I then came across this copy, which is probably identical to the Spreader of Hecht. It is equipped with large wheels (enough distance from the lawn), the scattered openings at the back. After initial use today, I had at the end but unfortunately find that the wing nut was missing at the pivot point of the control lever and was probably dropped. Happy the handyman in his quota has screws M6 nuts. The remaining thread was at least long enough for mother and locknut. The lever can now again with less play adjust. A scatter chart for common fertilizer is applied.
Conclusion: I'll keep him in spite of eye contact for any issue, since it has a good price / performance ratio and for my purposes (lawn fertilizers) only regard as suitable for use to twice a year. For coarse fertilizer (z. B. blue corn) certainly not robust enough and probably not recommended.
And do not forget check screws, possibly even replace wing nut by nut and lock nut! Therefore only 3 stars.
