3 Point Lower Bracket with or without Ears?

[That_cub_dude1847]

I'm looking to plow at least an acre and a half with my cub original. Engine is remade and is fully making the 7 horsepower it left with from the factory. Rear end is in great condition and there is no problem with it.

However, I would assume engaging in the ground with that much strain might rip the bolts and bottom bracket out of the rear end. Should I buy a bottom bracket with ears or will original equipment work just as good?

Also, for the lower bracket, should I replace the bolts with longer ones or will the original ones do just fine?

They have been furrow plowing with Cub Cadet cast iron rear ends for many years without issue.

Yes, mounting the lower bracket will require longer bolts, about 1/4".

Some of those threaded holes may be blind holes. If they are, too long a bolt can crack the case.

I think they are all blind holes
The parts look up calls for the right length bolts in the 3 point section.
1" W/O the 3 point (drawbar only) and 1.25 with the (inner) lower 3 point.
Add the outer lower 3 point, add another .25"=1.5"
Be safe, measure the depth to be sure.
You do not want to wreck the threads or bottom out the inside holes in the differential!

...with ears.
