Semi-automatic baler control and indicator system.

摘要

A round baler (8) having a single bale forming chamber is provided with an electronic control circuit (10) which makes its operation automatic except for the operator-controlled functions of starting and stopping forward motion of the baler (8). Under the circuit control the baler (8) forms a bale (R), wraps it with twine, cuts the twine, raises the tailgate (6), ejects the wrapped bale (R) and closes the tailgate (6). The control circuit (10) energizes a first indicator (G) when the tailgate (6) closes to signal the operator to begin forward motion of the baler (8). When a point is reached in the baling cycle at which the wrapping of the bale (R) is to commence, the circuit (10) energizes a second indicator (R) to signal the operator to stop forward motion of the baler (8). The circuit (10) also detects certain malfunctions and energizes a third indicator (Y, 20) to signal the operator that a malfunction has occurred.
