i've got a 1978 John Deere 205 cutter. it's 5' wide and has been indestructible in 28 years! it's compariable to the current JD LX 5(used for light mowing), and maybe that's what makes them different. all I can tell you is mine has cut everything from weeds, small trees and various bushes, to cut corn fields all day long. does a great job. i'm acctually thinking twice about trading it in when i go to trade in my tractor on a new one because its been so good for me and i'm scared to get a new one that wont hold up as well.
