Moved and spread out a big pile of wood chips with the 4150, and also box scraped my firebreaks nice and pretty, which my wife really appreciates when she takes the dogs out for a walk. When I was heading back in through a gate I had to open and close I noticed a thick piece of wire sticking out one of the front tires. This was the first time I have ever had to plug a tractor tire and the repair seems to be working well. 39 hours now on the machine and no problems so far.
