Six chippers here fit the SA223’s power. WC46 is the heaviest at 587 lb against a 660-lb lift at 24 inches; the others are 346–430 lb. The comparison below sets WC46 against Farmry’s WCAP5.
Yanmar lists the SA Series hitch as Limited Category 1. Confirm lift height, lower-link spacing and PTO shaft angle with the chipper maker before ordering.
Woodland Mills ties WC46’s full 4-inch capacity to over 20 PTO hp. At 15.6, expect to feed the largest pieces slowly.
The SA325 and SA425 (18.1 PTO hp, 23.9 gross, 1,209-lb lift) clear Wallenstein BX52S and leave room on weight.
THE SCREEN, WITH ITS LIMITS VISIBLE
No pairing below is manufacturer-confirmed. “Preliminary” still requires implement limits, load center, ballast, hitch geometry and shaft checks.
