I lived in the city for most of my adult life. Recently bought a home on 2+ acres. Bought the 25 year old JD model 265 that was available at purchase. It has worked great for last 3 years now is slowly dying. In my research to replace it I have discovered at least in my perception that all the E models from Loews etc, the x 300 models and the x 570 are virtually the same except of course the price. The size of the trans axle may be the only difference except they are still aluminum rather than cast iron. I bought the 570 and was disappointed to find the E180 came standard with larger front tires. I was disappointed that the front axle assembly is same across the board for the x300 series as well as the x570. I am beginning to doubt that there is any difference in the frames for the E series through the x 570. It seems to me that you don't even get into any real quality until maybe the 580 and above.I just dont see the quality between the e170 and the x570 being worth $3300 more or even close. I have 45 very large trees on my property, the lawn is very rough and areas are very swampy and ditches along the front and I have to pull a large (60 bu capacity) leaf vacuum/chipper and dont think these lower end JD models will handle the stress. Is there anyone out there who may inform me otherwise?
