I am a retired Drill Sergeant. Why are you shouting?
I just not seeing horses pushing wagons and carriages around town, yet. Probably because pushing a rope and a chain makes less sense than pulling it. I'm only seeing mowers, brooms and plows in front locations. Only because users want to avoid trampling the material.
A std 3pt and PTO is a nice solution,
I believe most of these front PTO are 1000rpm.
