SOURCE: engine code p0420
The P0420 code is set when the oxygen sensor after the catalytic converter gives a reading the same or very close to the reading of the oxygen sensor(s) before the catalytic converter.
There are usually three possible causes...
The front oxygen sensor (before the cat) is giving an incorrect reading.
The rear oxygen sensor (after the cat) is giving an incorrect reading.
The catalytic converter is not working properly.
Since you recently replaced the cat, the logic points to the sensors, but it could be the cat again. Aftermarket converters are usually smaller than OEM and don't last as long.

Our Subaru encountered this issue several years ago under warranty. The first time the dealer replaced the front oxygen sensor. This was the cheapest repair and since it was an intermittent problem I am sure they hoped to delay the issue until the warranty was up. The second time they replaced the catalytic converter and we haven't had any more issues.

I do think the same way. If the pads look flat and not so worn have the rotor turned to eliminate the squeaksyou are encountering

I think either the bolt holding the left blade onto the spindle is loose, or the cup washers under that bolt are flattened or missing. As a result, the blade is slipping on the shaft and probably making a squeal or squawk. Take off the deck, flip it over, and remove the blades. Note if the bolts seem tight. And look at the washers stacked under the bolts. Replace any missing washers, or flattened cup washer. Make sure the cup washer faces the right way (hollow side toward the blade). Tighten things back up securely - it takes a hefty pull on the end of a 2 foot long wrench to get enough torque.

check the connecting rod to the tranny. follow the gear handle and you should find a rod connecting the handle to the axle make sure you're in neutral and adjust the rod until the handle starts to move
