Product Overview

The TA-40JD, more commonly known as the Thatcherator, is built with an 11 gauge steel weight tray for adding up to 100 lbs. of additional weight. Innovation at its finest, by locking down the spring tines into the aggressive mode, you gently aerate the very top layer of your lawn's soil, while lifting out thatch all at the same time. Use to help prepare bare spots for seeding. In transport mode, the rib-tread wheels allow for crossing paved areas without damaging the tines or scratching the pavement. Tines come pre-assembled to the tray to decrease assembly time and are secured via safety wires to prevent damage to mower blades in the unlikely event of a breakage.
  • Assembled dimension: 40 in. W x 41 in. D x 39 in. H
  • 2 rows (20) of independently flexing dual tine tips for maximum thatch pick-up
  • Wheels are offset behind tray to minimize overall width and facilitate leveling
  • Tines are secured by safety wires; tray designed to allow for added weight
  • 40 in. working width

40 inch Thatcher
Works great for dethatching my 4 acres. My only complaint is the position handle wants to jump to the lowest setting. I used a spring clamp to solve.

Do not hesitate to buy!
Worth every penny. Top notch quality, steel is thick, paint is heavy and durable, Comes with a retained hitch pin and cotter pin so you don’t lose them (I didn’t attach it as I have the JD magnetic pin on the way), the wheels are actually no-flat rubber with a metal hub, not plastic push mower wheels like it may look, and like what competitors look to have. Quite a bit of weight by itself, which is something I didn’t expect. some real quality here. Not sure about some people on these reviews. I read a lot of the reviews and it seems like a ton of people said this is the hardest thing they have ever put together, and it took them the better part of 1.5-2hrs, and that the instructions were impossible... I saw no problem at all, had it assembled in less than 1/2 hour, it was a breeze... I think some people need to go back to 2nd grade and relearn how to follow instructions. Anyway; this is a must buy if in the market for a dethatcher, especially if your mower is a Deere!

    Very well made. I needed to make a slight adjustment to the pin in the handle so it better engages the raising and lowering plate, but overall very happy with the product.

    The product worked well on our yard even without weights. Others have commented on the assembly instructions. I found them to be the worst I've ever had to follow. And the photos were of little help; they looked like silhouettes. The pictures in the French-language instructions were much better and would have been much more useful, had I seen them in time. I was also confused on what to tighten when, and how much. We used the mower and bagger afterward to clean the thatch.

      JD Thatcher is great
      This product is extremely well built and definitely worth the price of just over $200. I use it with about 50lbs of weight (2 concrete blocks - see photos) and it works great. It took me 1 hour and 56 minutes to assemble and another 15 to 20 minutes to make the tine height adjustments. I have attached photos in the "transport" mode and the "thatching" mode. The only criticism I have are the less that clear assembly instructions. I recommend you measure the bolts and read the instructions carefully as you assemble it. DO NOT go solely by the pictures, because they often have the left and right mixed up. As someone else has pointed out the written instructions are very accurate. The pictures are often the wrong image. All in all Home Depot and John Deere have hit another home run.

            Assembly of the John Deere 40-inch tow behind thatcherator was interesting but not impossible. The build quality is definitely better than most I've seen and is made of thick steel instead of thin sheet metal. I have not had an opportunity to use it yet, but have a D110 I've attached it to for sizing and due to the low deck plate the rear set of tines is an inch or two off the ground. I may need to research a device that will raise the attachment point to the mower so the two rows of tines are level to the ground.

              Went together without too much extra work. Seems to work well enough. Is heavier built the others I looked at when I ordered this one.
