My 1650 needs more electrical output!!

Easy one! Remove the gas tank, fab a bracket for the alternator, redesign the drive shaft end with a pulley...Now fix the tank over the hood...

For more of a "cub" look you could get a used starter/generator and bracket. Take off the side shields, mount the s/g and get 169 decals for the hood.

You said originally this a dedicated snow removal machine. If that's the case is it possible to mount the alternator underneath the tractor and power it with a pulley off the drive shaft? That way it's out of view and since it doesn't mow, it's not in the way of a deck or anything.

Can get electric gloves to go with!

I have try to figure out this problem, looking to rewiring the stator but even if I get success, I still need to replace the regulator, the wiring, and possibly the ignition switch since I don't think the OEM one can handle 25A. Of course you can design a auxiliary relay to handle that but it's a lot of work and I prefer K.I.S.S solution

Plug the heater direct on an extra or bigger battery and your good to go, My Optima "Redtop" I salvage from my Diesel Jeep can old a 25A discharge for 100 minutes, enough to power you heater for a few hours (thermostat control wise) and this cost me NADA!

PS: My Optima is 8 years old and start my tractor like the engine run to catch a deer! The new Optima are fab by Johnson Control and don't worth crap...Buy a Sear Platinum they are made by Odessey.

If you add a bigger alternator, as long as you wire in your extra accessories to the battery, the only part of the existing wiring that wouldn't be heavy enough is the charging circuit wiring. Nothing else is going to draw "extra" amps just because they are available.

Use a Kubota alternator and drive it off the back of the motor on the pulley before the driveshaft. I don't know how many amps it makes, can't find a spec, but I'm sure it is no less than 15A. Usually they are around 15-30A. Or, like what was suggested earlier, use a 30A Kohler stator. (Click on the pic for a link)

i was eyeing up this alternator also. Nice and small easy to hide. pretty sure quietlines don't have a pulley off the back of the engine like the older ones did. i will check for sure though. Do you know if this alternator requires an external regulator? can't figure out why it has two wires coming out of it. Does it work like a stator on a k series?

[DoubleO7]

per J-Mechs link it says:
OEM(s): Kubota
Voltage: 12
Regulator: E/R
Weight: 6 lbs. / 2.72 kg

I suspect E/R = external regulator.

I saw where the O.E.M. of this is pushing $300 on some webpages, geez.

[J-Mech]

Yes, Double07 is correct, it is external regulated.
If the 1650 doesn't have the pulley, just change the driver to the pulley style. I'm pretty sure you don't even have to shorten the driveshaft to put it in. Lew might know. But even if you do need to shorten it, that's no big deal.

That little Kubota alternator would work on a hydro,just run it off the rear output shaft on the hydro unit.I am not sure how much space is needed for it though.
I would also keep that charging system isolated from the oem one.

We were talking about driving it off the rear of the engine with the pulley style adapter like was used for the hydraulic lift units. Are the two hubs the same length Lew? I think they are....
