I'm fairly new to tractors etc but......an old timer stopped by and the first thing he said was, you wanna sell your 4 in 1?
He also told me when I got it I would never take it off. Close, sometimes I must use the forks.
His best tip to me was, do not horse shoe the bottom edge. By that he meant when picking up something like a large rock, try to use the edges of the 4 in 1 vs picking it up in the middle.
He said my tractor could apply enough hydraulic pressure to bend the bottom edge, making the 4 in 1 almost useless.
That's advice from an old timer channeled thru a carolina noob.
