Back in the 80's my Dad had a Wheel Horse 308-8. I thought the entire
frame was Cast Iron, but found out the front axle is Cast Iron and the
frame is welded angle Iron.

The new lawn tractors today typically have 11 gauge Stampled Steel
frames.

Are the old Wheel Horse Angle Iron frames truly stronger?

If either would crack or break, which would hold up better when
welded?

Thanks,
Sam
