29 pto hp from a BX

[Sidekick]

Just watched a video about a company developing a BX turbo. Should be for sale soon.

Sorry I couldnt watch this longer than about 3 minuets, this guys voice just grates on my last nerve

So.... does he upgrade the rest of the drivetrain ????

LOL

Not until it explodes .
I see people putting turbos on l2501s without a problem and that's a lighter drive train then the 35s and 40s.

He does take his time getting to the primary subject. He's apparently one of those folks who you ask what time is it, and he tells how to build a watch!

If you need more horse power in a BX then it is time to upgrade to a larger tractor.

I couldn't really understand him ( sub titles would have been nice...)
so numbers... new HP/OLD HP * engine HP = new engine HP...

29/17.7 x 23 = 37 Engine HP ??

Ain't no way a BX23 is going to pull my 3F plow, 5' rear blade, let alone the single shank subsoiler or the 5' rototiller
so I'm curious..
really WHAT is the point ?

You have to watch him on 2x speed.

I watched with CC on sound off.

Poor lil' transaxle...

Poor lil' transaxle...

It wouldn't raise the transaxle pressure on the machine at the same rpm so I wouldn't worry. The pto shaft may be in trouble though.

 

[GreensvilleJay]

so, nuther question...
WHAT implement needs 29HP that can FIT onto a BX23xx ??

When I owned a BX25 I could have used more hp, a lot more hp! I'm only at 3,200 ft elevation but my property is hilly so hp matters. The mid PTO ran the 50" snow blower and 54" mid mount mower just fine, but overall I found the little BX25 to be lacking in many areas.

I’m probably going to out myself as being ignorant with this question but if so, it wouldn’t be the first time.

I understand increasing engine HP increases PTO HP and increases HP to the wheels on a gear drive. That’s not the question.

On a HST the engine is a driving a hydraulic pump that feeds a hydraulic motor that drives a series of gears and shafts that turn the wheels. So on a HST increasing engine HP doesn’t seem like it would result in a commensurate increase in HP to the wheels unless you also changed the hydraulic pump and/or hydraulic motor.

So, for example, you turbo a naturally aspirated engine on an HST tractor and increase HP not just a small amount, but say 25 PTO HP to 40 PTO HP. You can get access that full 40 HP on the PTO (assuming it doesn’t twist some part of the driveline in two) but how much, if any, of that extra 15 HP are you going to actually get to the wheels if you’re running the stock hydrostatic transmission (variable displacement hydraulic motor) which is being fed by the stock hydraulic pump?

Correct. You basically just run the new power up to the factory HST relief limits. On the L2501, for example, those relief limits can’t be met at the factory HP level. The tractor stalls before it gets there. But, with the Turbo, you can reach them easily in Medium and High gear. Luckily, it’s a nice improvement and can be easily felt and appreciated.

The L2501’s factory HST limits are just a hair lower than the L3901. So, essentially, the Turbo L2501 HST making 45HP is able to put roughly 38HP to work.

PTO HP is PTO HP and the improvement the Turbo provides is amazing.

Thanks for a thoughtful and informative response.

That makes a lot of sense. So for the 2501 you can get most of the HP increase through the HST. However, it sounds like how much of any HP increase on a HST machine can be applied all the way to the dirt could vary quite a bit depending on the specifics of the model involved.
