Cub Cadet XT1 LT42E Electric Repair Manual

[lindylex]

I am search for a repair manual for this machine. I found "56 volt electric zero turn troubleshooting guide v1.2.pdf". But this is to new. The machine I have is from 2020. It is one generation older.

Thanks in advance.

Best of luck. Funny, my 2018 Craftsman E150 Electric uses the same control panel. All made by MTD.

Those words are so uplifting. I am so damn stubborn, I will fix this junk and make a video for the world on how to. These machines have so little information on them for repair. Expletives here! This is what I have so far from reading this forum.

Agreed! Reading (sniffing) CANBUS codes is like asking for national secrets. No idea where the port is (if there is one), and how helpful (or not) they can be. That's why I gutted the entire existing system down to the deck motor, the traction motor, controllers, and the battery. Rebuilding from there. I'll build a control panel with a couple of toggle switches.

It is because of your work I am here. This is my issue the machine will not close the contacts when I hit power. I tested the battery with their break out cable and all is fine. When placed in diagnostic mode every switch changes except the brake. It remains "1" never a 0. So I thought that I found the issue. Well I tore the machine down to get to that switch and it is fine. According to the documentation it is the third character from the left.

Looks like you're getting to hate this digital system as much as me.
What is this, "breakout cable"? Is it just for your zero turn mower, or generic?
So you must have a port you can connect to? That's cool!

You've probably tried disconnecting/connecting the battery from the system to perhaps reset it?

Hate, part of a cluster of emotions that lower my vibrations working on this with very little info to work on this equipment. Use this tool to test the batteries.
Diagnostic Harness
Item#: 725P12545

Here is a link to the part, today being [ Sat May 31 12:29:14 PM 2025 ] pretty sure they will remove this link eventually making things even more difficult to repair.

Process, disconnect both batteries from each other and chassis.
Place a multi-meter in the two opening to check voltage on the breakout harness.
Attach this tool to a battery. It has three connections one for ground, power and whatever data the battery sends out.
There is a three way toggle switch on this tool. Set it in the middle and wait for the LED light to go out on the harness.
When the voltage is below 1 volts, set the toggle to position 1 and measure the voltage of the batter. This is suppose to be the Master mode of the battery. If above 24 volts things are looking good so far.
Place toggle switch in the middle. Wait for voltage to drop below 1 volts.
Place toggle switch in position 2. Test voltage in Slave mode. If you receive the same value as above when in toggle position 1 the battery is fine. If below 24 volts the battery has failed.

Do the above test on the other battery they should be very close to the same voltage.

Appreciate that info! Did the harness come with those instructions, or just what you figured out?
So it just checks the battery? What about all the other failure modes?

Anyway, too late for me. Gutted my mower, with only deck motor and traction motor remaining. I'll figure out controllers, and my own control panel with a few toggle switches.

The instruction are from Cub Cadet. Do you know how to put this machine into diagnostic mode? If not this is how you do it. Turn the key on. Hold down the following two buttons RCM and Power button in the middle. The screen switches to "Diagnostic Mode" let go. This is how you check the functionality of the switches. Each position means something "1" means on "0" means off. If they do not change when you change thing. This might provide some direction.
