It it moves forward, can you get it to where you can get underneath it?
Your going to have to fix the wiring, there's no magical work around.
If you can't go forward you'll have to tow it out backwards, If HST put the range lever in neutral before towing.

Drove the tractor to an accessible location. However clueless on where to start looking for broken wires. Btw tractor is at my property 6 hrs away. Trying to get a clue before i just call a mobile mechanic.. local dealership hasnt been helpful.

I have started to look for more info for you.
The code 91 talks about proportional valve for reverse.

There are a number of models of L5740

If you will advise which model is yours I will try and find location of the proportional valve from parts illustrations.

I have no clue, but I do have a 5740 HST if you need a pic of a certain area or connection or something. I think mine is a 2012 model w/ ROPS, making it a -3 according to Dave's research.

I'm hoping you just ripped out a wire on the brush.

Use the hydraulic filter shown in the following picture to orient you to the reverse proportional valve wiring.
Likely something is pulled apart or off.
