I had a customer at a nursery interested in a track machine. He wanted to know why nurseries here are still purchasing rubber tire units. I had several ideas that I gave him. I told him I would see what you all thought and called a Deere dealer in the heart of nursery country to see how he was doing with track units. Give all the reasons you think and know and I will check back later in the week and tell you the conclusion I came up with.
