NSK BRAND SHAFT BEARINGS

NSK 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.

OVERALL WIDTH

56"

CUTTING WIDTH

50"

WEIGHT

410 lbs. (mower weight only) PTO shaft weighs an additional 39 lbs.

HP REQUIREMENTS

18-40 PTO horse power

CUTTING HEIGHT

3/4" - 4" Adjustable to meet various height requirements

DECK PLATE MATERIAL THICKNESS

3/16" .1875" Structural Q235 steel for durability.

SIDE PLATE THICKNESS

3/16" .1875" Structural Q235 steel for durability.

BLADE TYPE

Hammer or reversible Y-blades. Our hammer blades are 40cr, alloy 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 1 lb. 15 oz. (cast steel is much more durable than cast iron) competitors use flat face blades. The reversible Y-blades are made from .42" 60si2mn, spring steel, (American standard: A29m) formed, heat treated, and quenched in oil. They weigh 1 lb. 7 oz. for the set. Use the hammer blades for clearing saplings (1" diameter or less), and the Y-blades for grasses.

NUMBER OF BLADES

18 Hammer or 36 Y-blades.

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

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 - 3"

3"- Heavy duty 5/16" 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 bearings.

BALANCED CAST IRON PULLEYS

The V-belt pulleys are heavy duty cast iron and balanced to eliminate vibration, and run smooth.

ROTOR SWING DIAMETER - 10.75"

Large swing so that the blades build required inertia.

ROTOR SHAFT SPEED

2092 RPM

High speed = Efficiency to cleanly cut material

Category 1 standard 3-point or category 1 quick hitch - will attach to any category 1 3-point hitch and will also work with cat 1 quick hitch. Not I-Match compatible (sorry!)

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 exc. From the center of the PTO the mower extends 31" to the right and 24" to the left.

DRIVE BELTS

3 Total B-series USA gates "truflex" - we use only USA made gates belts on our flail mowers for long life.

EASY DRIVE BELT TENSION

A single bolt on top of the mower is utilized to replace and provide tension to the belts.

PTO SPEED

540 ONLY

GEARBOX RATING

Up to 45 hp. Heavy duty proven oil bath gearbox for long life.

GEARBOX TYPE

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.

DRIVELINE / PTO SHAFT

1-3/8" 6 spline w/slip clutch.

GREASEABLE SHIELDED BEARINGS

Accessible greasable bearings for easy maintenance.

REAR HEIGHT ADJUSTING ROLLER DIAMETER

4.25" 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.

POWDER COAT FINISH

The rust resistant baked-on powder coat finish is more durable than conventional paint to keep your machine looking good for years.

WARRANTY- 2 YEARS

A robust machine with an equally robust warranty.

SERVICE

At WoodMaxx our service department is staffed with professional certified technicians that inspect each machine before it is shipped. This ensures that you get a trouble free machine from the get go. When you need technical help or parts, our courteous staff can help you get what you need from our fully stocked warehouse.
