Now that really sounds stupid as can be but they just hire order takers that have no idea of what they are doing. It is like A&I not being able to send a Briggs price file with the supersedes listed but Power Distributors can.
BTW I don't call them Dingbats; I call them Space Cadets as they think their panties are out of this world.
The part I quoted is off the Raptor 937813 mower which has the same frame. Just setup for 42"/52" deck as where yours is setup for the 48"/54"/60" deck It has the same cross support bar. As for no cross reference several OEMs started doing this just to confuse the heck out of us. That why I am keeping my own cross reference of PNs. So I am driving them crazy too. Like working on a JD or MTD and installing Husqvarna electrical parts
I found the part over on
https://www.smallenginesprodealer.com so it would have only a $5.95 shipping charge since it is $13.39 there.
