Dittos. I went with the B2650 as well to avoid any potential issues with the DPF. Also, the b2650 has the same engine as the b2920 so I've been assuming that it's capable of 29 hp if its tuned correctly. I haven't had been he been rage or need though to explore that. I've had plenty of power so far.
I'm not trying to beat a dead horse or bring up old topics for no good reason, but anyway...
I'm starting my hunt for a new tractor. Wanted a 2920 years ago because of the hp without the emissions. Long story short the 2920 and B2650 use the same motor (D1305), that puts out the exact same power.
As it turns out, the difference lies in the factory ratings:
The B2920 is factory rated at 29hp at 2800rpm's
The B2650 is factory rated at 26hp at 2500rpm's
What does this mean? Well horsepower is a function of torque at a certain rpm. If you break down the numbers, the B2920 creates a of 54.4 ft lbs at 2800 while based on the same exact calculation the B2650 produces 54.62 ft lbs at 2500 rpm's.
As the old saying goes... horsepower sells cars, torque wins races, it kinda applies here as well.
So back to those numbers...
B2920 rated at 29hp at 2800rpm's = 54.4 ft lbs tq
B2650 rated at 26hp at 2500rpm's = 54.62 ft lbs tq
Now to throw another tractor in the lineup I'll use the B2601, which has no bigger brother unlike the B2620 did when the B2920 was an option
The B2601 is factory rated at 26hp at 2800rpm's = 48.77
So the 26 hp b2650 is technically more powerful than the 26 hp b2601 because it produces more foot pounds of torque, which torque is the measurement of the actual work an engine can do.
Once again sorry about bringing up an old post, but I've just been hoping all along that Kubota would offer an equivalent tractor in time to the B2920 with the upgrades of the current 01 lineup (b2901). Turns out they do and its been hiding under our noses all along as the B2650 and it has not been plagued with the DEF issues the B3350 has been going through.
