Just received an instruction manual for setting up and operating McCormick-Deering Tractor Disc Harrows Nos. 9A and 9B.

The disc I have is a 5 foot model which is listed as a 9A in the manual. Discs are 18 inch on mine and according to the manual the center mounting hole is a square 1 3/16. Does anybody have information regarding where I could obtain discs of this size?

Mounting hole of 1 3/16" means it would be a 1 1/8" axle as there has to be a bit of play for them to go on. Check out Agri-Supply for blades and that disk should have a 11 guage blade, not the 9 guage or even the heavier 7 guage, those are for the newer heavier wheel disks.

My uncle used Agri Supply as well to get parts to repair his Mccormick 10 A disk. He had taken his apart and measured the shaft.

Leroy,

That makes a lot of sense. I had forgotten that the disc would have to have some play to fit the shaft. 1 1/8 should be correct.

They do not have any in the stores, do not know if could special order or not. Actually no tilliage or harvesting parts to speak of.

Mean', where you at ?

Freight charges are a serious consideration on a whole disk's worth of blades. Make sure and compare cost of blades PLUS freight if ordering from out of town

If size needed is only avaible with the shipping then that has to be done and the size that disk calls for is not ready avaible most places. They only stock what should only be used on the big heavy wheel disks.

Most of the discs are in good shape on the disc I have. The outer disc on the front gang is beat up on mine.Freight is a big concern. Ordered one from agri supply. Disc $12.00 freight $21.00 Ordered one from the case international dealer here in, Burlington,Wa. state of Wash. $40.to store plus additional shipping to the San Juan Islands where my disc is located
