I am doing maintenance on the planter for next spring ( only 4 months away, yikes! ). Some thoughts on which oil on the planter drive chains would be best, in your opinion. I have noticed in the past that sometimes a crust of dust builds on the chains and that makes them stiff. My idea would be some good penetrating oil that doesn't leave a stickiness. Is that possible? 

I will also do a search on here. Thanks
