Will a 743 operate a tree shear? I bought a place in Texas that is festered with cedar trees( Junipers) that I would like to remove. Pushing the trees over lifts up all the rocks.
No reason why it won't, it has around 2,600 PSI of hydraulic pressure.
Newer machines have a little more, but higher flow for attachments that have spinny parts that need more power to do the job, like snow blowers or road profilers.
