I have some of those tractor blocks, I don't think it is garish, kids like bright colors. The print around the blocks has veggies so maybe use a farm scene in the other blocks or strips. John Deere tractors are used on farms so anything that represents farming or the colors you would think of when you think of a farm would work. I mixed mine with some fabric I found at Joanne's that belonged to a bugs line. It had lots of colors and they were in rows and reminded me or rows in a garden but they were kinda of cartoony for a toddler. It was weird but it worked and the child loves it.
