Combines horsepower

Just a thought - I would suggest that you change the corn head instead of the combine. Change the head to the Geringhoff RD and I would expect power use to go down enough to make all work better.

I have a 84 N7 and three years ago I bought a 95 R62 with the air diesel, both engines have about 2400 hours on them and both are rated about the same HP but believe me the 516 cubic inch N7 is no match for the almost 800 cubic inch German engine--- I guess the horses are a lot bigger in Germany than they are in the United States!!!!!! The R62 is a very reliable machine but I could not say that about the N7 as I worked on it all the time. Good luck

Metric horses [ horse power ] are just marginally larger than the American horses but a lot of the differences are in how they are measured. I may stand to be corrected here but I believe that US horse power is measured with items such as fans [ 20 or more horse power on a large engine ] water pumps, alternators and even oil pumps in some cases, being driven independently from the engine being tested. This essential ancillary equipment can soak up a swag of power. When this gear is hung on the engine in an actual application, the available horse power is greatly reduced from the claimed total engine hp. Metric horse power measurement requires most of these items, such as fans on aircooled engines and etc, to be driven by the engine being tested and is a better reflection of the actual power available. Cheers.

I believe from what I have been told that these deutz engines can easily be turned up to the same power as a 72.

You may be on to something. Maybe Europeans measure power with fans etc hooked up while Americans measure the bare engine. We cant blame the metric system because the metric unit of power is a watt or in practice, a kilowatt (kW). And going one step further, 200 hp = 150 kW.

i beleive he said the 62 was only rated at 225-240IJ any commentsIJ august wieser

I forget which year they changed but the early 62's had a naturally aspirated Deutz at 228 hp. The later ones had turbochargers and were 260 hp. (The first Cummins were 240 hp, then went to 260 hp, now 285 on the R65). A horsepower is the same between here and Europe but the test standard is a little different. They both have the engines set up the same except with a Deutz, the cooling fan is included and with a water cooled engine it is not. So the 228 actually put about the same power to the clutch shaft as a 240 hp liquid cooled engine. Europe uses a little stronger fuel and tests it at a cooler fuel temperature than the US so actually the same engine in a Europe (DIN) test will show more power than in a US (SAE) test.

i believe this model is the 225 non turbo how were these engines on fuelIJ so if my N7 is short on power in some apps then the 62 will be tooIJ thanks august wieser rosholt, sd

Take a quick look in his engine compartment. If it is a 93, it about has to have the twin turbos. Just look for the turbos. A couple of years ago, I had a very new R62 (285 hp) running in the same field as a very polished N7. Both had the same size of headers and were running in good wheat. They were a dead heat all around the field. Switched drivers and still had the same results. Keep in mind that th 62 had a lot of rough chrome in it yet which when polished will increase capacity. A Duetz V8 with the turbos and in good mechanical condition will run very close to the newer R62s. When I say good mechanical condition, I mean engine fan, injectors, valves, timing, etc. HTH kelly

i thought the 93-62 had the 900inch naturally aspirated engine and the 72 had the twin turboIJ IJIJIJIJ august wieser rosholt, sd
