I debated buying either a plow attachment and/or ~72" snowblower, and the jury is still out on the blower, but am pretty sure I can survive without the plow. I had my first real test of snow removal using my JD990 (with 430 FEL) in early November.
I was able to push the ~12" of snow forward, and my ~1700' driveway has two or three well-placed sharp turns that allow me to just keep pushing the snow until it is off the drive. Then I back up, and can tackle the next segment with no hassles.
I was very surprised to see how well the 430 handled the snow, and I had just received an earful from my sister (also my neighbor), and my wife, the morning of the big snow, for not buying the Woods SB 74 blower. I had been eyeing it up, as a dealer told me it can come in John Deere green.
But now the blower now seems like an unneccessary expense.
The biggest challenge, I find, is plowing low enough for 2wd cars to navigate, but not so low as to scrape the rather fragile oil and chip driveway.
