Crumbler® 160 Seedbed Conditioner
Proven Performance
The Crumber® breaks up clods, knocks soil off crown roots and smoothes soil after primary tillage; saves time, fuel and tractor engine hours; and promotes higher yields by creating more ideal seedbed conditions. Performance research shows that the Crumbler 160 works in the fall to provide high-quality seedbed conditions by:
  • Reducing clod size by up to 46%
  • Creating smoother valleys by up to 45%
  • Improving fall seedbed levelness by up to 55%
  • Reducing air pockets in tilled soil
The Crumbler®​​ 160 consistently exerts approximately 160 lbs/ft (240 kg/m) of ground pressure.
