Disk Style Wood Chipper

Performance & Productivity

The J.P. Carlton Model 1790 wood chipper is the most versatile and powerful 9-inch disk style chipper available.

The 1790 is portable enough to be pulled by a light duty pick-up truck, yet powerful enough to fill even the largest chip trucks. It incorporates several J.P. Carlton exclusive features like dual lift cylinders, Imron paint, 32-cubic-inch infeed motors and integrated reversing autofeed. The 88 hp turbo diesel Kubota engine powers massive 10 1/2 x 16 1/4-inch feed rollers allowing the 1790 to easily chip 9-inch material continuously.

The J.P. Carlton 1790 wood chipper is built to withstand the punishment you dish out. From the heavy duty infeeders to the formed infeed, the J.P. Carlton 1790 is the most solidly constructed chipper on the market today. Thoughtful design elements like concealed wiring and full-length radiator protection guards keep the 1790 operating at peak performance from year to year. For DURABILITY and DEPENDABILITY nothing compares to J.P. Carlton.

  • LED Taillights mounted high on the infeed out of harms way. The 1790’s taillights have heavy duty covers. All the wiring runs inside the frame to give the machine a neater appearance and keep wires clear of damage.
  • Live Hydraulics run directly off the engine allowing the operator to engage all hydraulic functions without the disk being engaged.
  • Hand Crank Swivel Discharge Chute allows the operator to easily fill the truck corner to corner, or easily direct the chips to a precise place on the lot.
  • Hand Crank Height Adjustable Discharge Chute allows the operator to quickly adjust the discharge perfectly for any truck.
  • Heavy Duty 1 ½ ” Feeder Bar
  • 48″ Wide Feed Chute takes the big tops, requires less trimming by the crew!
  • 9″x 17″ Throat Opening, largest in its class, easily handles the most difficult materials.
  • In Frame Fuel and Hydraulic Tank ease maintenance and clean up design.
  • 88 HP Arborist Package Kubota Diesel, specifically designed for use on a chipper and includes: radiator debris screen, live hydraulic pump hook up, slanted top, locking side panels, easy access air cleaner mounted to the rear of the engine to keep it as far away from the dust as possible.
  • Heavy Duty Infeed Table and Folding Tray.
  • Locking Fuel and Hydraulic Tanks sit down in the frame for maximum capacity and a clean design.
