Cub 101A Fertilizer Unit

[bowevil]

I have a Cub 101A Fertilizer Unit, and I am looking for more information on it. I have seen the sow chart in the manual for this implement, but I am wondering what is the difference between slow speed sprocket and fast speed sprocket? I assume they are talking about changing the sprockets for the drive and driven, but which is which? Can anyone help with this? I know i can slow it down with a different feed wheel, but since I don't understand the difference between the slow and fast speed sprockets I don't understand which end of the spectrum I am in terms of which route I need to take (i.e. Would I be better off with a different feed wheel or can I get to the rate I need by changing sprocket settings?).

Thanks

G'day to you bowevil

First thing:

to Farmallcub.com Forum Family. And you have come to the right place for all things Cub related. If you click on the Site Rules, Regulations, & Important Information, it will point you to the Welcome Wagon wherein you will find links to many useful sites and topics. One of which is the Cub Manual Server. Enjoy!.

Here is the Cub-101A Fertilizer Unit Owner's Manual. And here is the Parts Breakdown for the Cub 101A Fertilizer Unit

I think that the differences are determined by the # of teeth on the sprockets. See Item #15.

There are multiple sprockets through that drive system that can be changed. If you are driving through a seed hopper drive, it can have an effect too. But the actual "slow speed sprocket and fast speed sprocket" is probably a reference to the sprockets at the fertilizer hopper. Slow usually has 15 teeth, fast has 7.
