I have leased cars in the past but never a tractor.
Now, is leasing just for business or write off or can it be OK for private use. YES
You have to go back to the purpose of leasing or why your considering leasing. No down payment or smaller down payment was one of the reasons on the past for people to lease. Also in the long ago past credit worthyness was also another reason for leasing cars/trucks. In the past there were also some benefits for companys to lease. Most of these reasons from the past have changed. Most car leases now require great credit, down payment in the very small fine print and accountability of business/personal use has to be documented so the personal (mostly) business vehicle has not much write off value if one is staying LEGAL.
OK back to tractor lease. With the 0% 60 months or even the longer terms with low interest rates will show very easily how much a monthly payment will be required to buy it over a specified term. If one gets the monthly payment of a lease over a specific term and then compares the 2 payments side by side will be able to see what the monthly cost is for owning at the end of the term or giving the machine back at the end of the term. Maintenance and repairs required during the lease term are usually the responsability of the individual that is using the equipment, not the dealer/Kubota.
I'm pretty skeptical as to a lease being a better deal at this time over buying it with 0$ down and 0% interest. That was one of the main keys to the benefit of leases in the past, the interest rates determined the monthly payment and sometimes leases were figured on lower interest rates which tipped them over the edge into being a better deal.
