NSK BRAND SHAFT BEARINGS
is a leading bearing and motion control manufacturing company founded in Tokyo,
Japan in 1916. Today NSK has several plants around the world including England,
Germany, USA and Switzerland and by far one the best quality bearings available
on the market today. Although these bearings are very costly, we feel that in
an application with high load and dynamic forces such as a flail mower that
such high quality bearings are required. These bearings are noticeably
smoother, quieter, and cooler running than any competitor and far superior to
any no-name brand. Some inferior bearings contain plastic interior ball cages
that are susceptible to breakage from shock loads. Poor material and tolerances
generate excessive heat that translates into premature bearing failure and even
belt wear as the heat travel to the pulleys and the belts. All bearings are not
created equal, and this is a feature that should not be overlooked when
shopping for a flail mower.
1243 lbs. (mower weight only) PTO shaft weighs an additional 39 lbs.
3/4" - 4" Adjustable to meet various height requirements
DECK PLATE MATERIAL THICKNESS
1/4" structural Q235 roll formed steel for
SIDE PLATE THICKNESS
3/8" Structural Q235 roll formed steel for durability.
Optional duck-foot or reversible double Y-
blades. WoodMaxx duck foot blades are made from
structural steel. (American standard, AISI/SAE/ASTM steel no: 5140) and
forged to a tapered wedge shape to avoid material buildup
on the blades.
Each blade weighs 2.5 lbs. (cast steel is much more
durable than cast iron) competitors use flat face blades.
The reversible double Y-blades are made from .24" 60si2mn, spring steel, (American standard: A29m) formed, heat treated, and quenched in oil and weigh 2 lbs. each. Use
the duck-foot blades for clearing saplings (1" diameter or less), and the Y blades for grasses.
NUMBER OF BLADES
16 Duck foot blades or 16 double Y blades (32 Y-blades total)
PRECISION BLADE OVERLAP
The blades are staggered
precisely with no gap in the mowing area. Blade overlap is important to achieve
an even cutting result.
ROTOR ROTATION- REVERSE
The rotor spins in the opposite
direction as the wheels of the tractor when traveling forward. This allows the
blades to shear the material as it is folded forward by the mowers. The
material is then thrown up and over the rotor.
ROTOR TUBE DIAMETER - 5"
5"- Heavy duty 3/8" wall tubing for long life.
BALANCED ROTOR TUBE
The rotor tube is balanced to reduce
vibration and ensures that the mower runs smooth, and reduces wear on the
BALANCED CAST IRON PULLEYS
The V-belt pulleys are heavy
duty cast iron and balance to eliminate vibration, and run smooth.
ROTOR SWING DIAMETER - 15"
Large swing so that the blades build required inertia.
ROTOR SHAFT SPEED
BLADE SPEED - 138 FT. /SEC.
High speed = efficiency to
cleanly cut material
Category 2 only.
OFFSET FROM PTO CENTER
This feature allows for offset
from center to the right of the tractor. This feature is helpful for mowing
around fences, buildings; walkways etc. From the center of the PTO the mower
extends 57" to the right and 31" to the left.
Four Total B-Series USA gates "truflex" - we use only USA made gates belts on our flail mowers for long life. (easy to find SAE standard size BX49)
DRIVE BELT TENSIONER
Solid state automatic - this
feature automatically adjust the belt tension so you don't have to worry about
slippage or overworking the belts. This feature greatly increases the belt
Up to 90 hp. Heavy duty proven oil bath gearbox for long life.
Cast iron 540 RPM with internal
over-running clutch - when the PTO shaft is disengaged the built in over
running clutch allows the PTO shaft to stop turning while the gearbox and rotor
shaft slow down gradually. This is an important feature, without it, the
gearbox will slam to a halt when the PTO is disengaged, causing stress to the
gearbox and your tractor. This feature should not be overlooked when shopping
for a mower.
REPLACEABLE SKID SHOES
The skid shoes reduce gouging
are bolt on so you can adjust or replace them easily when the time comes.
The FM-88 is equipped with removable rakes. The purpose of these rakes is to keep the cut material inside the mower housing until it reduces enough to pass through the rakes. This provides for smaller discharged material. Additionally, the rakes can be adjusted up or down so that the tip of the rakes slightly "rake" material from the ground further mulching it. For quick mowing of heavy vegetation simply remove the rakes completely.
DRIVE-LINE / PTO SHAFT
1-3/8" 6 spline w/slip clutch.
GREASEABLE SHIELDED BEARINGS
Accessible greasable bearings
for easy maintenance.
REAR HEIGHT ADJUSTING ROLLER DIAMETER
5.25" With tapered ends - this
roller contacts the ground to ensure even cutting height. The ends of this
roller are rounded to eliminate gouging when turning corners. A scraper bar
ensures that mud and debris buildup is cleaned off as you go.
The rust resistant baked on
powder coat finish is more durable than conventional paint to keep your machine
looking good for years.
