Adjustable furrow opener with spring-loaded wheel row

use the details below to give me the images the client needs in zip, be fast, it's just the images only, ignore all the other details but they should act as guidance, the images must be in a zip, the zip file is what we need to improve on. this is the client revision messange after I submitted the zip file: I don't understand this; the right half remains unchanged, and we are modifying the left side. I require that a spring be added at the location marked by the small red circle to enable a row of gears to move. these were the original files and instructions from the client, Then improvements are needed. The furrow opener on the left can be adjusted. Now you can see that this gear is indeed adjustable. Add a spring. Achieve adjustability This is adjustable. Remove the two middle columns. Connect the two sides to install this device. Achieve 3-level adjustment Adjust the burial depth. The function to be implemented is to allow this row of wheels to move up and down together in an adjustable manner. There needs to be a spring. Just design it however you see fit. and kindly, be fast the deadline is approaching, I do not have enough credits because I am using your free version so make sure you produce the files in this single response,
