I also was lucky enough to find a dealer for yanmar the same distance from home just in the opposite direction of the kubota dealer and they have been great in this whole shopping and comparing process as well. I do have a few questions that i need a little help with. The kubota has 3 hydraulic pumps and the yanmar has 2 variable piston pumps. If you look at the Bh hydraulic flow rate you get 18.2 from what i can gather for the kubota vs 22 for the yanmar. It's weird that the kubota has 3 pumps vs 2 pumps but they have less flow rate to the backhoe. I guess that may just be because of the way yanmar builds their hydraulic systems which i have been told is one of their strong points along with their reputations for motors and trans building. Any other info is more than welcome as i still have some thinking to do and need all the help i can get so i don't have to do this again next year. Thanks again to all those who are able to help |
Despite rather significant differences in hydraulic system design, I wouldn't get too hung up on the pump specs. The fact is that
BOTH machines have perfectly adequate flow to the backhoe main circuit (11 GPM) and both have separate pumps and/or circuits feeding the backhoe swing function. I hedge a little on the latter statement because Yanmar has not been at all clear about the exact control logic and hydraulic piping despite repeated attempts by me to obtain that information. I have even gone so far as to call the Yanmar engineers in Japan with limited, confused and ambiguous results.
On top of that, they were said to be changing how they state their specifications for the American market... although I have yet to see any "new" specification for the CBL-40.
Regardless, beware of counting the power steering flow in or for anything. It has nothing to do with loader or backhoe operation. Kubota clearly has all gear pumps and a separate gear pump for power steering. Yanmar is silent about that point. It is not clear if the CBL-40 borrows from the two main pumps for power steering... or if there is a separate gear pump. I suspect it could be the latter... but there is nothing I've seen in writing to confirm that. My "theory" is based in large part on the set-up I see in my Yanmar VIO35-3 mini-excavator (4 pumps: 2 variable flow, 2 gear).
The bottom line is that the big
operational advantage of the CBL-40 comes from its extra weight and it's ultra-powerful FEL. The big
ownership advantage of the L39 comes from it being a Kubota with very high resale value and a magnificent dealer network.
If I were going to buy a CBL-40, I'd definitely try to find a leftover or slightly used one. Prices have historically dropped fast on used Yanmar equipment.
The reasons appear to be a generally weak dealer network as well as a hardy supply of used ex-rental equipment. Yanmar seems to be the darling of ma and pa rental places everywhere.
