The general liens of landlords shall be inferior to liens for taxes and to the general and special liens of laborers but shall rank with other liens and with each other according to date, the date being from the time of levying a distress warrant. The special liens of landlords for rent shall date from the maturity of the crops on the lands rented unless otherwise agreed on but shall not be enforced by distress warrant until the rent is due, unless the tenant is removing his property, or when other legal process is being enforced against the crops, in which case the landlord may enforce the general and special liens.
