Worth getting a tractor early because of promo or wait?

We close on a house end of March with 5 acres and are looking at sub-compact tractors to mow and do small animal and planting tasks. I am seeing a lot of special promos right now for 0% interest for 84 months(mahindra, kioti, kubota) and some brands even offering a free front loader until Feb 28th(kioti). Are there usually spring sales too or should I take advantage and just store the tractor at our rental for a month?

Also not convinced I shouldn't just buy used but 0% interest is appealing
