#1 in the link shown below is a neutral start relay, has it been checked? Keyswitch has to close this relay, for voltage to go to the starter.

Ok, do you have voltage from the key to the relay?

Customer reply replied 3 months ago
I can here relay click
Mechanic: Curtis B., Technician replied 3 months ago

OK, is there any output from the relay? If there is, try a wire direct from the relay to the starter solenoid switch terminal.

The dealer gave me that re170320 but I don't find it on tractor
Mechanic: Curtis B., Technician replied 3 months ago

Does the key switch wire send any voltage to the solenoid? If it does, try a larger size wire from switch to solenoid.
