I looked up the full specs of the Hatz 23 HP 2E40 engine on the Hatz website as this will fit into the PT425 or PT422 tub. Seems like a pretty decent little diesel.
One concern for those using the machine on slanted ground....tilt. The engine is rated plus and minus 25 degrees along the axis of the crankshaft which is great, but only 17 degrees one way on the side to side tilt. (The other side is 30 degrees.) Steep slopes would be fine in one direction but wreck the engine coming back. Flatlanders will have no issue with slopes, but might still have to watch the PT-Pucker tilts.
Since our machines are much more stable than most tractors, we need to be concerned by the engine tilt specifications more than most as we operate our machines on more sever inclines than most tractor owners....because we can!
Speed is a reasonable match at a rated 3600 even though typical use is to 3000. Occasional use at the rated speed of our pumps and thus full power is possible but fuel efficiency drops off rapidly above 3000 rpm.
Cold weather starting will remain an issue and will likely require an input air heater.
All that said.....when/if the Subaru fails, this will be a serious contender.
The other engines from Hatz are either too small or too large for my machine but the G, L, or M engines may offer options for the big machines.
