I have fond a good deal year after year on municiple leaf vacs. This one company was selling prior to a auction 2 1990 trailer mounted leaf vacs both had 80Hp 4cylinder diesel engines on them I beleive made by American road. They wanted 3,000 bucks for both. Has anyone experienced municiple owned equipment. I dont know the hours on these machines I have seen another municiple owned vac forsale it was a 1985 Salsco diesel...with only 950 hours on it and it looked brand new. Just curious as to how long these units are good for. I figured diesel units are good for 5,000+hours but I thought maybe leaf vacs have extra loads on them thus shorter life ?
