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.

Duckfoot or reversible Y-blades. Our duckfoot 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 1.85 lb. (cast steel is much more durable than cast iron) competitors use flat face blades. Side by side comparison of WoodMaxx exclusive duckfoot design: The reversible Y-blades are made from .33″ 60si2mn, spring steel, (American standard: A29m) formed, heat treated, and quenched in oil and weigh 1.75 lb. each. Use the duckfoot blades for clearing saplings (1″ diameter or less), and the Y-blades for grasses.
22 Duck-foot or 44 Y- blades w/ 22 ctr blades between the Y (WoodMaxx exclusive)
The blades are staggered precisely with no gap in the mowing area. Blade overlap is important to achieve an even cutting result.
This allows for easy inspection, cleaning, blade changing, and maintenance of your machine. The rear gate can also be left open for easier discharge in heavy conditions, or you can close the gate to greater mulching.
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.
4.25″- Heavy duty 5/16″ wall tubing for long life.
The rotor tube is balance to reduce vibration and ensures that the mower runs smooth, and reduces wear on the bearings.
The V-belt pulleys are heavy duty cast iron and balance to eliminate vibration, and run smooth.
Large swing so that the blades build required inertia.
2160 RPM
128 ft./sec – High tip speed = efficiency to cleanly cut material
Category 1 standard 3 point or category 1 quick hitch – will attach to any cat 1- 3 point hitch and will also work with cat 1 quick hitch (except John Deere I-Match)
Shifted left (36″L/43″R), shifted right (22.5″L/57″R). This feature allows for variable offset from the center to the right of the tractor. This feature is helpful for mowing around fences, buildings, walkways, etc. Total offset can reach 18″. NOTE: Requires rear hydraulic remotes on tractor. We cannot supply these if your tractor does not already have them, they must be dealer or factory installed. (Hose ends that connect to the tractor are fitted with 1/2-14 NPTF threads, you will have to provide the corresponding fittings to complete the connection to your tractor.)
3 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 belt size BX39)
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 life.
540 ONLY
Up to 55 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.
The skid shoes reduce gouging are bolt on so you can adjust or replace them easily when the time comes.
1-3/8″ 6 spline w/slip clutch.
Accessible greasable bearings for easy maintenance.
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.
A robust machine with an equally robust warranty.
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.

So far so good. It does mow well and unfortunately I needed to mow my hayfields as they were too wet this season to hay. It did a great job with a 55hp New Holland tractor mowing a full years worth of grass in my hayfields. The workmanship was just okay. You have to double check the tightness of every nut and bolt as I found many loose. When I went to adjust the mower skids, I had to retap every nut as they would not thread back on otherwise. It took my Milwaukee 1/2″ high torque to get them apart. The bolts were fine but the nuts had threads that were really poorly cut. It might have been an engineered thing gone wrong in an attempt to keep them from backing off but you have to be able to thread the nuts back on the bolts. I’ll replace the nuts now with Nylocks as the original setup was without lock washers. They are made in China so you get a good price but… The design is fine and it should be great for what I need moving forward.
First time flail mower owner, wanted something to mulch up the grass in my field after I was done taking hay for the season. Put it behind a mostly worn out Long 445 and it did fine. I set the skid shoes at the tallest cut height and it struggled to cut the tire tracks, I plan on lowering it a bit next year to try and solve that. Build quality seems good, it’s a very heavy unit. I would prefer a shear bolt option over the slip clutch but so far it’s been fine and even heavy johnson grass doesn’t slow it down much. Y-blades do well and have held a decent edge after 20 acres of cutting.
I had my FM78H with Y-Blades delivered about a month ago and have mowed about 10 acres with it so far. The delivery was pretty much painless. I had it shipped with a liftgate truck and they dropped it right in my yard. It took me a couple of hours to remove from packaging and assemble but it was fairly easy and straight forward. I have a 1985 Case IH 485 (approx 43 PTO hp). The mower is definitely heavy but I see smaller tractors reporting positive results. After sizing the PTO shaft it was easy to start using right away. I had a bit of a problem hooking up the hydraulic connections for the side shift but this was a problem with my tractor, not the mower. Still, I was able to use the mower to great effect (without side shift so far) and the tractor had no problem pulling it through some dense grass and weeds. It handles 1 inch saplings with ease. I started with the lift gate down but it definitely helps to run it with the gate open in denser material. In this configuration, I can comfortably operate in 2nd gear without straining the mower or tractor. All of the nuts and bolts appear to be tight and keeping their tightness. I think the Y-Blades were the right configuration for me as they are quite heavy themselves and cut very well. I adjusted the cutting height one notch before using. This is a bit of work but quite easy and straight forward. Very pleased so far.
Purchased the FM78 a couple months ago. First job I did was some light brush with the hammer blades. Does a great job on blackberry bushes! Last night I changed the blades out for the Y blades. Mowed 10 acres today non-stop and it did a fantastic job. Mostly grass between 1 and 3 feet tall. Does a fantastic job mulching. I wasn’t super concerned with that and just needed to get the field mowed so I opened the gate for faster ejection and was able to move up another gear. Even with the gate open it still did an awesome job mulching. The side-shift is great for fence lines and getting close to buildings. I am using a 1983 John Deere 2150 with 45HP output. This is a great machine. Super tough runs like a champ! 5 stars!!!
First time owning a flail mower, very impressed with its performance of the duck foot blades. I would recommend it to anyone. Running on a 35 horse Kioti.
