Now I can't speak to your experience, what the model was (because they have made some really crappy ones for people who only have a few $), the condition, new or not, (you don't seem like a buying brand new kind of guy, so I am surmising you bought a used one...for cheap), but again, I don't believe a blanket statement that ALL new Cub Cadets are junk is fair or remotely accurate.
To put this in a perspective, John Deere makes the D100, but doesn't mean all John Deere lawn tractors are junk. You are a guitar guy, so...Gibson Guitar makes the M2 and the Firebird Zero, doesn't mean all Gibson Guitars are junk. The Cub XT3 is a pretty robust machine. Guess what??? It will plow no problem. Slap a JP sleeve hitch on it, wheel weights and ag tires and it will plow as much as a garden tractor should. Hands down.
Fancy??? It's a $5000 garden tractor, how fancy can it get??? It has power steering, electric like many snowmobiles, ATV's, RTV's and some cars. Fancy? It has tilt steering, that's pretty fancy I guess. Plastic Hood, like almost every GT tractor made in the last 20 years including JD X700, X500. Oh...it has a drink holder that doubles as a hole to stuff a pair of gloves in if the square holder behind it is full of fancy stuff.
I just really hate these anecdotal opinions. For the people who have the money, want a new and 100% reliable machine to get the job done, let us spend our money. If we want old iron, we can surely afford it.
