Grooming rather than scarificateur

The concept is good, but do not expect a result of scarifying. This is rather a "surface toilletage" your lawn. I wanted to use (wet grass / October 26, 2013) without prior mowing, the result was not good because too much material (grass + foam + foil) extracted. So I mowed my lawn, then I pass this blade. 1 adjustment too low on "hard" while (yes scarifier with a parallel movement in the ground has the speed of an AC mower blade does not work). 2nd tuning "a cut above" and OK leger toilletage 50% grass, 50% foam but is left. We should have an intermediate adjustment (thus making a hole in the casing of my lawnmower, but I think I also see other solutions to an intermediate adjustment ...). I also think that its use regular frequency (1 per month) could also be beneficial ...?

Mounting the blade is OK (one of three spacers used to adapt). The mounting of the teeth on the blade spring is simple, even if the product does not match his picture because only one position (instead of 4) is available, which is unfortunate because the Right and Left teeth are therefore on the same radius and therefore pass the same place.

In addition, the blade has a "projection" of the teeth down to compensate for the presence of the teeth of the retaining screws (and avoid contact with the mower), but this is unnecessary because the mower axes are always longer. In addition, the shape of the blade length + teeth require to mount the cutting height to maximum, so more function "Pickup", everything goes on the sides and underneath the machine ...

After 1 hour of use, the legs that carry the teeth already distorted ....

At 60 euros it is rather on an expensive, but its design is as it was "low cost" unnecessary deport, legs wearing too thin teeth, over collection, only one available length whatever the size of the mower (for against they have not forgotten the cost of reduction of gait by removing radial adjustment holes teeth but is detrimental to the user).

The idea is quite sound, but the product Lack of outcome (the test campaign had to be very fast ...).
For DIYers: buy spare teeth (a half price), an old blade, some shots angle grinder, 2 holes, 2 bolts and voila.

For my part, I will modify the product to correct the defects cited rained up (drill a hole more to change the radius of a tooth in order to decaler radius work, remove the blade deport in flattening and the working height equal the intermediate adjustment of cutting height was missing, strengthen the support legs twisted view even modify them to further lower the working height hoping regain the "mopping up" function, if I must pierce the cover of my mower for a finer adjustment of the working height as this may well be a factor on the quality of the work ... ???
