The wording of live, independent, etc. may sometimes be confusing, but an Agriomatic equipped Neuss built IH tractor is "technically" characterized by:
- the two clutches are in series, not parallel.
- you disengage flywheel clutch (foot pedal): transmission stops AND PTO stops.
- you disengage Agriomatic clutch (hand lever): transmission stops AND PTO does not stop.
A peculiar aspect of Agriomatic is that it only provides for live PTO in low range of the transmission. The PTO can be used in high range of the transmission but is simply transmission driven. For most farm uses this is rarely a limitation.
The clutch of the Agriomatic is a wet multi disc and engages very smoothly. Easy to inch the tractor forward. Very robust clutch; IH even claimed it may be used as a temporary speed reducer by letting that clutch slip. Try that with a standard dry flywheel clutch!
Forgot to mention that, besides the two D430's that we had, we still have a 453 which is also equipped with Agriomatic. Lovely tractor with lots of power and a 3 cylinder direct injection ( no glow plugs!) engine. Its smaller brother is the 423 (very popular tractor, a dime a dozen) but has an indirect injection engine, similar to the older D-series.
Stay away from a D440. Blower/turbo isues!
