We bought our first ztr when I was in the 7th grade-my brother was a freshman. It was a Bunton gear drive-we used it on about 10 lawns. Man were we dumb. We did not know how to grease the thing. I had never seen a zerk. After the blades started to squeak, we figured something was wrong and spent a whole saturday figuring out the process.We're city boys. Took the thing to the dealer to have the blades sharpened because could not get them off, much less grind them. Bent the controll rods that lock the brakes on twice ($120) because we did not know how to tie it down. The second time was leaving the dealer after the repair for the first. You should have seen those guys laugh. On the positive side, we have grown. We now have 70 mowing customers, 2 Exmark Hydros, A load of Stihl equipment, and a lot of knowledge. It's amazing what you will learn in 5 years. Looking foward to season 2003 Oh-we have upgraded our earnings from $10 to $30 dollars an hour!
