This will be my first year harvesting my own hay. I have some questions about the H7450 float. I have read the manual several times and looked online. So, the springs have different amounts of thread showing. One side feels heavier than the other, and when you raise it, one side comes up before the other. Based on what the manual recommends for field conditions and ground speed, I think I want around 110lbs on each side. What is the best method to weigh this? Spring scale? I feel like there must be a more accurate method than just lifting and comparing, right?
