摘要：
A depth adjustment assembly for seed planting unit of an agricultural implement may include a cam member rotatable to adjust a vertical position of a wheel of the unit relative to a ground engaging tool of the unit. The cam member may include a first engagement element. The depth adjustment assembly may also include a locking member having a second engagement element and a biasing member configured to bias the cam and locking members together to engage the first and second engagement elements and maintain a rotational position of the cam member relative to the locking member. When the first and second engagement elements are disengaged, the cam member is rotatable relative to the locking member to vary the penetration depth setting.
