I trashed the mower deck on my JD tractor type mower by hitting a tree stump. Found an exact replacement online. installed it under the tractor. as soon as you engaged the blades the tractor died. Spent hours going over it and never found the problem so I took it to a local independent mower repairman. He ended up getting a 'parts picture' of the mower deck to determine it was assembled incorrectly at the factory. A washer was placed above a bearing on one of the spindles rather than below it causing it to bind. He charged me $140 labor which I was happy to pay him for his work. I contacted the seller.....rather than ship it back to him he credited me $70. My point is take it to an independent repairman, could be money well spentThat sucks about the bad service! I’m not familiar with Enid Atwoods. But the one in Norman is usually decent.
I will say though, if you are mechanically inclined it’s probably a simple fix. Most of those lawnmowers aren’t too terribly complicated. I bet a small engine shop could fix it pretty easily if you’re not into wrenching.
that being said it definitely sucks to have to work on some thing you just bought
