AX19 Brush Chipper

When it comes to power and productivity, the AX19 Vermeer brush chipper is designed with robust features to expand your job possibilities. Equipped with mechanical feeding capabilities and a 173-hp (123 kW) John Deere diesel engine, this unit will efficiently work in large land clearing operations or on a rural jobsite. The AX19 features up to 12,000 lb (5443.1 kg) of pull-in force with the support of the patented SmartCrush control system, allowing you to feed large-diameter logs or branchy limbs with minimal effort. With no two jobs alike, the AX19 is built to finish the challenge.

Features and benefits


  • The fixed infeed table design and oversized infeed opening gives the operator improved performance and durability when mechanically feeding.
  • Dual offset horizontal feed rollers lessens the need for the operator to manually control the machine when feeding large-diameter logs.
  • The AX19 comes standard with the Tree CommanderTM remote control, improving jobsite productivity by allowing the operator to control the functions of the brush chipper remotely. The remote control can be attached to the operator’s belt or held in an optional bracket mounted directly to the operator’s station of a Vermeer mini skid steer.
  • When equipped with the winch option, the winch can be operated with or without the boom in place, which is easily removed with just six bolts.  When removed it allows the operator to mechanically feed the chipper, without the winch structure interfering with the loading process.
  • See your Vermeer dealer for comprehensive service and genuine Vermeer replacement parts.
