If you own a plastic transmission, pull it out. Take the same pulley out. Take the bottom cage off and replace the bearing with a timekin 35x17x10mm bearing. Its the bearings that freeze and blows up your stuff. Put in a real bearing and it will last forever
If caught early, cleaning out grass and debris from that top pulley area will extend the life of them. It's still a inherently poor design for a transaxle though.
I have a Husqvarna ST 138 2015 model. when I push the forward pedal the mower goes in reverse, the reverse is okay, but the forward goes in reverse too..? Its got me beat.. Should I give this a try..?
Based on the amount of possible "dead" transmissions discussed in these comments, I'm hoping that someone might want to sell me a Primary Variable Speed Drive Pulley for my Craftsman 19.5 HP 42” LT2500 Lawn Tractor. (Sears Craftsman Model Number 944.602630). As discussed here in 2009 (for this one year only) Craftsman decided to use the problematic (plastic) General Transmission (GT/Gentrans) RS800 Transaxle. The tag attached on the transmission reads General Transmission 415663 (87007 C4) and 415663C0100033. It is a Continuously Variable Transmission (CVT)) and not a hydrostatic drive.
