What caused this? Have a guess

[arbwork]

Felled today 2 Norway Maple sited in a shrub bed next to a shopping centre, stump cut reasonably close to ground level. ( worth a mention in rate my hinge ? ) I think I know the reason for the marking.

cause - id say metal....hinge....i aint perfect but id say you were a little too high with the back cut, i always try to cut level or marginaly below so the hinge doesnt break too early...unless of course i want it to break e.g jump cut...

some kind of foreign body anyway at a guess. Yep back cut is too high but nice and level and straight:thumbup1:

If i want my hinge to break early i just close the gob a bit more, back cut is always the same.

Something from a tree stake maybe?

 

Having the back cut a little above the hinge is fine and what I aim for on most fells from the ground... why would you want it to jump from a cut made from the ground anyways?
