i always seem to scratch my head when it comes to tractor mounted log splitters.
it is the larger rounds, and picking them up / bending over, and getting them into the log splitter.
many folks like to use pallets, cut -> splilt -> stack on pallets -> move with 3pt hitch forks. or if tractor strong enough move them with FEL forks.
a big portion of a tree is all the smaller limbs, and ya just kinda zap zap zap your way down the branches. and go back and pickup the pieces, or cut long hopefully not to heavy to pull over to an area to cut, but that kinda gets to be a hassle moving longer branches around.
once ya get the smaller branches down... ya end up at the trunk, were the splitter comes into play. and ya either skid / drag the now more or less log out of were ever and cut it up, or cut it up were it lays.
there is the occasional larger piece that gets through... nice to be able to toss to the side, and then hook up splitter to truck and haul it over to area. and split up the bigger pieces that ended up being stacked.
a grappel for FEL = nice way to clean up all the scrub brush (leaf's small twigs) to deal with. and take to some better burn spot. or ya load it up on a trailer and haul the little twigs some place else.
less amount of times you have to man handle the lumber the better... figure out a setup that works much easier for you. pickup truck, hookup to a log splitter for those smaller jobs? or?
what is going to allow you to lift those heavier bigger rounds into the log splitter and get them split? vs taking a few more chain saw whacks, to cut the rounds up much shorter than you would like?
=========
a backhoe with an upside down log splitter on it (instead of a bucket) could be rather handy. just split the logs were they were cut / lay. if not enough room to get splitter onto a log, use the end of the log splitter, as a finger to push the rounds here or there so you can get the splitter down on the rounds.
