I'm not a tractor expert by any means, but most of what makes a tractor able to work so hard and well is the gearing. No need for V8 power when you are making better use of the power. You don't need to take a tractor on the freeway.

 

Good morning thinkers!!- Hope you fellers are well!- GRT- no, ha ha, i dont work in a salt mine- ( its my generic term for everybody's job- since i dont know where everybody works)-
I work in a large papermaking facility- although it is a union facility- the pulping process is a chemical nightmare! Its quite a place!
Stay safe, have a great day! ttyl!

 

Does this mean a pickup truck has more "power" than a tractor ?
Yes, the truck engine does make more power than the tractor engine.

How do they calculate the Torque on these machines?
Torque is the measurable value. Hp is calculated from torque and time. The formulae is Hp = torque * 5250 / RPM.
Torque is what a dyno measures then calculates the Hp from that measurement.

When dealing with automotive engines, those big Hp numbers only relate to how fast the vehicle can accelerate (and in a few vehicles the top speed achievable). The needed power to maintain speed is usually a small fraction of the power the engine is capable or producing. The average sedan would need ~15 to 25 HP to maintain 65 MPH on level ground. Larger rolling resistance (big tires) and increased wind resistance (larger bodies) cause trucks to need more Hp
One reason the tracktor needs so little apparent power (in relation to the truck) is due to its lack of need to accelerate quickly. It performs its tracktor duties by being big and heavy with tires that provide a huge footprint and the very low gearing to match. Many tracktors are designed to be able to send more power to the accessories than to the motivation.


Also, Good morning Rcairbear.

 

Mornin' Bear and Noobs.

 

Top of the morning to you White.

 

Ultimate,

I'm looking on specs for utility tractors roughly 80 HP models. They consume 18 L/Hour in fuel(diesel) ?
That's financially devastating !!!
Aren't "hours" in tractors measured in real time?
I've never seen a tractor owner near me top up his fuel tank with that amount even after 8 hours of work!
We're talking 60-70 L capacity fuel tanks too!

 

Need link to the data to comment on first question. I can't find fuel use data from tractordata.com, the Landini website nor the Perkins website.
I will say that using all 75 Hp output for an hour, 5 gals doesn't seem wrong if compared with a generator consumption.
Where I work we build custom equipment. As a rule of thumb when a generator is needed we assume 7.5 gal / 100Hp per hour. The consumption number you have is a bit lower than that so I assume that number is for full load of engine. This figure does include some for a reserve capacity.

The tracktor will use less fuel when less power is needed.
The travel gear usually does not need much power, the power (and thus the fuel consumed) is most used by whatever is attached to the PTO and that can vary greatly.

Hour meters for industrial equipment is anytime the key or switch is in "Run" position whether the engine is running or not.

 

Steeda just contacted me and said PDI is going to warranty my headlights. I woulda raised cain if they didn't. To literally last 3 months before it leaks is ridiculous.

GRF150.... hook your peepers on this video.

 

Might have a new color to add to Frankie this weekend. Trying to line up the picking up of a hatch right now.

 

So... Frankie will be wearing a Technicolor Dreamcoat?
