Well Uncle Ho, tell that to the bent post hole digger at the farm from it picking up the tractor and nearly killing me when the post hole digger stopped and the tractor didnt.
The shear pins eventually sheared when the fergie was on it's side with me still on it.
I didnt say it wasnt powerful enough I said it wasnt big enough I though but I will check .
18.5 rated HP at the PTO isnt that much in this day and age as well as they are a fairly top heavy tractor.
Ours is still up there, now on blocks in the shed but fit a battery and away it will go and I win as our farm was 640 acres when I lived there, now 420 acres due to my old mans superanuation paddock was sold but at 1 stage it was around the 1200 acre mark but half was bush land.
It was split up between other family members a generation before me but still mostly in the family.
To be safe the TEA 20 is a bit on the light side and under powered, over geared and a little on the narrow side.
Now im talking from experience in a heavy clay soil with rock about 12 to 14" under the surface, if it were sandy soil I would think different.
Unless their Grey fergie looked kind of like one of these then they will deffinatly have all the HP they want but these ones were blamed for quite a few deaths from roll overs and the like caused in many cases from tieing chains too high on the 3PL when pulling things but they were still safer to use than a fordson major or a Lanz Bulldog.
