Hi sammy.boi84,

The 20 inch twin rail design SB 45 is rather a problematic machine as it normally suffers from cracked rails due to it's wider span opposed to the 14 and 17 inch machines.

The first thing you need to do is examine very closely around the engine mounting area on the rails and check for lines in the paintwork. If you have any showing then the machine becomes an instant strip down and repair before it gets worse and has dire consequences on the rest of the chassis and also the cutter clutch.

Can you provide some close up photos around the area mentioned after wiping all the dirt and oil away.

Cheers,
BB
