20/25 HP. We can cure many complaints by modifying shock dampers. Grooved springs are an advantage. In exceptional cases low rated springs which are now standard are necessary. PH.II. Increased lubrication and higher shock damper loads effect a cure in most cases but low rated springs are sometimes necessary. Controllable dampers on 40/50 HP. should reduce complaints.
