The PO may have had the brake safety switch unhooked for that reason. It may be keeping the motor from starting if the switch is bad. If so I would replace the switch. And also as stated the PTO switch has a safety included to not allow the motor to start if the switch were to be in the engaged position. You will probably need to replace the PTO switch with a new one. As said our sponsors should have what you need. And these diesels are notorious for hard starting with the small garden tractor batteries, but it can be done. You need to find the largest CCA battery and put it in there. Also there is a glow plug upgrade that can be done to help cut down on the draw from the battery and also as mentioned, there is a high torque starter that can be upgraded to, with a bit of work. The only mod I have on my BRS is the glow plug mod and heavy gauge wires for the ground from the battery and for the positive wires. Factory size is just a bit small. I'll see if I can round up the starter and glow plug mod write ups for you. Even with these few things that need attention, you got an "awesome" Cub. Way to go.
