There are options for financing and some of them are quite good. Most of the deferred payment programs seam to make more sense to me because you can use someone elses money initially (without making payments) while generating income with the mower.
I generally recommend financing through one of the finance partners or a local bank that you already have a relationship with. Interest rates are low enough locally it probably makes more sense to use their money than to use your own. Some of our deferred payments may have a higher rate but there are still advantages to deferring the payments in many cases.
You may also want to look at leasing. Leasing may have some significant tax benefits to you. You may want to talk your accountant regarding the details.
