We had a Lely lotus 300 tedder rake. It was only 3.0m wide and had 2 rotors and would rake to the middle. The cranked tynes could sweep the ground well and pull apart lumps. It had 2 baskets that folded down when raking or shifting a row. When the tynes were shifted to the tedding position it would spread the grass as far as you want. It was also a cheap and simple machine. We only sold it because we went to a 5.5m tedder and 6.8m twin rotor rake. I would buy one again. I found a link:
