“Installed on my C232 New Holland Skiid steer. 150/track is the way to go for my steep paved drive. Grip studs are awesome, a bit expensive, but I'm cheap. I tried to skimp by splitting 150 studs between both tracks of my skid loader. Nope. Listen to them when they say 150/track and they work like a charm! No more sliding down the driveway for me. No regrets, well worth the price”
