Abstract

Turf aerator (11) has a reciprocating drive mechanism driving rigid tine leg (35) pivotally mounted at connection (36) to a drive assembly arranged to reciprocate tine leg (35) along its longitudinal axis. The drive assembly comprises reciprocating drive member (33) including a first pivotal point or connection (36); a second pivotal point (34) connected to first eccentric (57); and a third pivotal point (58) connected to second eccentric (38); third point (58) being located intermediate first and second points (36, 34). First and second eccentrics (57, 38) are rotated in synchronism to vertically reciprocate first point (36) whilst simultaneously reducing the extent of horizontal reciprocation of first point (36). Reciprocation is controlled in synchronisation with forward motion of aerator (11) such that a uniform pattern of holes is punched in turf surface (52) as aerator (11) advances.

(57) Turf aerator (11) has a reciprocating drive mechanism driving rigid
tine leg (35) pivotally mounted at connection {36) to a drive assembly arranged to reciprocate tine leg (35) along its longitudinal axis. The drive assembly comprises reciprocating drive member (33) including a first pivotal point or connection (36); a second pivotal point (34) connected to first eccentric (57); and a third pivotal point (58) connected to second eccentric (38); third point (58} being located intermediate first and second points {36, 34. First and second eccentrics (57, 38) are rotated in synchronism to vertically reciprocate first point (36} whilst simultaneously reducing the extent of horizontal reciprocation of first point (36). Reciprocation is controlled in synchronization with forward motion of aerator (11 such that a uniform pattern of holes is punched in turf surface (52) as aerator (11) advances.
