Hello to the forum, my father has an old Agria 9200 381 lawn mower. He always takes it in the meadow. I don’t know if anyone can help me. Now I have the following problem, I wanted to change the camp from the knife, which is sitting in the protective pot. But in order to be able to remove the camp from the protective pot, the knife taker hub must be pulled from the shaft coming from the engine. I tried it with a puller, no chance, that is so stuck. Then I tried the Mes The protective pot has such small oval openings (6 pieces) so I actually wanted to go with the puller at the top directly to the knife lifter hub to have a better attack point. Unfortunately, this does not fit, so I had to always put on the bottom, right there to the small flange of the knife lifter hub where you screw the knife and where the two small clamping sleeves are located. I have a small la nge screw put into the hole of the motor shaft, since then the puller is set and the jaws from the puller then to the lower flange of the knife lifter hub. The protective pot with the bearing (seen from below) is freely movable, can push it 1-2 cm up and down, after having loosened the 4 screws, which holds the protective pot and at the same time the motor on the housing. Does anyone have an idea? How could I do that or if I do something wrong and have a thought error? I have added 3 pictures for your better understanding. I would be grateful for your help.
