I have a B7510 HSD that will not crank. The lights on the dash comes on but the engine will not crank. I crossed over the two terminals on the starter and the starter runs but will not engage. I bypassed the two safety switches under the seat. I made sure the lift leaver is centered, the PTO is disengaged and put the transmission in neutral.
The tractor started just fine and I allowed it to run while I put some tools in the bucket. When I got back on the tractor my knee hit the ignition switch and shut down and has not started since.
I am looking for suggestions on what to do next.
Thank you for any help you can give me.

To jump the starter you don't jump the 2 large terminals.
You jump from the large terminal to the small terminal to engage the solenoid with will then power the starter.

Check all fuses

Double check the HST pedal, turn the key to crank then wiggle the HST pedal.
Also Engage and disengage the PTO lever.

If none of that works, if you hit the key and switch just right you might have damaged it, you will need to test it.

It turns out one of the fuses was blown. Thanks for the help.
I found a wire to the safety switches had the insulation worn off and repaired it. Hopefully it solved the issue.
