I’m trying to master blade setup and finding it tricky to get the right angle and tilt for different materials. For example, what works best for gravel vs. dirt vs. asphalt? How do you adjust for cutting versus spreading? I’ve heard the “rule of thumb” about blade angle but want real-world advice from experienced operators. Also, any tips on setting up for crown and drainage? I want to produce a professional finish every time — not just “good enough.” Thanks for sharing your techniques!
