Nishigaki Karitaro 400 Brush Cutter Attachment Baler N-833 Used

Used with a KIORITZ brush cutter. Used for only one season, but due to age, I couldn't manage the work at high places without strength for more than 15 minutes and gave up. I think it would be more efficient for someone with arm strength as it eliminates the need to climb up and down a ladder.
One sleeve accessory is missing, but it looks the same, so I believe a substitute can be used.
There is no instruction manual, but it seems you can find how to set it up online.
The shaft socket currently attached to the trimmer is for KIORITZ.
It cannot be used with electric brush cutters as it lacks the horsepower; only compatible with engine-powered models.
