I have the Craftsman rer1000 30" riding mower. It is about 7 years old and was an early version with the MTD 420cc engine. It is able to pull this thing without a problem! That is running just off of idle too. Since my yard has already turned into a brick I just waited till the day after a rain... threw on four 4x8x12 concrete bricks on top and towed it. Good/full penetration in most spots. I had to use actual ratchet straps to hold the pile of bricks down. Those things were shimmying their way out on the first lap due to all of the rocks/roots/limbs/and erosion ruts. I just got a new home on an acre. The yard is a complete mud hole/compact clay. Soo... all of the contraction debris, and roots were occasionally fowling it up and I had to keep an eye on it. It was bouncing over the rocks and such no problem. No spikes bent. I just had to stop a half dozen times to pull out debris that was spiked and being dragged. I added grease to certain points during assembly. Can't hurt to longevity. I may modify the lever for the wheel fold though. It falls forward via gravity to lift the wheels and works well enough. Just got large chunks of wood that caught it and forced it past the holding/catch bold. I will likely put in a slightly longer bolt. Seems HD enough to last many years... and possibly decades for home use. Once I get the debris out of the yard and some grass growing. lol Those holes should allow water, air, fertilizer, and seed to fall in and grow. Later on it should help with the water, air, and fertilizer once I start building thatch/compost/soil. I like it!

The instructions were a little confusing, I think, and I ended up having to undo several steps to redo them. That could be clarified a LOT more! But once it was completed, using it was a cinch and it worked great! I used it on an afternoon when it had rained that morning, so the ground was still wet but not soggy. I put 2 cinder blocks on the support (no ties necessary), easily attached it to my mower, and ran it over the lawn several times. It aerated well with no problems at all. * Update: I bought this in 2020, and it's now late 2025. Aerator still works perfectly and I've never done any maintenance.

PROS, IT SAVED ME A LOT OF MONEY , OUTSTANDING PRODUCT, well built , does a great job of aerating my lawn , Cons , Requires assembly and tools and patience to assemble because of the way it was shipped to me. {sockets, ratchet, } 9/16 , 1/2, 5/8, same size with open end wrench , or adjustable wrench which takes longer , Once assembled it is well worth every dime . With the lawn service charges now a days This paid for itself 10 fold the first time I used it . Now I have a great looking lawn .Cheers Nick

Product assembly instructions have several errors... of which some personnel in their product support department are aware... others are not. First, the instructions indicate parts A thru N are shown full size... however part E is shown the proper diameter but the actual; part is 1 1/2 in rather than the 2 1/2 shown... since when you first assemble the rotating tines there is no compression on the springs it appears the actual part needs to as long as the drawing. Called product support and they apologized for defective parts and sent replacements which I received a few days later... of course, these were the same length. Called back, got a different person and she explained the drawing was wrong the slack would be taken up in a later step. Part M although shown correctly will be confusing to a person not used to reading prints... the view looks like a hex nut although just a washer... the two lines are dotted... would be better to show like part L. the views imply an X or Y marked on the hardware.... however, ends x and y on part 8 must be determined by bolt pattern and on part 9, Y is the one with the emblem. View 4a and 4b are also poorly illustrated since the tine orientation changes in each view. Views 8 and 9 are inconsistent with view 8showing 5 tines each to the left and right of part 7 whereas view 9 is correct with 6 tines to the left and 4 to the right. Finally, the installation of the tow bar is made difficult since the hole patterns on the tow bar do not match the illustration... and the fasteners must be installed in different size center holes. My point is a few sentences of explanation and correct illustrations would make this so much simpler. It indicates the manufacturer does not care how much extra time it takes the customer to assemble just as long as they save a few $ on printing proper manuals... in my business, we call that lack of customer focus a cardinal mistake. I have not yet used the device... the massive use of plastic in the rotating assembly scream upcoming issues... hopefully I am wrong

We retired and now have a small yard. Previously had large acreage and used a Aerway finetine aerator...they cost thousands and work very well. But in no way can justify such equipment now. But I do believe in trying to aerate your turf to assist in getting water and nutrients deeper into soil. This just penetrates the soil...the tines are like cutters and just penetrate...they do not move or rotate the soil. That's ok...it is a basic unit. Stack about a hundred pounds on it, wait for a rain or water your lawn and go out the next day and run it over your place. Keep it up and your lawn will look better. Can't say how long it will last, but it is built ok for a small place (for which it is intended). One person can assemble, but two would make it a bit easier.

UPDATE: Waited a LONG time on hold to speak with an AF customer service rep. yesterday, but when it was finally my turn, a friendly gal agreed a misplaced hole for a wheel bolt was a problem ("That's not gonna work") and put in an order for a replacement bracket in real time. Although she said that due to heavy volume it might take a day or two to ship, I got a shipping notice via email this morning. I'll still annoyed that a gross defect was missed, but I'm totally satisfied with Agri-Fab's customer service dept., so the number of stars is kicked up from 1 to 4. (Old text) Can't finish assembly - belatedly discovered a critical part (bracket for wheels) is defective: Pre-drilled hole is in the wrong place! NOT HAPPY.

I've read reviews on other aerators that said they were flimsy sheet metal--that is definitely not the case with this. The frame on this thing is really solid. The pieces under the most stress, such as where the axle connects, are heavy and look like they were cast. The pieces that hold the wheels are at least 1/4" thick, if not 3/8". They are definitely designed to hold the additional weight that you will strap to the top. I added a plywood "box" to the top to hold sand bags. They provide bolt holes for this, so no drilling was necessary. Assembly was tedious. I wouldn't say it was difficult, but it took a while. I recommend a pair of disposable gloves--the axle is pre-greased, and it's hard to put this together without handling it. As for the aeration itself, I only give that 4 stars. Other brands had spike wheels with steeper angles that probably dig a little deeper. But my biggest issue was the plastic pieces. The spikes each have a plastic bushing, and they are separated by plastic spacers. After my first use, I broke nearly all of the bushings and several of the spacers. These were replaced under warranty quickly and painlessly, but I don't know how many times they will do so. From now on, I will be careful not to turn sharply, as I think the sideways pressure is what broke these. I will give them this, though--the way they designed this, using springs to hold the spikes in place, means even with broken pieces it still mostly works. Good design. I'm mostly happy with this, but I wonder if it would be better with the metal spacers shown in the picture.
