new horsepower vs. old horsepower

I know this is comparing apples to oranges - I've been helping BIL fill silo the past week and we had the new Deere 6430 hooked to the blower. We had been using a 4030 for the same chore. 6430 is 103hp and the 4030 is 80ish. 4 cylinder vs. 6 cylinder, turbo vs. non turbo.

I can definitely put more silage up the pipe with the new tractor. It seems like the old tractor had torque while the turbo does the work on the new one. Sometimes I think the computer can't decide what to do with such a variable load.

Has anyone else been sitting on the seat trying to figure out if there is a difference? At a bare minimum the new tractor is so much quieter I would rather stand beside it with out my brain rattling. And yes, I'm wearing earplugs.
 
Hmm, if the new tractor has 25 percent more power, why is it surprising it will do more work? If you'd said the 4030 could pull the same load as the 6430. now that would be surprising.
 
I have a MF1105 that is 105HP with a turbo and a MF5465 that is 100HP with turbo and the newer engine just seems like it will outwork the older all day. I say it "seems" like it will outwork it because of how smooth it is, they would probably do about the same work.

The computer control on the newer engine just really keep them working exactly where they should be, that new tractor will really put the power out without making the operator feel as if he is taxing the machine.

That along with the quiet really makes me smile at the end of a day of work, I get out of the cab and my head isn't throbbing (and yes I wore ear plugs in my JD2950, traded in for new MF) and I'm still clean and the engine hasn't gotten hot and seems ready to work all night.

Basically these new machines are well engineered and will really work, but yes I also worry about the repairs once they get 15 to 20 years old, time will tell.

Just my thoughts......
 
We used to use 40 and 50HP 3phase motors to fill silos with. Didn't have to listen to a tractor. Tractor wasn't in the way while driving loads on the blower. It also had just as much power as any 100hp tractor we could have ran on the blower. You can't even pay for the oil in the tractor with how much it cost to run those electric motors.

I know its not exactly what you are referring to but if you have 3 phase avaliable it is most certianly worth looking into switching to electric if your filling a couple silos.
 
I applied for a herdsmans position at a dairy up in Kaukana, Wis years back that used electric motors to fill all their Harvestores and the Slurrystore. It was awesome to see the blower run with out a snorting diesel working till its tongue hung out. It was just astounding to think just the movement of electrons could throw haylage 80 foot in the air.
 
The electric motor certainly would be the way to go. There has been talk about the power company bringing 3-phase out this way but it hasn't happened yet.
 
I thought I would try my 9" or so disk behind our newer Kubota 5740 in the field one time. I thought to myself that it should be able to handle it just fine--turbocharged, MFWD, etc. I was making it cut as much as possible, and it seemed to not like pulling it uphill. So I swapped over to my old Farmall M to see what the difference would be for this specific day, soil conditions, etc. The M walked all over that Kubota even though I would guess the Kubota has more "horsepower". Yes, it was a hydro and you loose some, but that good ole M had the torque to out do that day. "There"s no replacement for displacement" I learned a long time ago.
 
the old tractors had more weight and the horsepower wasnt being used as much on (air, heat, power steering, hydraulics) but as far as stationairy work obviously a tractor with more horsepower will act like it has more horsepower. wouldnt that make sense?
