Help to find scarifier and aerator for small lawn

Hi Everybody,

I am newbie to the forum and in the world of lawn care! My other half used to do it but I have decided to take over as I wanted to spend more time outdoors.

We have ro-lawn put up about 8 years ago. Its doing okay.

We were using rake and garden fork to aerate and remove the thatch. Just had a look online for prices to hire these tools. I think I will rather own these tools.

I would like some advice on which scarifier and aerator to get considering its a small lawn  ( size of 3 box rooms put together) . we have small shed to store tools.

Thank you in advance.
