If there is a difference the Sears one will be thinner steel.
When you are under them all day you notice things like thicker paint over thinner steel
The hanger plate directly in front of you original crack needs a 3rd bolt positioned behind where your frame cracked to prevent flexing

They are the same frame It is just Power Mower is selling at list price. Plus it is the first time I have Sears to less on anything mower related. Matter of fact they are only $18 over my cost for the same part. But be aware of the shipping costs, before buying ask what they are. This is an oversized item.
