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.
79.5″
74″
804 LBS. (mower weight only) PTO shaft weighs an additional 39 lbs. Shipping weight 1000lbs.
30-65 PTO horse power
3/4″ – 3-3/4″ Adjustable to meet various height requirements
4 Gauge .25″ structural Q235 roll formed steel for durability.

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.

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.
2nd Woodmaxx flail mower, 1st was a FM62H with hammers. Decided to see if my 35hp Kubota would run the FM78H with flails for open fields, it works great and the tractor handles it fine.
I am very impressed with this flail mower. ( WoodMaxx FM-78H ) I purchased both hammer and grass blades. I haven’t tried the grass blades yet but I’m not sure I will need them. I mowed several acres now and a lot of it was heavy thick and tall green grass with the hammer blades and the design of these hammers is superior to my other mower. They do not plug up with grass and dirt because of the vertical edge down the center of the hammers. What a great design !! The hammers are also much stronger than the cast iron blades of my old mower as well. I removed some ledge and the blades just have a few nicks in them. My old cast iron blades would have broken in half. It had happened many times. The distribution of the mulch is also superior. I love the hydraulic slide feature as well. I was worried about bending the slides but so far they have held up well, I am just careful not to hook any trees or rocks etc etc. I drive this mower with a 60hp tractor and in the real heavy thick stuff I use all 60 hp, just an FYI. Maybe that would be less of a requirement if the grass blades were installed. I will be trying them at some point this Fall.
I highly recommend this mower, long term durability is yet to be seen, I have about 60 acres now of mowing jobs and I’m excited to put it through the paces. My ground speed is increased without sacrificing cut quality so I’m hoping to be more profitable as well, and at the end of the day that’s what matters to business owners.
I bought a WoodMaxx SS-72 Snow Blower two winters ago and I’ve been very pleased with it. So when it came time to purchase a mower for maintaining our field WoodMaxx was the first place I looked. I bought the FM-78H and I’ve used it twice now to mow our 5 acre field, the first time when the grasses were overgrown to nearly 3ft high. I couldn’t be happier with this unit’s performance. Mowing 3ft tall grass you could hear the PTO lag a bit, but that’s my mistake as I should have mowed higher the first go around. I’m still playing with adjusting the mow height.
I am very impressed with the build quality of this unit. I looked at a lot of different mowers, but this unit is solid AND at a great price. I’d recommend it to anyone that has a field to maintain.
Great Mower! I have the FM-78H on my 2021 Kioti CK4010se with a cab. The side shift is awesome. I have 33 pto hp and this mower works great with the hammer blades. This is my first flail mower and I’m impressed
