When I was first looking for a small to medium tractor, I thought I had better get a 4x4 rig.
While owning two ford tractors 8n/9n 50s model, I was seeing these ym1700s around here for sale. So, I looked at them, even though they were not 4x4s... And the price of the one I bought was indeed fair ($3200), w/ front end loader and bush hog. It had and still has the Rice-Patty tires on the back. This little tractor has totally amazed me by clearing some underbrush in thick woods and grading the land. It has only been stuck once, and that was my fault due to sandy soil and rain that I should not have been in anyway.
Even though a 4x4 would be nice, this is more than enough tractor for me. It even handles a BH attachment on the 3-point. Drive slow and it will not buck you around. I would buy another just like it if one came around for a good price.
