Hello,
An electric circuit diagram would be needed for this machine and possibly mechanics service book. Kubota to an engine there is an instruction.
It was brought to repair the machine, 1 year of somebody took it to pieces
taking the engine, the cylinder head off, the pistons getting rusty, his winter with mud all of it. Is cable burned, so yet anything possible.
I try to look for service books because of this to it.
best regards, Laci
