Hi JohnRHR,
One thing I did not realize until I got one is that stand alone splitters generally use a 2 stage hydraulic pump. Basically two gear pumps running side by side. Mine has a 10 gpm and a 4 gpm so combined it pushes 14 gallons of hydraulic fluid a minute into the large 4.5” cylinder and it moves the wedge pretty fast. When it hits a knot or tight grain there is a pressure valve that shuts off the 10 gpm pump and all the engine’s effort is sent to the 4 gpm pump. This is described as “finding a lower gear” and gives you the best of both worlds, speed when resistance is low and increased force when needed.
I have a PTO pump for my backhoe and it only has one output. Perhaps it has plenty of power but the dual pump really works well. Absolutely add a log holder to one side too.
