Victory 2023 Flail Mower Buyer’s Guide

FMHDH-70 Heavy Duty Flail Mower with 18″ Hydraulic Side Shift

Our heavy-duty flail mower is designed to provide professional cutting of virtually any vegetation such as grass, heavy undergrowth, and tree prunings. This Mower is equipped with high-quality forged steel 800-gram flails attached to an extra thick flail shaft (6 5/8″ diameter) providing greater stability and strength. 

The FMHD-H connects to your tractor’s CAT I/II 3-point hitch. Your tractor should have a PTO performance of 40 – 75 HP. The PTO shaft speed needs to be 540 RPM. The maximum Side Shift is 18″.

NOTE: Requires rear hydraulic remotes on your tractor (Hose ends that connect to the tractor are fitted with 1/2-14 NPTF quick connect fittings).

Materials and workmanship are of the highest quality. Therefore, your purchase includes a 2-year warranty and shipping is free to your location and delivered from a liftgate truck (lower 48 States).


Our models feature rugged construction, an extra heavy-duty gearbox (50HP), high quality steel (Q345B) flail shaft, and a hinged rear gate. The extra thick rotor shaft with staggered flails achieves a superior cutting result. The electronically balanced shaft reduces vibration, provides for smooth running, and reduces the wear on the bearings.

The hinged rear gate allows for easier cleaning, flail replacement, and general maintenance. The closed gate provides for additional mulching and the open gate allows for easier disposal of the mowed material.

While the tractor’s PTO speed should be 540 RPM, the mower turns at 2,125 RPM.  The mower can be offset from the center depending on the mounting of the 3-point hitch.

When using the hydraulic side shift you can extend up to 42″ for the 64-model, 46″ for the 70-model, 50″ for the 78-model, and 54″ for the 86-model measured from the center of your tractor. This feature helps mow around fences, buildings, walkways, and other hindrances. The maximum offset can reach 18″. We include CAT I/II special pins to allow you to choose.


The gearbox allows the mower to turn independently once the PTO (tractor) stops moving.  The front of the mower has a protection guard to prevent material from being thrown out.  The heavy-duty construction of the mower’s box is designed for maximum protection.


Partially assembled machines do not contain any fuel, oil or other fluids or grease needed for operation! BEFORE USING THE MACHINE please carefully read the user manual.

2 reviews for Victory FMHDH-70 Heavy Duty Flail Mower with Side Shift

  1. Mark

    The mower arrived in great shape overall and quite quickly after I placed my order seeing as how I live in Vermont. The set up was minimal and the manual adequate to get me up and running. I needed to make a few modifications (mainly shortening the PTO shaft), but nothing that seemed unreasonable – especially for the price.

    I agree that it appears to be built quite rugged and seems like a solid, well-designed machine (admittedly this is my first flail mower).

    I’ve got about 10 hours on it so far and I’m really pleased. It’s definitely what I was hoping for. And you just can’t beat it for the price.

    So far so good. This thing is built really well
