I agree that a smaller tractor would be nice.  The last couple years I have used an Oliver 1655.  However, this tractor is not available for this year.  I would love to remove the fluid in the tires but I do use it for some tillage also.  A friend of mine has offered his JD 3020 to me to use to plant corn.  The problem is the tractor is about 1 1/2 hours away and he would need it back for hay.  I usually would be done in plenty of time unless we have a very wet spring.  The more I think about it the more I like using the 3020.
