Finish two big lawn projects at once with John Deere’s 40 in. Tow-Behind Aerator-Spreader.

The durable steel spreader hopper supports up to 100 lbs. of material and features calibrated flow control with adjustable stop features. The aerator’s 8 in. diameter galvanized steel tine stars resist rust and perforate the soil up to 2 inches. Multitasking has never been easier.

Rated 2.8 out of 5 by 18 reviewers.
Rated 1.0 out of 5.0 by Poorly designed with too much plastiic in stress areas weak plastic bushings at end of axle,drive chain has no way to tighten, chain cogs misalign after 1 use. chain jumps off. Plastic bushing at end of axle too weak. Plastic spacers between spike units too weak. I have a lot of John Deere equipment. This mess does not measure up to the quality expected on any John deere Product. Very,Very Disappointed. Will Return for refund. May 24, 2013
Rated 2.0 out of 5.0 by Standard features but designed poorly for operation. Metal deforms easily, tires poor quality. I found the spikes go out of alignment readily but are also easy to bend back into shape. The cheap metal channel that holds the lever that regulates the spreader opening deforms easily and the wing nut is not something you can change the setting for on the fly. The lever that raises and lowers the spikes is not easy to reach and change from your lawn tractor (and I am 6'5".) The tires went flat but don't seal properly against the rims so re-inflating is very difficult. May 18, 2012
Rated 1.0 out of 5.0 by It broke the first time I used it. I was very pleased to buy this item a week ago, but was quickly disappointed because it broke the first time I used it. Despite soft ground, careful speed, and putting two cinder blocks on it for weight (like the photo showed) the axle eventually bent in the middle, causing the chain to slip off and the spreader to stop working. The center metal support piece is thin metal that bend quite severely. I didn't hit anything like a rock, curb, etc. so I assume perhaps this accessory just wasn't up to moderately uneven ground. I think it was designed for a well-established and smooth "subdivision lawn." Took it right back to the JD dealer. Will see what the warranty covers or doesn't. I think they tried putting two functions in one device and ended up with a cheap piece of machinery. September 27, 2012
Rated 1.0 out of 5.0 by Missing part and did not put together correctly. One part was missing. It took two different days calling in order to get this part through a number of calls over a three day period. I would be direct from JD to another vender who, as I under stand, put all the parts in the box. They were never very helpfull. JD would not call them for me until the third day when I called (after trying to get them to call before) and told them I am the customer. Finally got the part. The other problem is that I believe other parts might be wrong for this. Some parts will not go together as I believe they should. I am considering returning this item, I just need to look up the procedure for doing this. These comments are breif and not the detail that actually happen, but just an overview. On the other hand, the la45 lawn mower is great! May 26, 2011
Rated 1.0 out of 5.0 by Bad parts Wheel assembly was improperly made. On assemblly, the wheel shafts were not parallel. Therefore, one wheel was higher or lower than the other by 25 degrees. Deere was quick to send another assembly, but it had the same defect. I am waiting for another part that I am assured is properly made. Quality control is questionable. June 25, 2011
Rated 1.0 out of 5.0 by Piece of junk Arrived missing bolts and nuts. First use sprocket and chain jumped off with seed paddle no longer operable. Poorly engineered. Piece of junk. I would like my 450 plus back September 29, 2014
Rated 5.0 out of 5.0 Nothing runs like a John Deere Another quality product by JD. The assembly instructions were a little vague but the spreader itself is great. Superior build quality. The spikes penetrate about 2"1/2 inches and drops your fertilizer or seed right behind. This thing will last forever. One of the best parts is the free shipping. A 90 lbs. huge box for free, I'll be shopping with Home Depot for anything over $250.00. Another prime example of, "You pay for what you get". May 15, 2010
Rated 5.0 out of 5.0 by John Deere Aerator-Spreader One of my best purchases I have made. I put the aerator-spreader together without any help. As I have only one good leg I could not bend nor kneel which would have made the experience much easier. It performed faultlessly and is an excellent buy. The instructions were easy to read and follow. I would recommend this equipment. July 24, 2010
