one 20 something watt 12v on the shelf. Far brighter, but that's never going to be of any use. I expect I'll just end up replacing all the fixtures with LED units. I can get some hot LED's to put in what I have, but they cost as much as a complete fixture, and I have to replace the crushed one anyhow... That will come together when I do some of the re-wiring. I'll be putting some big LED's in place that will draw more than the existing, and the current wire isn't going to be up to it. Probably have to make a relay bank with diodes to make the 3 lighting options work. I also found where the wire is supposed to be for the loader tower mounted lights. They're all MIA. I ordered a few 100' rolls of different color wire as this is turning in to a complete rework... Of course, I'm doing all this because I can't do much else with missing hydraulic lines... The odds of me using the lights is pretty slim. I've used the lights on the other tractors only a handful of times my entire life.

Pulled the floor panel over the battery. Going to need to do something there... Battery is just sitting on a shelf, loose. The parts machine is a bit older, and has more of a box setup. Strangely, sitting on the shelf in the barn is the kit with the hold down hooks for the earlier setup. I thought perhaps they were from the JD300 we've had for years, but I don't think so, and that's the only Deere we've had... Strange.
