Hi. I have a cub cadet 1525. When I start the mower for the first time and engage the blades, it works fine. Once the mower gets warm, if I disengage the blades, it will not re-engage until I turn mower off and allow it to cool for 10 minutes. I had an issue a while back with it not engaging. I replaced the relay and it fixed the problem. I replaced the relay this time and it did not fix the problem. Any suggestions?
