Yep, they are clearly operating at idle.
The fertilizer truck arrived just as Elam finished.
The Elam went over the field again. Notice the two outside horses are black buggy horses. The colt on the left is in training, learning to pull in step and follow voice commands.
Then David and 4yo Amos are laying irrigation tubing and plastic. The pumpkin, watermelon, and cantaloupe plants that are growing in the greenhouse will be planted thru the plastic with a wagon wheel planter after last frost. The plants will be fed fertilized water thru the line under the plastic.
