3-Point Hitch Kubota B20 - What size (Flail) Mower and Blade Box?

mzwillinger · Apr 20, 2018

Hi! Just got a 1995 B20 and want to get mower and blade box. Relative newbe, this is my first tractor w/PTO. PTO is rated at 13.5HP and I am wondering what this tractor can comfortably handle. I really want a 48" flail mower (says needs 20HP) and 5' blade box but not sure the tractor can handle. Step down would be 41" flail mower 16/18HP and 4' blade box. I'm assuming the these would be ok. Any thoughts or advice??
Thanks!!
-Marc.

Yes, the B20 should handle the 41" mower and 4' box blade without much trouble. While it may work with the bigger implements in some situations, they will be very taxing on the tractor.

You think the 48" flail mower would be too much? That's my tread width and be good size but I'm afraid might be too much for the PTO...

I run a Woodmaxx 62" on my BX2200. It lifts, turns and it works fine.

I got a larger one only because I am upsizing soon. A well maintained flail will use the same energy as a finish mower.

Either a 41" or the 48" will work. The 41" will seem more powerful because you are concentrating the power.

Depends on what you are doing. Most use flails for high grass and thickets. I use mine for mowing my lawn (regular grass, no debris, and normal height).

Since you didn't say what you are mowing, maybe a flail might not be a practical tool.

I'll be mowing grass and bushes, want to clear out some big black berry bushes

One thing be sure on is the lift on your tractor the size the implement is. That would be the same pin diameter for the lift pins and also the same width spacing on the lift arms as the implement. But you probably already knew that.

Ok, so I am about to make a final decision on a flail mower! I have been researching, calling around etc. The Betstco /Farmers-Helper is the best priced, imported from China assembled and sold out of Oregon. Haven't heard anything bad about them.

My Kubota B20 has 20HP engine, 13.5HP PTO and is 48" wide. Been trying to decide between a 41" (16HP required) and 48" (20HP required).

The specifications state that, for the HP requirement ,"If your tractor has gear transmission this is PTO horsepower. If your tractor has hydro transmission this is engine horsepower"

Based on this, it sounds like I am within spec for the 48". I realize I am at the limit and will need to go slow for high brush but am thinking this is my best option.

I plan to order it next week, and will be monitoring this thread until then. Ultimately I will post my results once I receive install and use it.
