Mahindra 4550/4540 Tractor Bad PTO Safety Switch

Overview

A hands-on repair walkthrough showing how to diagnose and replace a failed PTO safety switch on a Mahindra tractor. The owner shares continuity testing with a voltmeter, the part number (00001305P04), a price comparison (dealer at $128 vs. roughly $10-11 on eBay), and an honest account of a wiring puzzle he couldn't fully explain but solved. Best for Mahindra owners facing a no-start condition traced to this switch.
