We all know that if a mid-mount ZTR has too much weight on the rear of the machine, you will do a wheelie. Likewise, if you have too much weight on the front of the machine, you will suffer traction. If you see a mid-mount ZTR with a catcher added to the back, you often see some counter weights added to the front. I am sure that most manufacturers have a target (rear to front) ratio that they engineer to. Does anyone know what this ideal ratio is? Has anyone ever weighed out their mower (based on rear to front)? One other factor that must be factored in is that of the seat placement and the average weight of the operator. While we are at it, which mid-mount ZTRs do you feel hit or misses the ideal ratio based on your experiences.
