Go to each fo your local dealers, get a feel for the sales and service departments. A good dealer is a very valuable tool. You need one who can get you up and running fast in the event of a breakdown. They should have a good parts inventory and a good service department. That way if its something you cant fix yourself, they can get it done for you. Talk to the salesman. If they are a good salesman and know their product, they will know what works in your area.
Once you find a good dealer and a model that you think will work for you, its time to demo. Try the machine on your properties for at least a full day. Then try some other machines. Once you have tried a few, you will get a feel about which model is best. Then you can make your decision.
No one can tell you exactly what works for you. You need find that out on your own as what works for someone else might not be the best fit your you. It all depends on your operating conditions.
