20 Pa.C.S. § 3354: Power given in governing instrument.

A testamentary power given in the governing instrument to sell, unless expressly restricted, shall include the power to sell at public or private sale or to pledge or mortgage for any purpose of administration or distribution, but shall not include the right to grant an option without court order. A private sale may be made, with court approval, under the provisions of this title, although the governing instrument has directed a public sale. A power in the governing instrument to sell, pledge, mortgage, lease, or exchange, or to grant an option for a purchase, lease, or exchange of property not given to any person by name or description shall be deemed to have been given to the personal representative and may be exercised without court approval. When the personal representative has been required to give bond, no proceeds of real estate shall be paid to him until the court has made an order excusing him from entering additional security or requiring additional security, and in the latter event, only after he has entered the additional security.
