| 説明 | I had originally set the tractor wheels as close together as the would go in order to get the most rows onto the field. We have recently been using more plastic film for weed control and to warm up the soil in the spring. The wheel spacing was too narrow to go over the plastic for cultivation without damaging the plastic. So I had to move the wheels out.The wheels are designed to be mounted in any of four positions, so there are eight possible wheel spacings. The note shows one of the flanges mounting the tire to the hub. The narrowest spacing is when the tire is mounted on the inside of the hub (using the bolt hole on the right in the note). Here I have moved the wheel out one notch. I did the same on the other side. That changes the spacing by about 2.5 inches on each side, 5 inches total.To get the other two positions, the hub is also removed and turned around. It has a slight dish shape inward here. Moving it so the dish is outward gives you the other two positions.Moving the wheels was fairly simple, but aligning the front wheels afterwards took two days. |
