Combines l or M head to r52

The offset of the rotary Gleaner throat will cause major stock damage to the tires. And the Hugger for the rotaries are much better for getting all the crop into the machine. I owned an M2 with an A6-30 and currently own N6 with an R series 6-30 and the R series is a much better head. I personally would not spend the time and money on the non-rotary head and adapter for your R52.

I totally agree with John and offer another thought. Because l_M heads are so scarce you should be able to sell your old head for almost as much as you would have to pay for a much newer N_R series head.
