Kubota Car

[4570Man]

I bet it’s half the hp and double the radiator and fan when it’s an industrial application. A light truck or car could never run at it’s rated hp very long. The 40 hp Kubota in discussion can run tens of thousands of hours at rated capacity.

There really is no difference between a commercial and noncommercial engine. The commercial engine is just de-tuned to run longer at a higher duty cycle.

For example that kubota engine has the ability to make double the horsepower, but at a lower duty cycle. Also the 6.7 powerstroke is the same engine, both showing up in the medium duty trucks (F550-F750) as well as the light duty trucks (F250-F450). The medium duty trucks are detuned to have a higher duty cycle because of the weight and axle gearing.

Actually more cooling is needed on a lower duty cycle engine than a continuous duty cycle engine. The thermal variations on a non commercial engine are much more extreme than a commercial engine that runs at the same RPM all day long.

You’re wrong about the cooling. Equipment and heavy trucks have way bigger radiators per hp than light trucks and cars. The 6.7 you mentioned in the medium duty trucks will have a bigger radiator than its light truck brother. Probably to the tune of twice as big a radiator and fan vs the pickup.

Automotive engines sold as industrial have far lower ratings. The V10 Ford is typically used on 75-100kW gensets meaning it’s topping out at about 135hp and that is with a turbo added.

The V6 maxes out around 47kw which is about 64hp. Before I ignite the Ford Chevy debate, it’s no different for the GM industrial versions or the old Chrysler products.

Even at the lower rating the max life of an automotive engine in a genset is 10 - 20k hours if well maintained or about 2 years of continuous operation. The generally accepted conversion factor is 4000 hours equals 240,000 miles at light load cruising speed of 60MPH.

A B5.9 or QSX15 will run 30-40k minimum. I’ve seen Kubotas run 60k hours. Again, that 5.9 in my truck is 325hp, in a genset it’s 175hp.

Stationary cooling systems are larger due the fact you have no airflow except the engine driven fan. Truck cooling systems are typically larger to support long periods of idling or low speed operation and to have reserve capacity to allow for the system to age because they are simply expected to last longer.

Just my bit of insider info.

A company called Aixam in France makes small cars with Kubota 2 cylinder diesels. They are owned in part by Polaris.

Well that is cool, although I would not one of those ones, LOL. But I'd take a custom hotrod or pickup with Kubota power.

The seats made me laugh. Any pictures of the entire car?

I haven't been to the last few shows. I've had cataract surgery and various other doctor appts. plus the transmission went in my classic car which I've had rebuilt. Finally went to a couple shows looking for the car and found it at today's show and got some pics of the entire car.

What is the top speed, is it hydrostatic. What is the Body main from?

Owner claims top speed is close to 75 MPH but wouldn't recommend sustaining at that speed. Transmission is a 5 spd. manual. Has custom built frame, Body and fenders all fiberglass. Engine HP is 55. Claims to get 50 MPG, Owner says real life MPG is 35-40.

all that work and no PTO?
