The biggest issue with diesel power is weight. This is true in light trucks, and in ZTR's.

A Kohler V-Twin weighs in just under 100lbs dry.

A.... (lets use Kubota) 3cyl 1L Diesel is over 200lbs dry. Now add 3 more quarts of oil, a radiator, hoses, fans, and coolant.

Adding 2-300lbs to a 1300lb ZTR is a BIG deal.

Especially when we have some rather excellent air cooled V-Twins these days.

This Kubota Diesel is 25hp and ~45lb/ft of torque. You can get a gas powered V-Twin that will blow it's doors off when it comes to power and RPM maintaining torque.

ZTR quality continues to improve, but for the most part, a ZTR is pretty worn out after 3K hours, no sense putting a 10K hour engine on a 3Khr ZTR. Especially when the diesel is adding thousands to the MSRP.

I'd love to have a little 1L diesel that's TURBO'd to keep torque up and maintain RPM's better. Don't know why manufactures dont explore this a little further.
