Hello everyone, I have decided that it is time to upgrade from an old mower to something fairly new. The Grasshopper still runs great and cuts fantastic, but it is almost 25 years old with quite a few miles on it. I am blessed to have such a good machine, but I think it might not be a bad idea to get something fairly new. Although I can't afford a new one, I am going to save up for a used one in good shape. What draws me to the stander concept is the versatility and they don't take up much trailer space, which is a plus for me since my little trailer is only a 5x8. I'm looking at the Deere because I have always liked their tractors & 21" mowers, I have read nothing but great reviews on the 7 Iron deck, and I like the height adjustment system on the quiktraks. Since my trailer is small, I am limited to the 647 or 657. Which I assume is the same machine, besides the deck size. I know these machines are built like a tank and 600-1200 hours would be nothing on them, but I am still somewhat nervous about handing over $3000-$3700 for one. This is my first big purchase, so I have a few questions If you guys don't mind. Please be honest, you wont hurt my feelings. 1.Would it be worth it to spend $3500 on a machine with 600+ hours, as long as the mower is in good shape and has had regular maintenance done each season? 2.Is there anything in particular I need to look out for when I go look at one? 3.Would a quiktrak with high hours last a pretty good while before I had to start replacing parts(Hydro Pumps, Wheel motors, etc..)? 4.Do they hold pretty good on slopes, even with my 260 pound rear on the back. 5.How does the 7 Iron perform in wet grass or thick weedy grass? Thank you very much in advance and I look forward to reading your opinions.
