Yes, most tractors are shipping with a standard skid steer type tool carrier (commonly called skid steer quick attach and abbreviated SSQA). This is the type that has two handles behind the bucket on the loader, turn them 45 degrees so they point up, and the bucket (or whatever tool is attached) comes loose for an easy change. Tip it down, set it down, back away. These types of loaders are made with standardized connecting points so any bucket or attachment made for SSQA works on any machine with a SSQA tool carrier on it. Most front end loaders on most brands of tractors have began to move to the SSQA system. Your ML245 loader on your 4530 should have SSQA tool compatibility, so any SSQA bucket will work on it.
Use care when picking out a bucket and keep in mind the uses you have for it. I know a guy with an older tractor and old FEL and when his bucket was shot, he thought it was a great idea to add SSQA to his machine (he had a older blown skid steer for a parts machine). He also thought getting a higher capacity bucket was a good idea because he generally moved around lightweight stuff. Between the additional weight of the SSQA, and the additional weight of the high capacity bucket, it ruined the lift capability. For his primary needs it worked fine, but he ended up having to get a smaller bucket for heavy uses and still lost about 300# of lift capacity due to the additional steel of the SSQA.
