Where does the brake tension spring attach

"google the model number of your mower (its likely written somewhere under the seat if nowhere else) there are generally manuals online that might have a picture to show you where that spring belongs. In general though, pick a place that it functions correctly and you'll be ok. belts on a lawn mower are far from rocket science. Mine is currently rigged with a trampoline spring and fencing wire.

You need enough tension to keep it from slipping while engaged, but enough play that the clutch can get the pulley clear of the belt."

where does the tenion spring attatch because when i push the peddle for forward or reverse the mower want move.

My spring only fell off from one end. The other end was still attached to the frame. Does anyone know where the other end goes? Attach to clutch?

to help others it goes on the very back of lawn mower.
