Concept:-
- The Twyman tapered hammer weight system is a registered design.
Design Registration No. 3019254
- Part of the tapered hammer weight slides inside the mast. The centre of the weight is directly over the post for maximum impact.
- The Twyman weight and mast combination reduces friction, weight bounce and maximises impact to drive posts straighter and much faster.
Model Combinations:-
- Mast on arm for left, right hand or behind tractor working.
- Mast on telescopic arm for sideshift through 180 °
- Rock spike Bullet attachment for hard ground conditions.
