Wallenstein BX72S vs WoodMaxx MX-8800: gravity feed or hydrostatic feed for a large compact tractor
BX72S and MX-8800 both suit a large compact like the John Deere 4075R (60 PTO hp, 74.3 gross hp). BX72S is inside its 50–85 engine-hp range; MX-8800 starts at 20 PTO hp and reaches its full 8-inch line at “50+ HP”. The choice is about feed and size: BX72S is a 7-inch gravity chipper, MX-8800 an 8-inch chipper with an operator-controlled hydrostatic feed.

Consider BX72S for a simple gravity chipperShortlist BX72S when the tractor is inside 50–85 engine hp, material is up to 7 inches and a dealer-sold gravity chipper suits the work.
Consider MX-8800 for feed control and 8-inch materialShortlist MX-8800 when an operator-controlled feed and 8-inch capacity matter and the tractor clears 50 hp for full capacity.

The differences that matter.
01
Engine 50–85 against PTO 20 and up
Wallenstein labels BX72S’s 50–85 hp as engine horsepower. WoodMaxx lists MX-8800 from 20 PTO hp and ties full 8-inch capacity to “50+ HP” without a basis.
A tractor with 60 PTO and 74 engine hp is inside BX72S and at MX-8800’s full-capacity line on either reading.
BX72S mounting is Category I and II on the current page and Category I only in the January 2025 manual.
MX-8800’s page says factory oil is included, while its manual assembly instructs an initial two-quart fill.
This comparison reuses the manufacturer evidence retained in the product records reviewed November 7, 2026; product pages were not re-fetched on November 9. BX72S uses the current U.S. page and January 2025 BX-S manual; MX-8800 uses the current page and Rev D manual.
