Robust scarifier & aerator. Great piece of kit
Used this to remove the moss and thatch that has taken over the front lawn. The lawn is approx 70ft long by 30ft wide so a square area of 210ft. It dealt with this with no problem whatsoever. The motor wasnt getting hot at all. It got about 8 large bin bags compressed down hard. The garden looked like the Somme after but grass is healthier than ever 2 months down the line.Ive not used the aerator yet so cant comment but it looks the part.Criticisms.1.The appliance arrived with the aerator fitted., so I had to swap it to the rake. This isn't easy to do. The process is simple - just undo a couple of screws - but detaching the aerator was difficult and pulling it off the mountings not easy. Refitting the rake was easier once a little oil was used.2. The collector bag was really worse than useless. It simply didn't fill properly. This was the real minus on this.Overall I would give this 8/10. It would have been 9/10 but for the collector bag. It's a sturdy, large, robust piece of kit. The price made it an absolute bargain. I would definitely recommend you to buy this .....but be prepared to deal with that awful collector bag.

Pretty good
I've only just given this scarifier a test run and it seems really good. Assembly wasn't too difficult, and it is really light, which makes it easy to carry and operate. I agree with other comments that the bag is too small and fills up rapidly. I would have given it five stars if the bag were of more use. Best to rake up the moss. A good purchase. Time will tell if it improves my ailing lawn.

Scarifier
Very prompt delivery infact next day. Very light equipment but not lacking on power at all . I have a medium sized front lawn and large back lawn. Removed so much moss and dead grass on first use only downside is I believe the collection bag is slightly too small. Great bit of machinery.

Good machine but ineffective grass collection
Pro - mean looking and substantial machine. Good weight and easy to manoeuvre. The motor sounds a bit whimpy but it does its job. Not noisy.Con -rotorvator scratches the surface. Biggest con is the small grass box. It does not hold much and has no secondary floor to compress the arisings. It is also set too far back from the rotor - as a consequence grass builds up in front of the box resulting in a substantial clean up each time the box is near to filling.

Fantastic bit of kit
I never usually have the time or need to post a review. I do so if I have something to grumble about or warn people off of a product. However - I actually logged into Amazon today to leave this review because the product was worth the effort (and I have the time).Just for the record - I am not affiliated with or sponsored to leave any guest posts. That is not the world I come from (I work in IT).I'm no gardener or landscaper but having moved to a new property with a larger garden...I had to start new projects and learn how to improve things for myself and my family. Moss was a big issue with the lawn and a scarifier was on the list. Having read numerous reviews I settled on the Chinese made Einhall (german) scarifier and rake. Putting it together was very simple (20 mins) and then being quite lightweight I carried it with the simple handle on top to the worst affected areas of the lawn - plugged in the extension lead to my plug and got to work. The attached photo is my halfway point and it took a fair amount of raking to pile this lot up. With some new grass seeding and water, this area is already looking revitalized. It is by far one of my best purchases on Amazon.

Excellent Device for the Money
Excellent machine, for a lawn that was probably 75-100% moss in places it saved me tens of hours of work compared to manual raking. It immediately makes the lawn look terrible, but its a necessary step and now after seeding, feeding and sun and lots of water it is starting to look great.Minus 1 star because the bag is totally pointless, unless you only have 3 grams of moss in your entire lawn and also the aerator cylinder is not great - it is particularly bad on dry lawns as it just scores the top layer which effectively creates lines of dust that blow away, I might try it on a damp lawn and see if there is a difference. However, unless you are actually removing some content from your lawn your aeration will be limited - I will be buying a hollow tine aerator from Swardman.

What a beast!
Mine arrived with a 12m cable pre-installed whereas the illustrations show a plug connector just below the handlebar. I couldn't find any mention of the cable in the description.The scarifier blades were also pre-installed and the machine was soon assembled ready for use. My lawns of about 180 sq.mt are in reasonable condition with no more moss than one would expect at the beginning of the season. The scarifier was easy to use and so efficient that the box had to be emptied every 5 to 6 metres. I haven't tried the aerator tines yet but they, too, look to be very efficient.The machine is sturdy, well made and I could not be more pleased with the purchase.
