Deere, like many other manufacturers, makes different levels of product, sometimes to meet price points. No matter what the product is, when you build to compete at a price point, you make compromises and sacrifices.....
The "bottom tier" of Deere equipment has been built to compete with cheap mowers and mass distribution at the "big box stores." Not saying it is necessarily a bad product, but they won't take as much use/abuse as the more expensive models.
Another example is briggs (or kohler, or...) engines. They make a a base model with plain bearings, splash lubrication, aluminum cylinders, etc. Much cheaper than the "commercial grade" product by the same manufacturer, which have ball bearings, iron liners, pressure lube, etc. The cheaper engine would work fine for what many of us would use it for, but don't expect to use it for many years in a daily use mower...
But back to Deere..:laughing:
Personal opinion here, but I don't think even the upper tier Deere mowers are built as well as they used to be. Manufacturers don't overbuild to last anymore! I have 2 older garden tractors, both from the 70's; a ford LGT165 and a Deere 316K. Both lived hard lives before I got them. Both came with heavy(!!!) steel frames and cast iron engines (that can be easily rebuilt). Both still going strong and with moderate care, will outlast me! I don't think a modern Deere product will be around and in that kind of shape in 40+ years!
But depends on what you want, how much you want to pay, what you want it to do, and how long you want it to last....
