Question for anyone that has used either or both of these 3PH wood chippers.
Trying to decide between the two for use on a Massey 135, so in the sweet spot on the WC68 vs low end of the WC88. From combing through the specs, there are a few key differences that I am curious about .
- Flywheel: WC68 is 34" thick, WC88 is 1". Im thinking more weight = more inertia, so thats good.
- Flywheel Speed: WC68 direct drive off PTO @ 540 RPM, WC88 belt driven up to 1100 RPM.
- Knife Size: This is the one that stood out to me. The WC68 uses 4 knives spaced 90 degrees apart on the flywheel that are "full height", or they span most of the opening from the feed chute. The WC88 uses 4 knives also at 90 degrees, but they are half height, and are staggered, where one is on the outside edge of the flywheel, while one is closer to the center.
The knife thing makes me wonder if that would cause an issue where material might get fed before its able to be cut if it hits the "blank" spot, but then again the flywheel is spinning twice as fast so has the same amount of chances to take a bite assuming the feed rates are the same between the two machines.
I was leaning towards the larger machine for the bigger feed opening, and thinking the belt drive would help keep some shock load off of the tractors driveline a bit.
Any thoughts?
