Yes, it's a 3 cyl n/a cat engine. I am having difficulty getting the specs from Ferris (email limits at work).
Here is the information from the flyer:
Looks like Diesel Progresses specs were a touch off, especially on the torque.
The new Ferris IS 5000Z mid-mount zero-turn mower boasts
of the most powerful, reliable, economical performance in its
class. Featuring a newly-designed four-wheel IS independent
suspension system and 31. 5-hp Cat long-lasting diesel engine,
the IS 5000Z is the ultimate mowing machine.
The IS 5000Z offers four-wheel independent suspen-sion
with adjustable front shocks. This next generation of
independent suspension from Ferris means the benefits of
IS—operator comfort, speed, extended mower life, traction
and consistency of cut—are more apparent than ever before.
A 31. 5-hp,three-cylinder,industrial-grade diesel
engine from Caterpillar,Inc. ,powers the IS
5000Z. It features a 6000 hour engine life rat-
ing,1500 CC displacement and engine torque
of 55 ft/lbs at 2800 rpm.
... with the power and performance
of a Caterpillar diesel engine.
