Maybe you can answer a question I've had for sometime. What is the
relative efficiency of hydraulics, belts, gears and chain drive?
You've given the hydraulic answer. Care to take a stab at the others,
please?

STAB, yes ... feelings based on things I have seen and heard ... NO
HARD FACTS to back this up. (I looked and failed to find support)

hydraulics TOTAL ... ~80%
v belt, 90-95%
tooth belt, 92-97%
spur/bevel gear, 96-98%
worm gear, 25-80%
chain. 96-98%

lesser ratios (nearer 1:1) are more efficient.
Thanks.
