Hooking implements together to save fuel.

What, if any, are some of the implements you have used in tandem to save fuel?

One combination that worked for me was----
I had deep Vee fertilizer tanks on my tractor and would apply liquid fertilizer while discing. I had sectional booms on the front of my disc and it worked well. I also incorporated herbicides with a shallow discing. (Late 1970s and very early 1980s.)

My father and I also used to like to do a final tillage right before drilling wheat.

One day I hooked the grain drill right on behind the disc. This allowed me to fertilize, disc, and drill at the same time. The drill was close enough to the size of the disc that I only overlapped about 6 additional inches. When I turned a corner the disc would actually kind of pivot in one spot and would pull the drill up into a tighter corner than when pulling it with a just a tractor.

Success. What have been yours?

Now I just make hay. I put a hitch on the back of the pinwheel rake so I can pull my old Grimm wheeldriven tedder/fluffer behind. I turn the windrow with two wheels the second day and ted it in the same trip.

No harder than a drill pulls, or a disc pulls on the final pass of the season, I really expect that a person would save quite a bit of fuel.

There was a campaign years ago, "Gear up, throttle down". At least when you can as the saying went. Wonder what ever became of it?

Sounds like some other good ideas here too.
