I have looked all over to find a formula I have seen in the past, one phrase I have heard is to calculate the sum of the moments, using that phrase I haven't found what I was looking for or at least it wasn't the same as I recall it. Heres what I want to do, I am working on a project similar to a front mounted zero turn lawn mower Grasshopper(r)is one of this type, ok I need to know the calculated weight on the front (drive)axle, I don't have the exact measurements available yet, If I have 200 pounds mounted forward of the drive axle, and 100 pounds half way between the front axle and the rear axle, how much weight is actually on the front wheels centerline?, for example the 200 pounds attached 18" ahead of of the front wheels, and the 100 pounds is 18" behind the front axle, what is the weight on the front wheels (2)?
