Reversible agricultural implement tine - is bolted to support so one working end projects only

摘要

The blade (2) fixed to the support (1) is V-shaped, with bevel-ends (3, 4) and has in the centre, a bolt fixing it to the support (1). The support is rounded at the top to match the rounded shape of the blade (2) and consists of a bore-hole (5) into which is inserted a bolt on which is screwed a nut (6). When one end of the blade is worn down, the bolt may be unscrewed and loosened, and the blade pivoted for the other end to protrude. The end (9) of the support is polygonal and ends in a threaded section (10) on which is screwed a bolt (11) for fixing the tine to the harrow.
