摘要:
A furrow opener features an opener body including a shank mount and upper and lower interface portions at a forward side of the opener body. A replaceable tip body has a furrowing portion for opening a furrow in the ground, a top interface portion at its rear for mating with the upper interface portion of the opener body and a rear accommodating portion defining an accommodating space between the opener body and the tip body when the top interface portion is mated to the opener body. An intermediate body has a mounting portion arranged to interface with the rear accommodating portion of the tip body and the lower interface portion of the opener body to fit in the accommodating space defined therebetween. The tip and intermediate bodies are separately replaceable, thereby accounting for different rates of wear at different areas of the opener.
