I pulled the New Holland 975 Combine Wednesday to another farm with a M602 Minnie-Moline. It was about a 10 mile trip up and down hills on mostly rock roads. It had started raining and turning to snow about the time we got started and it occured to me starting up the steepest hill "What am I going to do if it starts spinning and I get stuck??? We made it up and down all the hills without an accident or trouble but it seemed to be an awful heavy pull for the old M602MM. Anyone know what a rig like this weighs??? Took the grain header a week ago on a flatbed and that went much better.
