WS4150 MAIN PIC-etched

A revolutionary T or + shaped blade for even higher productivity, the WS4150 is the ultimate solution for efficiently splitting small blocks. 

Built on a similar, but bigger frame than the WS3150, the WS4150 features a standard straight or T shaped (or optional + shaped) blade. With the 3 or 4 way blade, this machine has the potential to dramatically increase productivity by reducing the number blade cycles per timber block. The 18 hp engine delivers 26 tons of splitting force and a 6 second cycle time.  The WS4150 is fitted standard with a 200kg capacity log lifter, 1.5 m wide bench, robust construction & the innovative double handed control system. Other new additions include:

  • 3 Rollers in the bench and extra rollers in the log lifter for easy manoeuvring of blocked timber
  • Standard 18hp Vanguard engine – an upgrade from the existing 13/14 hp Vanguard
  • Offset blade: The operator is now closer to the elevator for quicker handling
  • More robust tabletop – 8mm steel
  • Two hand controls with single touch auto return and auto cut-out at the end of return stroke (knee return mechanism has been removed)
