"Well I'll be danged! those are rare as hens teeth!"

Many thanks for that information, and no, I don't have a direct drive D3 but would like to get one...

Some pictures of one for sale for 16k in Spain. Picture of right side shows forward reverse lever in the u-shape slot by the operator's left hand. I don't see a picture of the clutch unless it's a function of the reversing lever. It also shows the 540rpm pto and the 3-pt linkage. Other picture shows the 5 speed gear shift in the center between the steering pedals. I didn't realize this model from 1990 was turbocharged - I wonder how many hp.

The D3B 2PCxxxx SA, LGP has a turbo 3204 direct injection rated at 82 DBHP and 101 engine hp. and were produced from 1985 to 1990.
Even rarer is the extra drive for either a winch or pto.
Regular D3 3204's are all 70 hp.

We have 2 d3bs . One is a 3f1r 24y lgp tag on top of engine says 65hp.1982 model
The 3f3r 27y standard track says 75hp on engine.1988 model

Looks like a hybrid D2.
