You say you want an insignia for the farm, but how will it be used?
Sign at property entrance?
Business card?
Letterhead?
Vehicle lettering?

You mention that you already have a logo for the fabrication business and you also mention draft horses above.

The logo with the two line art pieces is confusing - do you have performance horses for jumping, performance horses for racing, performance cars, all of the above?

The overlapping shapes also will only work in two color where they are separated visually, it doesn't appear either of these would work as a one color print.

I think you would be better off using a single graphic, instead of forcing the two, or go in a different direction and play off the name for the graphic.
