A "chattel" repossession (personal property, equipment, etc.) must be made without causing a "breach of the peace" (meaning no threat of physical violence). Otherwise, the sheriff/police can be called, and the repo personnel arrested.
So, if you lock your doors and refuse to permit entry, then the company must generally get a court order for a writ of attachment by the sheriff, so that no breach of the peace can occur -- which takes time and costs money.
Assuming that this were to occur, you could purchase a "redelivery bond" which permits you to retain the property until the lawsuit claiming the property in default is complete -- which takes more time.
And, you could file a Chapter 11 bankruptcy, which would give you even more time, but could get pretty expensive. Though, it may be worth it to you to contact a business bankruptcy lawyer to see whether it's worth the cost.
That about covers it. For a bankruptcy attorney referral, see: http://www.abanet.org/legalservices/lris/directory/main.cfm?id=MT and www.martindale.com.
Hope this helps.
