Square/Round Disc Axle Question

MFan · Jan 3, 2018

I"d like to replace the front gangs on my Oliver 241 disc with 18 inch notched blades. I"ve checked the local farm stores and Shoup/Sloans and I have only been able to locate notched blades for 1-1/8 square axles, and my Oliver has 1-1/8 round axles. Can I run a disc with square holes on a round axle?

Yep,I do,have for years. Also have a 252 disk.15 ft.18-20" blades

I think as long you kept the gangs tight it would work

Sure can, no reson not to be able to.

Technically to help keep center of disc from cracking/breaking out one needs to keep rd &/or sq shafts tight.

I think that you would do well to bring a big socket, breaker bar and pipe with you the first time that you use it and plan on stopping frequently to tighten it.

Are you able to use the discs with centers for different size square shafts? Most of the discs available have square holes for 1 inch and 1-1/8 inch square shafts.

Kind of odd that there aren"t 1-1/8 round shaft notched discs readily available.

To prevent failure/wear of a bolted joint, the clamp load needs to be greater than the loads seen in service. In the case of square discs on a square axle the axle still needs to be tightened to prevent movement of the discs on the axle. You should be fine just make sure the axle is properly torqued to prevent movement.

I try to always use a 1 1/8 hole.Square or round.The square hole just contacts the ronnd at the flats.I,m quite sure there are even a 1 1/4" hole blade there in a place or two.....However the key is to keep the gang bolt TIGHT. like a 4 ft cheater pipe.Shoup sells a 'dura tight' spring washer.They work. However 1 1/4 " hole is the smallest. doesn't hurt a thing.However,I'm sure you are not dragging it over hundreds of acres,only a few. No worries.I drag my 15" over 200 or so acres every year.

IF you have the threads left on the axle after you've gotten the blades TIGHT, id put a lock washer and another onto the shaft and tighten that one down also.

properly torqued is the key.. My 1" impact will break the spools..

And just as in checking load binders after a few miles as we all know we need to do, we know that stress of being pulled can pull one of those discs off a grain of sand on the spool next to it, and suddenly everything is getting loose.

Unless and even if they are all new parts thake them to a wire wheel and pollish them up as just even a spot of paint on new can do that.
