I have a Honda Foreman 500, too. No doubt one of the best quads ever made, in my opinion. However, I still wouldn't subject it to the abuse of using it as a primary tillage tool. Gear transmission or belt driven transmission, it doesn't matter. It'll wear out long before its time guaranteed. In fact, the belt driven transmission might actually be cheaper to fix when it goes out. The other reason is that an ATV is just not heavy enough to do a good job of tillage. The most you can do is pull a light disk. If you're trying to clear a weed/grass patch to make a food plot, you'll barely be able to break the sod, let alone really work the soil. If you can beg, borrow, rent, or steal a tractor, you'll be MUCH happier with the results and save your quad from an unnecessary beating. Now, when it comes to spraying, ATV's are perfect for carrying a sprayer.
