Seed spreader with speed control?

I have a seed spreader that I've had for years with one speed but, I'm looking for something with variable speed. Anyone have one they like that control speed? Id like to be able to just seed my trails and not the brush. I thought about trying to add a speed dial to the one I have know but, I don't want to mess it up.

 

I have an old "Cyclone seeder" with a rheostat, but it's probably as old as I am.

 

Yep. I just crank faster or slower.

 

Same^^^^^^

Similar to the "glug -glug" method of mixing gly in sprayer

Yes Sir, the glug unit of measurement has long been accepted in my part of the world. Also the axiom "If one glug is good..........two glugs is better!
