I still see negative comments about the m graders. I think they are a great machine.I have over 5300 hours on my 14m and i have had very few problems with the machine.I had a 14g and 2 14hs before this 14m but this m is a much better machine.when working heavy windrows the front end on the m doesn't slide like the h,it has more power (70 hp in 3rd gear) and the cab is very quiet.The joysticks make mutiple functions very easy as compared to the h.As for older operarors I was over 50 when I got the 14m and the first week I had it I was cutting shoulder lines.The first mile I did was slower than with the h but it wasn't long before I prefered the m over the h.Cat has been very good with updates.One update slowed the steering about 30% and the latest update I have slowed the steering again at higher speeds, and I also have the new software which allows you to select different settings for blade control fine -normal-coarse.This is a great feature that makes the m even better.If you have a chance to run an m don't hesitate accept technolgy or be left behind.
