I would say the R42 would be comparable to a 6620 but the R52 would definatly be more like a 7720 if not larger and with a bigger bin. The Gleaners do very well on sidehills just as they are. By seperating the grain and distibuting it above the accelerator rolls just above the front of the sieves, the grain has no chance of going to the downhill side until it is on the sieve. The accelerator rolls propel the grain down onto the sieves so that a blast of air can remove a lot of the chaff before the grain lands on the sieve thus it is less likely grain will ride over. As one operator told me once, the sieve is just there to catch the grain as 80% of the cleaning has already taken place.
