The Restorer ALD-E has the same core features as the ALD-S, including 450 mm discs, steering legs and discs and a 260 mm point-to-point leg stagger, but is built as a stand-alone machine working with a hydraulically depth adjustable rear packer roller. The ALD-S is a toolbar that can also carry or tow other equipment.

The Restorer ALD-E is available in 3, 4, 5 and 6 m working widths, with legs set at 500 mm spacing. Each leg has a large 450 mm cutting disc ahead of it, and the rear packer roller is hydraulically depth adjustable to control working depth.

A low disturbance subsoiler relieves compaction below the surface without inverting the soil or leaving a rough finish. On Ryetec Restorer machines, a large cutting disc slices the surface ahead of each low disturbance point, so the pan is fractured to improve drainage and rooting while surface disturbance is kept to a minimum.

Choose the Restorer ALD-S for a versatile 3–8 m toolbar that works front or rear mounted with a drill or cultivator; the ALD-E as a stand-alone arable subsoiler with packer; the PHT to run close-coupled ahead of a PTO power harrow; the Track Eradicator to target wheelings; the GLD for grassland; or the Riot for one-pass subsoiling, mixing and consolidation.

Shearbolt or shearbar protection is the simpler option: a bolt shears when a leg hits an obstruction and is replaced before carrying on. Auto reset lets the leg ride over the obstruction and return to work automatically, which saves downtime on stony ground. Most Ryetec Restorer models offer both; which one is standard depends on the model and working width.
