Serial # 2766, picked this up yesterday, came with tire chains, snow blower, dozer blade and mid mount mower deck.

This is one rusty tractor. The only thing holding the rear battery box on is where it attaches to the foot borads.

035.JPG 043.JPG 033.JPG

These EGT120 tractors came with 3 speed trans-axles and a single drive belt, but this one has a 4 speed trans-axle and a double drive belt. ???
Serial # tag says it's an EGT120.

The snow blower is a parts unit. Rusted out auger and it's seized.

The Dozer blade has very little wear on it, the angle adjuster latch is seized, looks like it can be freed up.
This is the best part of the whole deal.

The mower deck also is in pretty good shape 2 motors turn the 3rd is seized. Housing is covered in rust but solid. this is a side discharge deck.

Even in-spite of all the rust there are spots that clean up really good.

The 2 things that caught my eye when I first saw pictures of this deal were the front impelment mounting bracket and the side discharge mower deck.

It also had the wide 2 person seat on it that is rotted away.

Not sure what I'm going to do with the tractor but the mower deck gets fixed for sure, it fits my EGT200.
The snow blower is for parts, what ever I can take off it that's good.
The dozer blade I'll either sell or put sides on it and use it as a snow pusher.

Doug , I too have an EGT120 with 4 speed transaxle and double pulley . Any number of explanations could apply .If this happened at the factory the most logical would be - " get it out the door " .The plus side is an upgrade with a field winding motor is easy.

Parts books show single pulley and I can't find any mention of an optional double pulley anywhere.???

The parts books for New Idea are not entirely accurate .I have high output armatures for mower motors that the book shows as standard . Geo may have corrected lists or parts advisories that may surface . But I agree , the EGT120 wer supposed to be 3 speed single groove pulley .

Sparky in your opinion what is the most powerful motor they used on the whole line of electric tractor product at the the time?
42" Snow Blower motor, or the Tiller motor, or something else?

I have not got up close to a tiller motor but for pure ability to take punishment it gets my vote. If you caught my discussion of cable 00 over there , I hinted that the batt pack would need a little protection from punishment also.

All I know is that the
38" snow blower has a 90amp breaker, that would make the motor max at 4.3hp
42" snow blower has a 105amp breaker, that would make the motor max at 5hp

If the batteries can hold there voltage and the wiring can deliver the amps.

I don't know what size of breaker is used in the tiller.
E20s, I5s, EGT200s drive motors have a 105amp breaker on them also.

Could they have gone to a double belt because of slippage?

That could be. The torque that can be generated by the electric motor for brief periods under load, and before the breaker would trip, would be much higher than indicated by the continuous HP rating. I'd really like to see one of those electric tractors up close. I'd also like to own one but have never seen one down here. There seem to be quite a few in your area Doug.

JDBrian- Just never thought of you being in Canada as "down here" .... :D since you are "way up there " to me :thumbs:

Doug looking good! Nice goodies too!

I need a good electrical guy to guide me through getting mine running........I am better at someone showing me how to do it , than telling me how to do it or reading how to do it.

Yes, I'm north of most of the US but not all as I'm at just less than 45degrees north. I was thinking of Doug "up" in Ontario.

The larger tractors, E15, E16, E20, I5, EGT150, EGT200 all had stronger motors and double belts.
The E12, E12s, E12m, E14, EGT120 came with single belt.

The E12s and the E15 have the same drive motor but the E12s uses single belt and the E15 uses double belt. Don't know why this is.
