I would get a few things, but keep the majority of it as reserve in case something breaks down during the season. If you are looking to expand, that means you will have more people relying on you and you will not have time for your equipment to be down. Therefore it's going to cost you to get it back up and running. Having money in the savings is not a bad thing.
