Anybody know if both these gears (number 2 on the planter drive) are the same? I'm wanting to run my fertilize hopper with my planter trying to find the gear I need.
Most I see appear to be larger anybody have a part number or tooth count or size? Here's one tst has for sale it looks larger

They dont have to be the same. that is where you get your spacing on the planter and the amount of fertilizer on the side dresser. There is a gate on the hopper, but you can also change the gearing. I would read the manual if I were you. I could explain it all to you but that would teach you nothing.

If you look at all the planter manuals, you'll see that there are a couple different gears that were used on the final drive. I made myself a chart last year of what sprocket went where for each of the different setups. From what I've seen and recall, there is a base sprocket setup that the manuals use and a couple have charts of seed spacing with different sprocket combinations. The fertilizer charts are based on having a 15 tooth sprocket on the countershaft and fertilizer drive and two 9 tooth sprockets on the planter drive. If the inner was 9 and the outer was changed to say 12, you would be putting out more fertizer. I don't see the point in changing the ratio to the fertilizer drive because you have the adjusting lever. Planter? Yes definitely because you might be stuck with a playe that plants too close or too far apart.

Sometimes one might need a fertilizer rate that you can't get by simply adjusting the lever on the hopper.

When you change the gear on the seed drive, you change the speed of the drive gear on the fertilizer!!!
send me a pm if you need any more info and I will give you my phone #
