Mowing Kub.B5100 belly mower drive?

[allenr]

On Friday I picked up my second B5100. This one has obviously once had a mid mount mower on it, going by the linkage from the arms to below the footboards.

I've seen a picture of a 5 or 6100 with drive to a mid mount mower coming from the front of the crankshaft.

Can anybody tell me more about this drive arrangement?

My new (S/H) one has an extra switch below the key which appears to be wired into the harness (loom) and has spade type fuses which surprised me.
The first one hasn't got a spade connector anywhere - all bullet connectors.

Second one was claimed to be a 1987 model.

Front PTOs have an electric clutch mounted to the crank. Flipping a switch engages the PTO and spins a belt to drive the mower (or front snowblower).

So it has belt/s going down, does it then have a R/A drive and another belt or shaft. Or does the belt from the crank take a bend around a pulley?

My B7100 has a front pto with electric clutch. It runs my snowblower and my belly mower. The belt goes down to two pulleys to change direction. The switch on the dash activates the electric clutch to engage.

Does the Dynamo which these tractors were fitted with, have enough output to engage the electric clutch for long periods of time, without flattening the battery?

I'm planning to fit an electric clutch on the new B5100 to cut in/out a crankshaft driven compressor. On the old B5100 I fitted an alternator without even trying the dynamo only, as previous experience with a 12V sprayer showed that the dynamo output wasn't sufficient.

I guess the biggest problem in relying on dynamo only for the compressor drive is that the engine will only be running at 7 - 800 rpm whereas for mowers the emgine is probably revved up?

When you are using the electric clutch you are only energizing a coil to engage the clutch, so there should be no electric issues. Running a sprayer you are using a fair amount of battery energy so, yes, the dynamos on these things won't keep up with that kind of draw.
