Gotta be honest with you - I think you should be looking at a R62 for that number of acres. I believe our field and yield situation to be quite similar to yours out there in PA. Most of our fields are 20 acres or less, quite a few, if not most, are odd shaped, hilly, ect. Even have a few guys we cut for with big oak trees and_or windmills out smack dab in the middle of their fields making things even more interesting. Yields average approx 150 for corn and 35 for beans. On an average day with our R52, we can do 4.5 - 6 acres per hour (clock hours, not separator hours). We unload on the go when we can, which is seldom. We can really increase productivity if we can. Even when we can, the combine still has to wait on occasion depending on the haul with the cart. Also, we do the greatest majority of our corn as high moisture, which really limits your capacity at the shoe - running without a sieve helps, but some guys don't want the cob bits. If you run a sieve with 30% corn on a 52, you'll be running 2.5 mph on the flat. We are seriously tossing around going to an R62 simply for the added shoe capacity in high moisture corn - we sure don't need (and really are not equipped) the extra capacity otherwise, especially running 6-30. With that number of acres to cover, I'd say go with an R62, have a big cart and trucks, or lots of wagons. All the help you can find to keep the grain away from her too! If you are filling silos, get a BIG roller mill and a really big wagon sitting at it and use a cart to fill the wagon. We use a 1200 Automatic roller mill run by a 7085 Deutz Allis, have a 250 bu Walker power unload gravity box that we fill with our grain cart. We can keep the roller mill running at capacity on close fields so a 62 and a bigger cart would bury it. When we get into dryer corn, like 20% or under, the 52 acts like a whole different machine. You can really knock down a lot of acres if you're equipped to keep grain away from it. Be sure to let us know what you decide - I'm curious as to what direction you take. Tom langan
