A locking structure for a disk tiller or the like which simply and quickly secures the rear furrow wheel in either an operational or transport position. An elongated link is pivotally connected to the disk tiller frame. The link is received in a guide structure carried by the disk tiller frame and is reciprocably shifted to vary the angular position of the rear furrow wheel support arm relative to the disk tiller frame. A pair of horizontally spaced latching pins are carried adjacent the guide, are biased towards the link and are selectively and alternatively engageable with abutment surfaces on the link to secure it in either of two spaced reciprocable positions. |
