Until you repair Willy's boat and sail to the volcano mines, adding enchantments to your implements will not be an option. But you can still upgrade all your tools from regular (to copper to steel to gold) up to iridium quality in order to increase their efficiency and reduce the amount of energy required to use them. Once you've provided the money and metal bars to Clint the Blacksmith, it takes at least two days until he returns the implements.
It's unlikely that you'll have upgraded all your tools to their maximum potential by end of your first fall season since you'd have to do so in between tilling, having your sprinklers set up, planting seeds, mining for the required materials, chopping wood and so on. This makes winter the best season to upgrade tools you haven't leveled up yet since farming and clearing your land can be skipped completely
