Once the generator was mounted, I hooked up the generator leads to the load box, and grounded everything, and I mean everything:
Engine to frame by bonded loop
Frame to ground
Generator to ground
Load box to ground
Generator Control Box to ground
I also got longer pto shafting, measured carefully, and then drilled a hole through the wall so I can park my tractor outside and generate power by PTO.
I was glad when all this was done because my house had been without back up power for (2) days, and it was pretty windy. Now, at least I have back up power, and with my new Generator Load Box, it will be much better power now that I can set it to match grid-power quality.
Here is a picture of the generator with its new mounting frame, and all hardwired in to my home's main power.
