Wallenstein BX72S vs Woodland Mills WC68: a 50-engine-hp floor or a 40-PTO-hp full-feed condition
BX72S and WC68 meet at the tractor size of the Kubota L5070 Premium: 50 gross hp and 39.8 PTO hp. That is exactly Wallenstein’s 50-engine-hp minimum for BX72S, and 0.2 hp short of the over-40-PTO-hp condition Woodland Mills gives for full 6-inch logs at full feed in WC68. BX72S is a larger dealer-sold gravity chipper; WC68 is a direct-sold hydraulic-feed chipper.
