THE BUYING PERSPECTIVE
Know before you order.
- Y-blade configuration only: current manual p40 lists 15–25 PTO hp. The hammer configuration requires 20–25 PTO hp; never apply the 15 hp minimum to hammers.
- The FM-54 name does not mean a 54-inch cut. Current page and manual both give 47 inches; overall width on the page is 56 inches.
- Manual specifies 18 Y-blade sets; page says 36 individual Y-blades. The hammer alternative has 18 individual hammers.
- Page states Y-blade and hammer-equipped mowers are not interchangeable. Order the required configuration rather than assuming a later blade swap.
- Manual gives 3/4–3-1/2-inch cutting height; page says 3/4–2-1/2 inches. Confirm usable height for the delivered revision.
- Use 540 rpm PTO input; 2,092 rpm is rotor speed.
- Current product weight and page mower-only-plus-shaft figures differ. Confirm the complete Y-blade assembly before any lift comparison.
- The November 7 price observation is for the black Y-blade SKU FM-54-0010. The general FM-54 photo does not independently verify the supplied rotor configuration.
