I do not know in what year the SSQA standard (Skid Steer Quick Attach) was adopted by the tractor industry. The Kubota you are contemplating may or may not have SSQA, permitting one minute change from an FEL bucket to FEL pallet forks.
Inquire of the dealer about interchangeability between bucket and pallet forks generally. With clamp on (as opposed to SSQA) pallet forks, sooner or later a timber will roll over the bucket and over the tractor hood...... You are welcome to visit and see my hood dents. The incident did not kill me, but it could have.
