Clearing Trails With the Cheapest Skid Steer Sickle Bar Mower I Could Find

I bought this cheap sickle bar mower to cut off limbs and branches that hang over our trails. I set up the mower and trimmed about 2 miles of trails. It works, but you definitely get what you pay for. I've already broken 5 teeth and I'm hoping they were just cheap teeth that came with the mower. If you've got experience with sickle bar mowers, please let me know which brand of teeth I should buy as replacements! The mower is Wolverine and I bought it new from Ebay.
