    Why would the 1025r have more pto HP than the 2025 and the 3025?

    I stopped at my dealer today and grabbed a 3series brochure for my brother in law and got a quote. Iíve been having 2 series and 1 series brochure since I bought mine. So I was just comparing them And thatís when I noticed it.

    1023e = 22.4hp and 15.3PTO
    1025r = 24.2HP and 18PTO
    2025r = 24.2HP and 17.2PTO
    3025e = 24.7HP and 17.4PTO

    Huh. Typical Deere weirdness.

    If you go look at the Deere web site and look at each model they say:


    1025R Eng HP 23.9 PTO HP 13.4 kW/18 hp
    2025R Eng HP 23.9 PTO HP 13.4 kW/18 hp
    3025E Eng HP 24.4 PTO HP 14.4 kW/19.4 hp

    Pick any 2 Deere documents and they can't seem to agree on much.

    If I had to hazard a guess, I would say that itís due to more of a parasitic load in a bigger, heavier tranny and maybe larger hydraulic pumps. I know the 1025 has only 1 pump for both implement and steering systems, what about the other 2?

    Oh, another difference I just noticed in looking at the brochures. The 1023E, 1025R and 2025R ratings are at an engine speed of 3,200 RPM. The 3025E rating is at 2,400 RPM.

    I added pictures to the original post.

    I also noticed the PTOís KW match on the 2025 17.2(13.4kw) and the 1025 18(13.4kw) and the 3025 17.4(12.9kw) is the lowest KW.
    Man this is confusing

    Always Look In the Manuals There Product Literature can be all over the Place John Deere Operator Manual | Parts & Services | John Deere US But 99% of the time the Manual will be accurate

    Man this is confusing
    The reason that it is confusing is that consumers like to think in terms of horsepower so that is what is marketed to them. HP however is a derived number which comes from torque and torque is what matters. HP = (torque * RPM)/5252 .. the magic being that number 5252 which itself is the byproduct of a number of conversions to convert the easily measurable (torque) to the definition of horsepower. Horsepower is defined as effort over time, specifically 550 foot pounds per second which, is a non-intuitive thing to measure. Torque on the other hand is very measurable, it is a twisting force and the units of expression (ft lb or NM or whatever) dictates how the measurement was arrived. We typically think in ft lb so that is 1 pound at 1 foot or 1 ft lb. If someone tells you that a particular 'thing' has x amount of torque you can intuitively figure out how useful it is. All that being said;

    The reason that the table you provided is confusing is that one of the factors in the equation (RPM) can change dramatically while HP only changes a little.

    Here is the same information but converted to torque. You can see that the 2025 loses a little bit of usable power over the 1025, probably due to increase in mass but otherwise the engine and PTO outputs make more sense than just looking at HP alone. The 3025, despite having the same HP as the 1025 is more powerful because it is making that HP at a lower RPM (so more torque).

    (the PTO output is dependent on the recommended PTO shaft speed, either way, the 3025 has greater potential output even at the same rated horsepower of the other units simply because it won't bog down due to the increase in available torque)

    Many years ago, I went with my neighbor to Sears where he was picking up a new air compressor. Whilst he was busy with the salesman, I was BSing with another salesman, an older wiser type. I asked him, regarding the air compressor, "How is a 5 horsepower motor supposed to run on a 15 Amp 120 Volt circuit?" He gave me a knowing grin and replied, "Them's Madison Avenue horsepower." 'nough said.

    Believe itís a different engine for the 3025E. Itís a lower revving larger displacement engine that is why it produces the same torque and horsepower at lower rpm.

    I think it's all Deere doing the Hokie-Pokie for regulatory purposes.

    The 3TNV80 in the 1025R develops max HP at 3200 RPM and that's the specs Deere advertises.
    The 3TVN88 in the 3025E develops it's max HP at 3,000 RPM. But Deere doesn't advertise those numbers. They use the 2,400 RPM specs instead. Why?

    By advertising the 3025E at 14.4 Kw/24.7 HP they are bound by the Tier 4 emissions standards for engines that are less than 25 HP.

    But Yanmar's charts show that the engine used in the 3025E produces just over 27.1 Kw/36.3 HP when you crank it up to 3,000 RPM. If Deere used the 3000 RPM numbers they'd have to apply the > 25HP Tier 4 standards and they would have been forced to outfit the 3025E with a DPF setup.

    They down-rated the 3TVN88 engine so they could keep the cost down on the 3025E.

    It's kinda funny. The 3025E, 3032E and 3033R all use the 3TVN88 engine. But if you look at Deere's specs for them:

    3025E = 24.7 HP @ 2,400 RPM
    3032E = 31.1 HP @ 2,500 RPM
    3033R = 32.2 HP @ 2,600 RPM

    Increase the RPM to dial in the HP you want to advertise....
