Product Overview
The Tremor®subsoiler from Unverferth is designed to be tough and aggressive. Its parabolic auto-reset shanks, with 6,000 pounds of trip pressure and a working depth of 20 inches, are built to rip through the heaviest compaction and shatter hardpan. Shear-bolt protected shanks, with 7,500 pounds of shear pressure, are also available.
Feature Overview
- Parabolic-shaped shanks for maximum soil disturbance
- Welded, heavy-duty, double frame with 6"x 6" rear bar for increased strength and durability
- Units factory assembled for 30" spacing, and an innovative frame design with bolt-on frame extension allows the customer to vary shank spacing from 20" to 40"
- Gauge wheels with new 7.6Lx15-8 ply tires standard on rigid units, and 9.5Lx15-8 ply tires standard on folding models
- Swivel coulter with 20" rippled blade cuts residue ahead of shank for optimum trash flow and features 1,500 lbs. of blade down pressure for optimum penetration
- Auto-reset shank design allows shank to trip rearward and upward without use of shear bolts providing 6,000 lbs. of pressure per shank for consistent working depth
