The Conser-Till® 690 mulch-till ripper provides a unique package of conservation-tillage features to break up compaction while keeping crop residue on the surface:

  • Shallow-concavity front disk blades
  • Proven Case IH deep, parabolic shanks with patented Tiger® points
  • Full-concavity rear disk blade

These features provide superior performance without the speed sensitivity of other-brand machines.<,/p>

Two working widths are available:

  • 12.5-ft. (3.8-m), 5-shank requires 125–250 PTO hp (93–186 kW)

Crumbler 160 Seedbed Conditioner

Proven Performance

Attaching the Crumbler® ​160 behind your Case IH Conser-Till 690 makes one-pass primary tillage and seedbed preparation possible. The Crumber 160 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. ​

Heavy-duty Construction

The Crumbler®​ 160 is constructed with rough terrain and varied soil conditions in mind. It features:

  • A mainframe and wings constructed of 6-x-4-in. (152-x-102-mm) steel tubing
  • 16-in. (41-cm)-diameter reels with 10 1-in. (25-mm)-diameter solid bars
  • 3,000 psi (211 kg/cu cm) hydraulic cylinders and hoses with ISO couplers
  • 9.5L x 15 eight-ply, tubeless-rim implement tires
  • Replaceable hubs and spindles
  • Large, heavy bearings
  • Rigidly mounted reels
  • Available in 15-,  17.5-, 20-, 22.5- and 25-ft. (4.6-, 5.3-, 6.1-, 6.9- and 7.6-m) widths. The four larger models fold to a narrow 13.5-ft. (4.1-m) transfer width.​

  • A pull frame with telescoping tongue that easily attaches to the rear hitch on primary tillage machines
