摘要: The invention relates to wheeled raking machines which is rolled over the ground by a walking attendant. The raking device includes a raking head having a plurality of raking tines. The raking head is rocked back and forth to gather leaves ahead of the raking device. The rocking motion of the raking head is derived from a cam and linkage arrangement connected to the wheel. Thus, as the wheeled device is rolled over the ground the raking head is oscillated to rake the leaves.
