This is the plow to use in what would normally be described as “uncultivatable” country. With these plows a rocky hill can be turned into a valuable pasture paddock. For plow sizes see Page 19 and 21 and
The assemblies use a totally new and patented high pressure Impulse Ram. With these rams, if the plow point hits a rock the resistance or break out force can reach three tonnes. Then, if the rock hasn’t moved after the plow has travelled forward a few inches, the ram pressure automatically switches over to normal line pressure. This allows the breakout forces to reduce to around one tonne and the shank to jump the rock and return to its operating position.
In action it works like a deep digging rigid shank, that can change to a stump jump shank for a few seconds, when it’s absolutely necessary. It’s incredible to watch the thing in action. To our knowledge, there is no other implement anywhere in the world, that has this capability. It’s uniquely Australian. T
