Having a problem with a 459 and a 450M round baler getting pin holes in hydraulic hoses from tractor to the tension control valve on baler. Any ideas as to what could be causing this to happen. Thanks in advance
 
Old hoses or been used when highly over heated from to hot of hydraulic system over heating the rubber in the hose. And last but not least leaving it set out year round will kill hoses fast as anything.
 

Common wire reinforced rubber hoses or the thermoplastic ones? Thermoplastic likes getting crushed or kinked less than rubber/wire hoses. I have seen them develop pin holes where they have been flexed a lot.
