It is powered by an 18hp Briggs & Stratton Vanguard OHV engine and uses hydrostatic drive — so we know it’s going to be easy to use.
The main attraction is the working depth. The 7007H works to a depth of 150mm, using either coring or solid tines, and gives the “forced heave” we expect.
The Verti-Drain’s action is down to the “adjustable parallelogram system”, which ensures the tines enter and exit the ground cleanly and vertically. This is perfect for hollow-coring tines, but for maximum compaction-busting with solid tines, the forced heave is set at an angle of 24?. The tine kicks back in the ground to shatter the pan and introduce air. The force does not rely on the forward movement of the machine, so there is no drag as the tine enters and exits the soil.
The 7007H is equipped with biodegradable hydraulic oil as standard. Maintenance is a simple matter of greasing and checking the oil before use. Tines are changed in the same way as on the larger, tractor-mounted Verti-Drains.
The 7007H has a forward speed of over 10.5km/h — fast for an aerator, especially a deep aerator — giving a working capacity of over 2,120sq m per hour.
