I got to know it better in the summer of 1970 when I was hired to work my uncles's summerfallow fields. Health problems had kept him from doing any work on these fields that spring. Good summerfallow needs to be started on by mid June at least. By July it becomes a challenge with the big weeds that are taking over. By the time I got to it in August it was almost like breaking new prairie sod, except with much more weed growth that constantly plugged the John Deere cultivator I was using to work it. That 16 footer was a good load under normal conditions but in these extreme conditions it was a hard workout for the old 730 and there were more than a few times I saw the front wheels lifting off the ground as it struggled for traction as the cultivator spikes were tearing up the thick twitch grass sod. I don't recall how many fields or acres I did but no doubt by the time I finished the last one it was time to start all over again.
As a novice tractor operator I learned a lot that summer. We both survived although the tractor has a few dents in the lower fenders from the many times I jack-knifed the hitch backing up trying to unplug the weeds from the cultivator shanks.
My uncles are gone now and the 730 is "semi-retired". A reminder of times past every time I drive it.
