The 1990XP is equipped with the same powerful hydraulic feed system that is utilized on our model 1850 whole tree chipper. The top feed wheel is chain driven and is 15-3/4 inch diameter by 32 inch long. The bottom wheel is 10-5/8 inch in diameter by 32 inch long. Both are powered by 63.9 cubic inch hydraulic motors. The 1990XP has an extremely powerful chip throwing discharge system allowing it to fully load end opening chip vans and is even known to load trailers up to 45 feet long.

The patented power slot, adjustable side air flow vents, and side fan blades all enhance the throwing power of this unit. The patented power slot is positioned on the back side of the drum housing increases air flow and all but eliminates the chance of plugging. On the rare occurrence where the chipper might plug, chips are easily removed through this slot.

The 1990XP is equipped with a 41 inch high x 64 inch wide, wide profile heavy-duty infeed hopper with 30 inch fold down infeed tray. A solid infeed tray with heavy-duty rim is available as an option and provides an excellent means for folding limbs and material with numerous branches.

Another popular option for the 1990XP is a knuckle boom loader. The loader significantly reduces the amount of work required to feed this unit by reducing trimming material into smaller pieces in order to hand feed the unit. The loader will easily pull whole trees or piles of brush into the feed system. All loader functions are controlled on a swing-out operator's console with joystick controls.
