So, long story short, my mechanic didn't want to service mower anymore and brought back my rig partially disassembled. He fixed the bent push-rod and mounted the motor and the rest I had to figure out. SO. I did a small service, new plugs, filters and charged the battery after 7 months of sitting.Now it fires up (with a slight backfire.. I'm thinking old gas..) BUT, to my real question, my brakes no longer lock at the end of the long push that set, what I can only guess, is a parking break? How would you troubleshoot this? I watched a few videos on repairing / replacing brakes, but nothing for my mower specifically and I can't find anything that talks about the aspect of the break that I need. This is my first rider mower so this is all new territory for me. YTF24V48 Husqvarna. Any ideas??
