Section 6: Features & Benefits

FM31 & FM41 Series Flail Mowers

Features

Benefits

88” Cutting width

A good cutting width for many applications.

35-80 HP Gearbox Rating

Fits a large array of consumer, municipality and landscape of tractors.

3-Point screw type hitch can be
offset 7 3/4” Left & right

Easily offset the hitch for a closer cut alongside buildings, fences, roadsides and for getting
under tree limbs.

ACME threads on offset

ACME threads are deeper allowing for easy screwing adjustment.

One year gearbox warranty

The gearbox is designed tough to withstand the rigors of flail mowing.

540 RPM cast iron gearbox with
over-running clutch

Enables the rotor to free swing to a stop when the tractor PTO has been turned off.

1/2” – 6” Cutting height

Variable cutting heights for many uses.
Lowest cutting height allows for scalping in grasses such as Bermuda prior to overseeding.

1” Cutting capacity (31 Series)
2” Cutting capacity (41 Series)

Cut saplings when used in a rough setting.
41 Series is good for chopping up tree trimmings.

Fine cutting knives (31 Series)
Forged hammer knives (41 Series)

Heavy enough to cut 1” material, yet fine enough to groom a yard.
Forged hammers are just right for chopping up prunings up to 2” thick, but will also groom
grass in a very acceptable manner.

Brush rake teeth (41 Series Only)

The adjustable brush rake teeth continually push prunings into the knife path for repeated
chopping action.

5 1/2” Rotor diameter

Large rotor is able to take rough conditions.

Reverse rotor rotation

Brings the cut material up and over which allows it to be dispersed more evenly.

High knife tip speed

Knife tip speed of 9,805 fpm for cleaner cut.

Cat. 4 driveline

Heavy-duty driveline matches up with HP range as well as potential conditions.

4 - “SPB” Section belts

“SPB” Section belts have more surface to pulley contact and fits deeper in the groove.

3/16” Deck thickness

Allows the mower to handle rough conditions.

Baffles on top inside of deck

Keeps cut material from clumping together, ensuring an even distribution of clippings.

Height adjusting roller

Rear height adjusting roller with greaseable bearings and tapered ends to prevent
gouging during turns.

Standard scrapers on rear height
adjusting roller

Keeps roller clean for consistent cutting height.

Hinged rear gate

Can be opened for easier discharge in heavy conditions, or left closed for greater
mulching capabilities.
