I had a new Howard Rotovator delivered with my tractor. The only time it has been used was for less than a minute to see how it worked. I noticed a few days later a puddle of oil on the garage floor. I called the dealer, they came and got it and supposedly fixed it. I noticed a few days afterwards it's leaking even worse now. The dealer said they had to reweld a spot and they seemed perplexed it still leaks. I'm wondering if I should insist on a whole new unit.
