Description: |
| Abstract:
My invention relates to harrows and cultivators and consists in a harrow-frame having converging detachable side pieces and central brace, in combination with reversible tooth-bars; also, in a rockshaft applied to the rear end of the harrow-frame, provided with wheels for adjusting while at work, and transporting the harrow to and from the field, which wheels may be operated independently of the harrow-teeth; also, in a novel combination of a flanged washer with each tooth and the beam. These washers embrace the shank of the tooth under the beam, and the flanges clasp the lower edges of the beam, binding them together and adding the strength of the washers to the weak parts of the beam and teeth; also, in a novel shape of the harrow- teeth, whereby they are strengthened on the line of the draft, and are enabled to cut the soil with great facility and the least resistance.
Claim:
The harrow-frame having the converging detachable side pieces B and central brace F, in combination with the reversible tooth-bars C. |
