no one cared that i did not receive the parts that I paid for.

Purchased these for my 5ft CountylIne branded cutter. I purchased it from Tractor Supply, which, for some reason, no longer sells any parts for it.
I purchased these blades directly from Tartar. They are a perfect swap.
No fitment or other issues at all. With the proper socket and impact driver, they were swapped out in about 20 minutes. They cut exactly as they should.
Tartar shipped the product quickly, and finding the right blade for my cutter was easy.

Not a good experience. Parts were shipped UPS which was a nightmare to deal with as they were unable to accept payments at multiple locations. Package arrive damaged and missing parts. Wasted a good day on the phone and running around to UPS locations etc. We asked if there was an alternative shipper from Tarter (told no). Long story short parts were shipped back and we are trying to resolve issue to get our money refunded.

I purchased replacement blades for my 5' rotary cutter. They are thick, heavy-duty blades and they work as expected.
