WoodMaxx MX-9900 vs Farmer-Helper FH-BX62S: two 25-PTO-hp chippers, $4,598 apart

MX-9900 and FH-BX62S both start at 25 PTO hp, so a tractor in the high 20s clears both by the same margin. They differ in almost everything else: MX-9900 has an operator-controlled hydrostatic feed with reverse and a 9-inch opening; FH-BX62S relies on gravity and the rotor to pull material in, carries a 45-hp ceiling and has unreconciled weight and capacity figures.

START WITH THE DECISION

Consider MX-9900 for controlled feeding and larger softwoodShortlist MX-9900 when an adjustable, reversible feed matters on a tractor near 25–30 PTO hp, when bulkier softwood needs the larger opening, and when the budget allows.

Consider FH-BX62S for a lower price inside 25–45 PTO hpShortlist FH-BX62S when the tractor is clearly within 25–45 PTO hp, gravity feeding suits the material and price matters most.

The differences that matter.

Same minimum, different ceilings

MX-9900’s manual lists 25 PTO hp as the minimum and states no maximum. FH-BX62S’s current manual lists 25 PTO hp minimum and 45 maximum.

A tractor between 25 and 45 PTO hp is inside both. Above 45, FH-BX62S is outside its range; MX-9900’s missing maximum is not approval for unlimited power, so ask WoodMaxx before pairing it with a much larger tractor.

Hydrostatic feed with reverse versus gravity feed

MX-9900 uses a self-contained hydrostatic feed whose speed and direction the operator sets with a control bar, using 10W-40 motor oil in its own circuit. FH-BX62S is the gravity, pinch-and-pull S model with direct PTO drive and no verified powered feed or reverse.

Near the 25-hp minimum, a feed the operator can slow or reverse helps keep the rotor in its working range. FH-BX62S has fewer feed parts to service but depends on the rotor pulling material in.

Capacity statements at the minimum

WoodMaxx describes 5-inch hardwood or 7-inch softwood at 25 PTO hp and associates full 9-inch capacity with 50+ HP. Betstco’s current manual lists a 6.5 × 12-inch feed capacity; its listing and older manual market a 7-inch diameter, and its documents name 45, 50+ or 75 HP for full capacity in different places.

MX-9900 publishes a usable statement at the minimum; FH-BX62S does not reconcile its claims. On a 26–30-hp tractor, ask Betstco for a diameter at your rating before comparing openings.

Weights that need confirmation on both

MX-9900’s manual lists approximately 816 lb dry, and its page lists 1,048 lb shipping. FH-BX62S figures range from 797 to 835 lb net and 850 to 915 lb gross or shipping across its page and two manuals.

Both are around 800 lb, within the 1,720-lb rating at 24 inches of compact tractors such as the Mahindra 1600 Series, but neither has a confirmed complete operating weight. Ask both sellers for the assembled weight with shaft and oil.

$4,598 apart on the dated observations

MX-9900 was observed at $6,990 and FH-BX62S at $2,392, both on November 7, 2026.

The difference pays for a powered, reversible feed and a larger opening. If gravity feeding suits the material and the tractor is clearly inside 25–45 PTO hp, FH-BX62S costs about a third as much.

A CONDITIONAL SHORTLIST

Which direction makes sense?

Consider MX-9900 for controlled feeding and larger softwood

Shortlist MX-9900 when an adjustable, reversible feed matters on a tractor near 25–30 PTO hp, when bulkier softwood needs the larger opening, and when the budget allows. Ask WoodMaxx what it expects at your exact rating.

Consider FH-BX62S for a lower price inside 25–45 PTO hp

Shortlist FH-BX62S when the tractor is clearly within 25–45 PTO hp, gravity feeding suits the material and price matters most. Resolve the manual revision, capacity claim and operating weight with Betstco before ordering.

Keep these source limits with the decision.

FH-BX62S capacity and power statements conflict: 45, 50+ and 75 HP appear as full-capacity figures in different documents, and the 7-inch marketing diameter differs from the 6.5 × 12-inch manual feed capacity. Weights range from 797 to 915 lb across four figures.

MX-9900’s page says factory oil is filled while a lower paragraph instructs an initial two-quart fill; page gas-spring downforce (175 lb) differs from the manual (120 lb).

This comparison reuses the manufacturer evidence retained in the product records reviewed November 7, 2026; product pages were not re-fetched on November 8. MX-9900 uses the current product page and the Rev C manual; FH-BX62S uses the current index-linked FH-BX42 & 62 manual and records conflicts with the older Revision 1-3-2018 manual.
