(ET) Another industry publication article on electric tractors

[Darryl McMahon <darryl econogics com>]

Hmmm, something is changing out in the world of expensive diesel fuel. 
Is industry really waking up to smell the electrons?

Anyway, from this article in Assembly magazine which also covers a 
number of manufacturers and models, I appreciated this quote from Doosan 
Bobcat:

'Traditional hydraulic components have been completely replaced with a 
drive system that consists of electric cylinders and electric drive 
motors. The machine also uses only one quart of eco-friendly coolant 
compared to 57 gallons of fluid in its diesel-hydraulic equivalent 
counterpart.

'The all-electric platform enables instantaneous power and peak torque 
available at every operating speed. Operators no longer have to wait for 
the standard hydraulic system to build up power.

'“We went all the way in that direction, because we didn't think we 
would get anywhere near the runtime necessary if we just replaced an 
engine with a battery pack, [due to] the inefficiencies of the hydraulic 
system in general,” says Justin Odegaard, acceleration manager at Doosan 
Bobcat. “That was really the big push that made us go down the 
all-electric path rather than just electric powered.”'

'due to the iefficiencies of the hydraulic system in general'.  I never 
thought I would see that phrase in print in general distribution media.
