Gauge wheel device, row unit, agricultural implement and method of operating gauge wheel device

A gauge wheel device for maintaining working depth of a row unit included in an agricultural implement, comprising:

• a gauge wheel arm which, at a distal portion thereof, carries a gauge wheel which is rotatable about a gauge wheel shaft,
• a mounting member that extends along the gauge wheel arm,
• wherein the gauge wheel shaft is fixed at and extends perpendicular to the mounting member, and
• wherein the mounting member is mountable in at least two different positions relative to the gauge wheel arm,
• wherein the mounting member forms a substantially flat and elongated part, and
• wherein the mounting member has a first fixing device at a first end thereof and a second fixing device at a second end thereof, wherein the gauge wheel shaft is connected to the mounting member at a shorter distance from one of said fixing devices than from the other, such that an effective length of the gauge wheel arm is variable;
• and
• wherein the mounting member is pivotally mounted to the gauge wheel arm around a pivot axis located between the gauge wheel shaft and one of the fixing devices.
