A field marker is mounted on the rear corner of the seeder or cultivator frame so that its weight is supported by the packer wheels or support wheel axles at the rear of the frame, thus minimizing the imbalance and uneven seeding that will occur with marker mounted on the front corner. The marker arm is slidably extensible to avoid complex knee-action joints and the mechanisms required to operate them.
