I push EVERYTHING through the 4-way on my Timber Wolf, stringy crotches and all,
I leave it on 100% of the time and I think TW has the best designed, strongest 4-way going.
As for the wedge on the ram, getting rid of the splitters I had designed that way was one of my best ideas I've had. Having the wedge on the end of the beam makes splitting faster and less work for the operator, less handling of the wood is what it's all about!
Here I'm letting the splitter push the splits right into my "self unloading" trailer,
Even if we just push them into a pile like this,
it's less work!
Sometimes I push the splits into half cord boxes that I build,
It's just plain less work to have the wedge on the beam.
