Wallenstein BX36S vs Farmer-Helper FH-BX42: small gravity-feed chippers
Both use gravity or pinch-and-pull feeding rather than a powered hydraulic roller. The useful differences are the power rating to check, the opening through which the brush must pass, and the space the chipper occupies when stored. BX36S has a fixed hopper; FH-BX42 folds its hopper, but its manuals and product page disagree on several specifications.

Consider BX36S for the engine-rated small-tractor optionShortlist BX36S when the tractor is within its 12–30 engine-hp band, the 3.5-inch rating suits the material and a fixed hopper fits the available space.
Consider FH-BX42 when folded storage mattersShortlist FH-BX42 when a folding hopper and the documented 4 × 10-inch feed opening answer a real handling or storage need.

The differences that matter.
01
Compare the correct tractor power rating
BX36S: 12–30 engine hp on the official U.S. page. FH-BX42: 15–45 PTO hp in the current index-linked manual; its product page instead says 16–50 HP without a basis.
A tractor’s engine rating and PTO rating answer different checks. Do not rank these minimums as though they measured the same output, and have Betstco confirm the applicable limits for the delivered unit.
BX36S: 3.5-inch published chip diameter, 3.5 × 9-inch housing opening and 13 × 20-inch hopper mouth. FH-BX42: 4 × 10-inch material feed capacity; current manual hopper mouth is 21 × 21 inches, while the page says 20 × 20.
For branched brush, measure the shape as well as the trunk diameter. The long side of a rectangular opening is not a round-log rating, and neither minimum-power figure proves maximum-diameter performance.
BX36S: fixed hopper and a published 55 × 45 × 60-inch open envelope; folded dimensions are not offered. FH-BX42: 40 × 42 × 60 inches with its hopper folded.
FH-BX42’s folding arrangement is a concrete reason to examine it for limited storage. Compare the listed stored states, then check clearance with the shaft and any transport stand in the intended position.
BX36S manual explicitly documents 540 or 1,000 rpm. FH-BX42 specifies 540 rpm. Both are direct PTO-driven designs.
For a 540-rpm tractor both have a documented speed, but that does not establish shaft fit. For a 1,000-rpm installation, confirm a BX36S-specific driveline configuration; the page’s range notation does not approve intermediate speeds or the supplied shaft at every speed.
BX36S lists Category I, iMatch and quick-hitch compatibility, plus an adjustable ski base. FH-BX42 lists Category I and an included 04-series, 30-inch shear-protected shaft; the reviewed model sources do not establish an equivalent quick-hitch package.
A quick-hitch user should compare the actual mounting and shaft setup, not just Category I labels. Ask for the required pins, adapters and measured shaft geometry rather than assuming the included driveline solves the installation.
BX36S is listed at 395 lb without a clear shaft-inclusive operating basis. FH-BX42 manual lists 430 lb net and 450 lb shipping; its page lists 423 lb net and 458 lb shipping.
Use these as questions for an assembled-load and unloading quote. Do not select a tractor pairing by treating net, total and shipping weight as interchangeable.
Consider BX36S for the engine-rated small-tractor option
Shortlist BX36S when the tractor is within its 12–30 engine-hp band, the 3.5-inch rating suits the material and a fixed hopper fits the available space. Its stated quick-hitch compatibility is useful to investigate, with exact shaft, speed configuration and operating load still to confirm.
Shortlist FH-BX42 when a folding hopper and the documented 4 × 10-inch feed opening answer a real handling or storage need. First have Betstco reconcile the 15–45 PTO-hp manual with the 16–50 HP page and identify the correct manual for the delivered machine.
FH-BX42 current manual: 15–45 PTO hp. Product page: 16–50 HP without basis. Older product-linked manual: 15 PTO hp for 3-inch material, 26 PTO hp for maximum capacity and a separate generic 15–50 HP range. The full-capacity condition is not an upper tractor-power limit.
FH-BX42 current manual gives a 21 × 21-inch hopper and 430/450-lb net/shipping references; the page gives 20 × 20 inches and 423/458 lb.
BX36S table/page say 360-degree chute rotation, while the manual’s standard-feature list says 270 degrees. The PTO-height inch and metric values also disagree; neither is used to promise clearance here.
BX36S 540–1000 table notation is constrained by manual p14’s explicit 540 or 1000 wording; no arbitrary intermediate speed or supplied-shaft 1000-rpm approval is inferred.
