bx power

[TMGT]

Powers not necessarily for pulling power, there are some static pto powered implements that benefit from more pto power, chippers is the first to come to mind.

You also have to look at engine size and where it makes the power. The bx2670 uses the 1.0L, the b2601 uses the 1.1L at a lower rpm, the b2650 uses the 1.3L at an even lower rpm. Same HP at lower rpm = more TQ.

FEL and BH's don't require a lot of hp to run.

Good points. Especially on compatible chipper sizing.

Wow, First time I have seen torque mentioned. I think I need to go investigate the different torque ratings for the BX25 versus the B2650. I had just assumed that I wood chipper would be too big for either of these tractors.

 

[TMGT]

I believe the bx25 uses the d905, the b2650 uses the d1305, kubota should have the hp/TQ curves listed online somewhere

 

[TMGT]

Quick calculations, the bx25 has 37.7 ft lbs at rated rpm, b2650 has 54.6ft lbs, this doesn't take into account where the peak is or the area under the curve which can make a big difference.

Well, that is 45% more torque for the B2650. That would go along way to make a wood chipper more responsive to bigger diameter pieces, because the torque would help prevent the RPMs from slowing way down. I was thinking of getting a smaller wood chipper for my BX25, but I felt that the 17 hp PTO rating was a bit on the light side.

I run a Jinma chipper on my b2620, have been very impressed with how well it runs it, can always use more power though!
I'm getting ready to add a turbo to mine.

You can put a tirbo on these things??!! How much power does it add?

This is where I'm at too and decided against a chipper, although mainly due to cost. Really liked the Walllenstein BX32 until I found out the price.

You can put a turbo on just about anything lol, but luckily kubota offered a factory turbo on the d1105 engine in certain applications. I have access to a parts engine for most of the little parts and have a low hr turbo and manifold.

Biggest issue will be fitting it in the engine compartment.

Should be about a 4-5hp increase, however it will also be more responsive and torque curve will be fatter. I don't live at a high elevation so that doesn't matter as much.

Im not saying the 23hp needs more power but I wonder why the 2670 has the bigger engine. Dosent have a backhoe. I would just think the 25 would need the extra power for the hoe..

I surely doubt that the hydraulic pump is taxing the engine to run the hoe even with larger flow I don't think it would matter to the engine. 23 HP would drive a large hydraulic pump without overloading the engine. I don't even hear the RPM change at all on my B26 when using the hoe or FEL so I don't think it is using a lot of power to run it.
As others have said, why do you need more power if you can spin all 4 wheels. My B26 weighs almost 3 times as much as the BX and gets along fine with 26 HP engine

 

[davesl708]

My BX2200 runs the FEL, 60" MMM and a 60" tiller as well as pushing snow and moving large rocks. The engine has never loaded down or even acted like it was under heavy load. All four wheels will spin when pushing into dirt or large rocks.

More lifting capacity on the FEL would be nice on occasion but not worth getting a larger tractor.

Your bx would pull a smaller chipper. I run a wallenstien bx42 (rated 4") with my B2920 all the time. 3" dia pieces gets chewed up easily. Anything bigger than 3" is firewood anyhow. 4" "hard" wood is too much for it. I'll put the chipper on the m7040 and let her rip.

For those that want more lifting out of the FEL check your hydraulic pressure. You can shim the relief valve to raise the pressure. I shimmed my BX22 to 2000lbs and what a difference it made. The only problem I've had was the 16 year old weathered hydraulic hoses. When one springs a leak I just replace both hoses on that cylinder. I have the hoses made at half of the cost of a Kubota hose.

I have a shim kit... just haven't gotten around to it yet.
