I've got 100 acres of newly seeded CRP and just finished mowing it the first time (barely) with an old 9' sickle mower. A disc mower would probably be the least cost and be used on my old 4020. A bat wing would be much faster and I'd use my 4640 with cab and A/C, but it would be the most costly it seems.
Will need to mow it at least two more times this year, at least twice the next two years. The 100 acres consists of sidehills, flat ground, and some rocks in a two acre area. Lots of turning and small fields.
Thoughts and opinions appreciated.
