I see in your profile you are getting it with a loader. Some thoughts I would have are:
When moving material with the loader, keep the load low to the ground and even when the loader is empty, keep the bucket low. That weight up high makes the tractor MUCH less stable.
You will probably want to get something to put on the 3 pt hitch to balance the weight of the loader when using it. I usually have my box blade on the back.
When you start getting multiple implements for the 3 pt hitch, you may want to consider some type of quick hitch. I use the Pats quick hitch system advertised on this site, but others have their favorite.
Assume this model has a system for removing the FEL similar to the US versions, it is pretty simple to take it off. I really only take mine off when I use the MMM to mow and that is to avoid hitting things such as the house with the FEL and since you have a dedicated mower, you might not do it much. But it is worth practicing so you know how to remove it and overcome the fear.
If it is like mine, there is a grease fitting where the HST pedals pivot under the floor board. It needs to be greased once in a while. If not, it will tend to stick in either the forward or reverse and may keep moving after you take your foot off. Also, it may cause the tractor not to start until you push on the pedals to center them.
Enjoy your tractor
