Have I damaged my raw ride on lawn mower??

Yesterday whilst cutting my lawn for the first time with my new husqvarna ride on I struck a long thin iron bar which was nicely hidden in the grass.

This gave a big jolt to the mower which caused it to stop. On inspection the iron pole had been bent a bit and two circular parts had also been detached from the underside of the mower.

The mower worked away after and I was able to complete the cut however I'm concerned that I may have done more damage that might cause me bother down the line

Could anybody tell me what the 2 circular parts that were detached may be or whether the blades could be damaged (despite being able to complete the cut) Any advice would be hugely appreciated
