Patrol hedgetrimmer seems to have stuck motor or something

[Wobelaar]

Good day everyone!

My hedgetrimmer (Stiga SHP60) has some trouble starting lately. Normally when you pull on the pully to start the engine you kinda feel 'the bumps'.
Like there is that one point your engine needs to get pulled over everytime.
However, normally you don't really notice that point, but I've been feeling it lately very very much.
So you need to pull really really hard, and you feel it bumping.
Eventually it starts, but it really feels like you pull the whole thing apart when you need to start it...

Does anyone recognize what the problem is and how I could maybe fix the problem?

Thanks in advance!
P.s. English isn't my first language and they don't really teach us how to talk about gardening stuff in school, so please forgive me if my English has a few... or a lot of mistakes.

Check to make sure that the blades move freely and are not pinching or sticking...................................................................

Blades won't pinch until it is running. Sounds like partial seizure. Get it checked at your local machinery dealer. As it's a Stiga, it could be a write off
