1st of all welcome to The Lawn Forum From France wowwww.
I dont think you problem is your mower. I used a manuel reel mower for 1 1/2 years and my lawn was great.
have you adjusted the bedknife to reel. Will it cut paper down the length of the bedknife. You can backlap alot of manuel reels. I have done it. but is is not fun.
What is your HOC ( height of cut)
How often to you mow your lawn?
Very nice.

It is absolutely possible to mow all seed heads with a manual reel mower. I have done it many many times.
Your problem is your mower.
Its an expensive piece of crap. With all reel mowers you should be able to adjust the reel too bed knife. If its not cutting paper and you cant adjust it then reel to bed knife then that is your problem.
You will always get seed heads in your Bermuda if you are only cutting once a week.
I have tried many manual mowers and I found the best being the American Standard or Great States manuel reel mowers

These can cut below 1/2 inch HOC can be back lapped your self and you can adjust the reel to bed knife easily. You are supposed to check reel to bed knife before you cut everyday. Make sure you can not adjust it on your existing mower. That does NOT sound right.
