How good is a 475 disc? Or are the 490 and 496 better disc? around 20 ft is what I need!

The 490 and 496 are a lot heavier. They all do a good job. They also made a 485 that is in the middle as far as weight. I don't see many of them around here. There is also the 7.5 vs 9 inch spacing debate. I have used both and both have their advantages. The 9" seems to me to do a better job as a primary tillage tool and the 7.5" does a good job on a seed bed. There a lot of 475's in this area. I have one with a 7.5 spacing. I am considering a 485 I have found that has 9" spaced blades.

How much trash? Disc are good some yrs and bad in some. Disc tend to cause compaction issues unless the soil is right. I use one on the lighter side for that reason. 475 is a good disc, just not as "heavy" as a 495-496.

I had a 475 it is a good disk. Mine had the 9 inch spacing. I had some gumbo soils. It was miles ahead of the bw it replaced.
