Interesting Info...

[gamble77]

OK, so my FarmTrac rep came in yesterday and we were comparing specs on tractors, etc. and we came on the topic that FarmTrac and LG uses the Daedong motors in their 270DTC and 320DTC tractors. So, we started looking at the specs and here is what we found.

The motor that is used in the CK30 is the same displacement as the motor in the 270DTC, therefore it would make sense that Daedong only produces one motor with that displacement. But, in the CK30 Kioti claims 30hp but in the 270DTC FarmTrac and LG claim 27hp. PTO hp for the Kioti is 23, for the FT it is 23.8.

The motor that is used in the DK35 is the same displacement as the motor used in the 320DTC, so I am assuming it is the same motor. Kioti claims 35 motor hp and 28.3 PTO hp. FarmTrac and LG claim 32 motor hp and 28.5 PTO hp.

All of this seems a little strange to me but my FarmTrac rep says that Kioti must be using the highest configured gross hp available, and that LG adjust the hp a little more, therefore the lower initial hp rating but about the same PTO rating.

Just thought some of you might find this interesting...

Some years ago when I was looking to buy, I was comparing Massey with Kabota. I can't remember the displacements of each but the Kabota dealer claimed that manufacturers rate HP in different ways. His thoughts were that Massey rated HP a maximum engine RPM and that Kabota was rated at PTO operating RPM. I don't know if he was correct or not.

Kioti uses GROSS engine HP in their specs (most all Mfg. do as far as what I have noticed).
But FarmTrac uses NET HP on some of their machines.
Example- FarmTrac 360 DTC is generally shown as a 36 HP machine, but if you look closely at the spec sheet this machine has 39 Gross HP. 36 is the machines Net HP.
Most MFG.'s including Kioti would have used the 39 HP figure.

 

[gamble77]

Yes, but the FarmTrac specs for the 270 & 320 are "gross" hp...

 

[NewToy]

Isn't it possible that they may be tuned differently? Injector pump settings, etc, may account for the difference??

 

[gamble77]

The whole tunning thing may explain the initial hp difference, but the PTO hp is almost exactly the same. In fact the initially lower hp FarmTracs actually have MORE PTO hp...kind of weird.

 

[Highbeam]

Perhaps they have a more efficient drivetrain...

 

[northcreek2624]

Is it possible that they are quoting HP ratings at different RPM's? International Harvester did this with the last of the old Cub series tractors.Every year or two the HP rating went up,what many didn't notice was that so did the governor setting....Mike.

I think we can all agree that HP ratings are more "ballpark" than actual. Unless you have a dynomometer to run your own tests, I doubt you'll know for sure what the actual HP is.
Makers seem to attribute just about whatever figures they want to, and that includes all brands.
I knew someone that used to sell imports and had a dyno which showed that many of the tractors acutally spec'd out a few HP higher than the manufacturer's stated HP.
It is interesting that the same engines are coming up with different ratings, but it's probably not that acurate anyway!

I would like to see torque specs more. Not just torque at a given RPM, but a torque graph for the complete RPM range. Horsepower is a misleading number when it comes to tractors.

KO

I agree, but as you know, most of us here in the states are not all that technically inclined to understand the value of torque ratings! For most of our lives, we've judged automobiles based on HP, so tractor makers use that to their advantage in my opinion and use HP ratings instead of a more realistic torque graphing of RPM range.

[Kiohio]

I agree.
Being somewhat of a "gearhead", I would like that kind of info. LOL

 

[gamble77]

Yeah, torque charts are almost mandatory on larger tractors as farmers want to see where the power occcurs, but on smaller tractors is seems like an after thought...I too would like to see torque numbers instead of just hp numbers...and not just numbers but charts.

My Farmtrac 270DTC has an 85 CID engine. The 320DTC comes with a 100.5 CID engine. The literature I have looked at lists the CK30 as having 91.5 CID Takes a little better than 3 cubic inches to make 1 horse with all three engines.
