First, welcome to the TBYNET forum... you will learn so much from all the knowledgable people here...
Oh, if it were only so simple on matching horespower to implement size ... because the size of the tractor also comes into play....
Your question dealt with not only the HP specification, but also type and size of implement. Two different issues to contend with...
First on the horsepower issue... Certainly the amount of horsepower the engine is rated at is a guideline... Generally, the engine is rated at the "peak" horsepower and RPM.... sometimes this is measured at the "Flywheel" like a lawnmower or garden tractor mower.. You know, says a 22HP Briggs and Stratton motor... ya but at the crankshaft, you may be getting a 1-2 HP....or in the case of net HP, generally, that is which is available to the rear wheels... that amount of horsepower varies across the RPM spectrum on all engines, gas or diesel.. The PTO HP is ofcourse another important measure and is controlled by the HP output of th engine and is that which is measured obviously at the PTO output to drive the implement...
You see the significant drop, 8 HP difference on the
B2910 since power is always taken by the transmission to drive the tractor.. an HST transmission takes more power... a gear drive generally has a 3-4 HP loss to the PTO... just like an automatic versus stick shift in car due to the direct gear drive.
But the ability of which size implement, ie 4ft vs. 5ft vs. 6 ft depends on the type of implement first... If it is a PTO driven implement... PTO HP should be used as the first litmus test... ie tiller, mower etc.. however if it is a plow or blade and does not use the PTO, then the engine HP is more the determining factor..
However, all this being said, there are other important factors, such as tire style, R1 vs. R4 vs. R3....and "weight" of the tractor in combination with the tire style.
The
B2910 weighs only 1760 pds...this is fairly light in even in the compact tractor world....if you were to have Turf tires on this and attempt to pull a plow you would not be able to transfer the engine power to the ground and thus the implement. If you were using a finish mower, on grass, totally different story.... If you have R1 (ag tires) you will have better traction performance to pull the plow, but again weight is an issue... Many other tractors in the 30 - 35 HP range weigh 2500 - 3000 pds or more, transferring the engine power to the ground.... Blending the correct tire and power to the tasks at hand...
Again, depends on what you want to do on the farm... if money is no object.. you can always go overkill... heavy machine, lots of power....
The
B2910 I think would generally be viewed by most as a high quality somewhat light ag, gardening or landscaping machine.... you would want to move up to a heavier Kubota machine for farming chores or heavy snow situation etc.....or, look at heavier tractors in that same horsepower range like Kioti, Mahindra, Century/Branson, etc. etc...
So I really haven't specifically answered your question, but I can tell you that my 25 HP, 21 PTO rated, 2400 lb. tractor handles a 5ft blade and 5ft finishmower just fine....and drives a 48 inch tiller... but would probably not do very well with a 6ft implement of any kind due to the weight and power.....
