Vaccum brings up another question. I could start a thread on it but I'll just ask it.
I have a proline 22040 I have 2 of them. One seems to vaccum a lot more than than the other on the same rpm level. I just know this by one way. The bag flys up on one more and you can barley push the bag down. However on the other mower it just barley opens up and you can just push down on the bag and it might leave like a crease there.
When I say open up I am meaning how much air is getting in the bag causing it to rise. I have checked the opening on the mower but no luck.
