The Restorer GLD is a 3 m low disturbance grassland subsoiler that loosens the soil, breaks the pan, removes compaction and improves drainage and aeration. Discs cut the surface, legs follow to fissure the subsoil, and the cracks let roots grow, water drain and oxygen reach the soil for better grass growth and longer grazing seasons.

The Restorer GLD has a working depth of up to 500 mm, set using hydraulic packer depth control with stop spacers. The machine weighs 1,600 kg and has a heavy duty frame with Category 2 and 3 linkage, so check your tractor's lift capacity and front ballast before fitting.

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.
