LS XR4046
Posted this in repairs, but it's probably better out here. Didn't realize there was an LS forum when I originally posted.

Dumb question I'm sure, but bear with me. I'm new to tractors. Have an LS XR4046. Battery appears to be dead (slow.to start over winter, jumped it off a couple of times, now nothing when I crank).

Are there any guides with pictures on removing the battery on this model? It is underneath a.solid plate and.has several hoses running through and around. I don't see a straightforward removal. Sent my father in law a picture (he's been driving Kubota for decades) and said his is not "protected" like mine. Any help appreciated. Have pasture that needs mowing:)

Attach a picture. Mine just has a hold-down & pretty simple.

Your tractor is very similar to mine. Check out this video I made when I replaced my battery. Hope it helps

Hey! I actually saw your video before I came here! Your battery "area" looks a bit different than mine. Attaching some pictures. I removed the circled bolt on each side. The top plate (for lack of a better word) that says "avoid direct water spray on ECU" still doesn't move, though...it seems.to be connected.to a vertical metal piece behind the battery (circled in blue).

I'm probably missing something super easy here. I'm new to tractors and am probably going to start hanging out here more .need.to learn more about how to work on/take care of what I've got.

First thing you need to do is clean the area, especially your radiators. Those fins look plugged. Cleaning the area will help you (and us) identify things a bit better.

Your ECU is mounted on top of your battery. No worries. The bolt you circled, and the one on the other side, looks like it acts as both the mount for the ECU and the battery hold down. Remove both those bolts. Its okay to disconnect plugs from the ECU to get it out of the way. Just make sure you plug it back in correctly and keep moisture from entering the plugs (don't do this on a rainy day outside). Once the ECU and mount is out of the way, it should be simple enough to pull the battery.

trickle charge the battery overnight and clean your negative and ground points.

Be sure you're not wasting your money and time. Batteries last pretty long if you maintain them.

I'll hook mine up to a battery charger that auto switches to "maintain" mode after the battery charges up then I let it hooked up overnight.

If you battery is dead it won't ever switch to maintain mode and you know its dead.

Often it is just a bad connection on one of the main wires to the battery, check ground(& frame ground from battery) and hot.

Agreed it needs to be cleaned. Attaching another picture. The ECU has a nut that appears to hold it in place where the arrow is pointing (close up circled). It's stuck on there pretty good. Assuming that's going to have to get loosened and removed before I can take the ECU off.

You should be able to loosen that nut & maybe one on the other side & rotate the whole ECU/plate assembly up & out of the way. Also looks like you have a foot hold down at the bottom front near side of the battery Still covered in dirt & leaves/clippings. remove the bolt & plastic foot & with the cables disconnected, the battery should slide forward & be removable by tipping/rotating/finding clearance.

Thanks all. Was able to get it out today. Had to find a smaller socket to maneuver in to get to the nut to get the ECU off.

New question now. When I pulled the battery out, I noticed a cable (pictures) that as best I can tell wasn't attached anywhere. I'm about to go do some research, but can anyone tell me what this cable is? Is it something I didn't see attached to the ECU Somewhere or was.it truly just sitting loose back there behind the battery? It's yellow if that matters.

That doesn't look factory. I'm assuming you didn't purchase this tractor new? Can you follow the wire and see where it goes?

I did not buy it new. Bought it about a year and a half ago. One previous owner. Had ~400 hours when I got it. I didn't think it looked like it came off of anything I have disassembled. I'll see if I can trace it a ways and find out where it goes.

Also, really appreciate your help on this. I"m obviously new to this sort of stuff. Are there any good youtube resources for basic tractor maintenance type work just to familiarize myself with how to do the basics of maintenance and care?

Honestly, you're in the right place for that kind of thing, especially tractor specific. The folks here are a huge wealth of knowledge and most are eager to help. However, if you're looking for videos specifically, obviously check out mine (but I don't really do "how-to" videos), check out channels like Tractor Time with Tim, Tractor Mike, Messicks has a good how-to list, probably a few others. Its been a while since I've watched other content creators as I am busy with my own projects.

Asking a question like that on this forum will generate a huge response. In fact this question was asked on here a while back.

Thanks!

To end the saga here, I got the battery out. Got a new one from AutoZone, and am back up and running.

Now that I've found this place, I'd guess I'll be around more trying to learn. Thanks everyone!

A secondary ground cable? Any high draw after-market electric stuff installed? if you can't trace out that wire, check for continuity to the frame (or a bolt) to see if it is a ground.

Morning, I have an XR4046 and am probably going to replace the battery. Which new battery did you install in your 4046? Looking at LS's online parts listing, it shows the following: BATTERY-MF-TRG740.
