That rear axle is rated for a 400 lb load on the 3PH. A 2" cylinder will apply up to 3100 lb of force against that lug in order to lift a 400 lb implement, depending on the geometry. A MF4850 tiller weighs 385 lb . . . without dirt hanging on it.
This is not good!
Thanks for the info, I will go easy on it for right now, I just need it to pull a plow for right now, I'll keep my box blade off of it for now.
I will look into moving the cylinder to another location
