yesterday I was approached while mowing by a guy who wanted to sell some equipment. He only lived 2 blocks away, so I locked up my stuff and went with him to see the mowers. His english wasn't great, but it sounded like he has a new job and doesn't want to mow any more. One mower was a classic t-bar 37" toro belt drive walk behind. This is the one with the recycler deck and two different blade sizes. It looked pretty good and mowed good, not too much wear on it, also it had a 15hp kohler. For this one he said $900 but then said maybe $800. The other mower was a toro/suzuki 21" . engine manufacture date said dec. 2002. It looked very nice, much better than mine which has been used for 1 year. So I'm guessing it probably only has 6 months use on it. For this one he wants $500 firm. I was checking this one out and noticed the blade was on upside down!?? I'm wondering if he can't put the blade on right, could he have also put plain unmixed gas in it? It did run good though. So what thinks you guys? I'd sure like another 21 with the suzuki to last me a little further into the 4 cycle future. Do these sound like pretty good prices? If the guy ever did put unmixed gas in it could it be damged bad, even though it runs good and sounds good? thanks for any advice.
