FM-62H · Hammer blades

THE BUYING PERSPECTIVE

Know before you order.

• Current manual distinguishes 24–45 PTO hp for hammers from 20–45 PTO hp for Y-blades. The page’s generic 20–45 PTO hp claim must not be applied to this hammer configuration.
• This record covers hammer blades only. The product page says hammer and Y-blade configurations are not interchangeable; choose the configuration when ordering.
• Use 540 rpm at the tractor PTO. The 2,160 rpm figure is rotor speed, not tractor PTO speed.
• The manual includes fittings, but says different fittings may be needed for a particular tractor. A hose thread size does not establish tractor quick-coupler compatibility or hydraulic pressure.
• The current manual labels its weight as product weight without identifying shaft, oil or packaging inclusion. Resolve the page/manual discrepancy before comparing a tractor lift rating.
• No tractor pairing, slope capability, throughput or physical performance has been verified.
• The current manual and detailed page specification say Category 1 only. A page introduction also mentions Category 2; do not approve Cat 2 use from that introduction.
• The model name does not describe the cut: actual cutting width is 55 inches. Page overall width is 65 inches; manual product-dimension labels differ, so confirm transport/storage dimensions.

Unit weight

860 lb — Current 2025-and-newer manual, printed p40 / PDF p41: 860 lb product weight; shaft/oil/packaging inclusion is unstated. Page instead lists 716 lb mower-only plus a 39 lb shaft. Shipping is separately labeled 860 lb. Do not treat the manual number as verified complete operating weight; confirm delivered hammer assembly.

Hydraulics

Tractor rear remotes are required for hydraulic side shift. The manual documents two hoses and supplied fittings, with 1/2–14 NPTF hose ends. Flow, operating pressure and required valve/circuit type are not stated; confirm them and tractor coupler compatibility before purchase.

Accessories & setup

Page includes a 1-3/8-inch, six-spline PTO shaft with slip clutch, gearbox oil and hydraulic quick-connect fittings. The manual requires tractor-specific shaft sizing and notes fittings may need replacement for the tractor. Quick-hitch/bushing items are offered separately.

Specifications are manufacturer-published, not measured by Acreage Equipment. A shipping weight is not treated as operating weight.
