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

[mzwillinger]

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!!

I have a B20.
At the risk of a "nevermind" as in a Chevy Chase - Jane Curtin SNL news/opinion skit, if you mean a 4' box blade, I have a 4' and I think a 5' would be fine ... and more useful since a 4' is narrower than your tire stance.
If you can judge flail power requirements by comparison to a finish mower, mine handles its 5' finish mower just fine. Ditto a 5' rototiller (on dead sod).

Can you tell me what the hp requirements are on your rototiller and more? Do you feel they are running strong or under powered?

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.
