The disk one is made by J.M Co. (Janesville Machine Co.) Started in 1859 and made Disk harrows, disk cultivators, plows seeders etc.

The top wrench is a Model A Ford wrench, part number A-17016. From mid 1928 to October of 1931 the Ford script was not a requirement on Ford tools so this would be correct for those years (wrenches with the Ford script would also be correct).  The early 1928 wrench has only the Ford script, the ones from October 1931 on were marked Ford USA.

I beleive the third wrench down is a John Deere wrench.
