A tiller with chassis, pair of handles, and tines, wherein simultaneously raising one handle and lowering the other twists the chassis to lower one tine and raise the other. The tines comprise pairs of blades, each blade having a pair of upturned tips. The height of tines is adjusted by adjusting the support for wheel means. The tiller is supported by an arm having a single ground engaging wheel means, pivoting the arm and locking in position to adjust the height of the tiller. The tiller includes a third handle located along its chassis. The chassis is formed from two longitudinally split components. A blade cover for the tiller is thin and curved to lie in an arc spaced from the rotating tips of the tines. An attachment for the tiller has a V-shaped tip and shaped to form a furrow.
A garden tiller comprising an elongate chassis steerable by a pair of spaced apart handles and supporting a power unit, a single ground engaging wheel means which is rotatable about a horizontal axis and which supports said chassis in the manner of a wheel barrow with said power unit and the centre of gravity of the tiller being between said ground engaging wheel means and said handles, at least two tines rotatable about an axis substantially parallel to, and in front of, said wheel axis with said tines being spaced apart on said tine axis, said chassis defining a central longitudinal axis of said tiller, said power unit and wheel lying substantially in a substantially vertical plane containing said longitudinal axis, wherein simultaneously raising one of the said handles and lowering the other of said handles twists said chassis about said longitudinal axis to tilt said tine axis and thereby raise one of said tines and lower the other of said tines.
A tine arrangement for an agricultural tiller, said arrangement having a plurality of tine groups, each said tine group comprising a pair of tines with each tine comprising an elongate central portion and each having a pair of upturned tips located one at each end of said central portion.
The tine arrangement as claimed in 9 wherein said tines are arranged along a substantially horizontally extending axis with at least one spacer co-axially arranged on said axis adjacent each tine to maintain a predetermined spacing between said tines.
A method of tilling ground comprising the tilling of soil by rotating tines in said soil, said method comprising the steps of:
A method of tilling soil using a tiller having a motor and a plurality of tines each rotatable in a substantially vertical plane, mounted for rotation about a substantially horizontal axis, and powered by said motor, said method comprising the steps of:
In an implement having a chassis, a ground engaging wheel means supporting said chassis, a pair of operating handles at one end of said chassis, at least one cutting blade at the other end of said chassis, and a power unit supported by said chassis and arranged to rotate said cutting blade(s), the improvement comprising a third handle extending at least part way along said chassis and located close to the centre of gravity of said implement.
In an implement having a chassis, a ground engaging wheel means supporting said chassis, a pair of operating handles at one end of said chassis, at least one cutting blade at the other end of said chassis, and a power unit supported by said chassis, and arranged to rotate said cutting blade(s) via a gearbox located intermediate said engine and said blade(s), the improvement comprising forming said chassis from two longitudinally split components which form a housing for said gearbox.
A blade cover for a garden tiller having a longitudinally extending chassis and a transversely extending shaft with a plurality of tines, said blade cover being substantially thin, being curved to lie in an arc spaced from the rotating tips of said tines, and being attached to said chassis by a single fastener which passes through an opening in said cover and into said chassis.
An attachment for a tiller having ground breaking tines, said attachment comprising a substantially V-shaped tip located to the rear of said tines and shaped to form a furrow in ground tilled by said tines.
