I believe they are made by Deere but I firmly believe they are made much cheaper. Bushings vs bearings is a great point James made. Our society wants the cheapest thing they can buy. Most people don't have sense enough to figure out how to clean an air filter. They don't want to service their machines. They don't want quality. They want cheap.
Most of the stuff sold today isn't even made to be serviced. It's made to be thrown away.
Awhile ago someone took a picture of an owners manual for a new lawn tractor and it said the life expectancy(or serviceable use) was something like 250 hours. That's not a long time. The cub 128 sees 5 or more hours a week cutting grass.
The original poster said he has a half acre. So maybe 1 hour a week. That's a few years of use.
The cub 128 I plan to give to my son one day. I bet it will still be running just fine. The original motor went from 1973 to 2014 before needing rebuilt and even then it was just a hone and rings and new gasket set.
OP you can probably see a lot of us here are pretty passionate about garden tractors. We may all be a little nutty!
If I had 2 grand to buy a tractor. Craigslist to find a 500 dollar 70s cub in good shape. Tear it down replace bearings, check for leaks, repoace belts, change all tge fluids ect. Put it back together and run it. Might be out 700 for the total package. Then you'd have a solid tractor that will run for another 50 years.
