I have an L3901 with less than 300 hours, and just the other day I got two error codes, E93 & E94. Does anyone know what this means and how I can rectify it? Thank you in advance!

Thanks, but where do I find the "Starter Relay"?
under the rear bonnet, near the top left hand side of the instrument cluster.
super easy to see when you pull the instrument cluster and steering wheel.
starter relay and engine relay should be same same.
follow wiring color at the relay back to the starter and you can help make sure you be looking at the right stuff.

It's more likely a low battery issue.
Turn everything off, pull the battery and have it load tested.

Thank you so much for your assistance. It's going to be -20° here for the next few days and my tractor is not in a shed, so I'll have to wait until it's a bit warmer out. But for now, at least there's no snow in the forecast so I don't have to worry about doing any plowing. Thanks again! I appreciate it.

Thanks Wolfman. I think I'll try your remedy first before I do the step above that was recommended. It's going to be -20° here for the next few days and I'd rather pull the battery and see if that works. I appreciate your help!
