I've read some very informative related posts here. I do think I'm going to need to purchase a replacement, preferably with a 38" deck but they don't seem common these days, so probably 42". I've got 2 older tractors in my garage. I found out the 420cc Craftsman I've been using for the last several years has a Zongshen engine made overseas. Maybe ~180 hours on it. I do believe it has a bad head gasket. The 38" Bolens has a few issues, and is 18 years old. I'm thinking now is the time to spend more for a John Deere, Cub Cadet, Husqvarna or other high end (to me) tractor. I'm in my 60s and although I can work on mechanical projects to a point (replaced an engine in an Agway lawn tractor ~35 years ago) I'd like to get something that will more likely be more reliable than the common brands. At this point I'm not so sure I want to be routinely be working on them like I've been trying to do lately.
Reading reviews (for what they're worth) by owners, it seems the high end tractors don't fare much better than lower priced brands. Broken belts prematurely, dead batteries, or even bad engines (on the lower priced models). I know MTD makes lawn tractors for various brands, but I wonder, based on owner's experiences on this forum, has buying a more expensive model with a good reputation in the past resulted in better reliability and performance? It seems so many products have the 'They don't make them like they used to' label.
When searching on automotive questions I've been led to this site and have read some very good information.
