:smile: I did not mean to imply, that you were building racing mowers. The reason I suggested the heymow, you can see what they do with thier front axles, kill switch (jet ski setup good idea)and brakes. Using the stock brake attached to the transaxle, if you break/lose the belt you have no way of stopping the tractor. Cast iron being brittle it does take much of a hit to snap one. J-spindles, there method of retaining the wheel, leaves alot to be desired, For safety, I would drill and tap the spindle for a 5/16 -18/24 grade 5 bolt and a big flat washer along some blue lock-tite, also add a guesst to the j for added strenght. Check other builds on the heymow site, there is some interesting information. I fiqured that you were a dirt track racer from the picture. There is chance of getting hurt, wether your are racing/off roading a mower or everyday life. Why bump up the odds?
