Even if rsa is not there, the one rake of hte ltt sf will be idle from mon to fri, and other from tue to sat . I Hav never seen hte ltt rake standing in yard for that much time. Another rake of hte ypr will be idle from thursday to sunday and other from sat to tue. Its not possible. Its just like before all these 4 pairs 12817/18, 12873/74, 12811/12, 12835/36 share their rakes.
