Been looking for a used rotary cutter for my 640 Ford and ran across a 5' pull type with a good price. I have been operating tractors since I was 10 years old but the only pull type cutter I have used is a 15' batwing. Any time I mowed on my grand parents farm, it was with a 3 point mounted cutter. What are the advantages and disadvantages of a pull type rotary cutter?
