EcoRenovator - View Single Post - Recycling old (2009) Electric 'push' Lawn mower

The new insulator isn't coming until next Wednesday..

I got bored this morning and installed the blade using the old insulator. It's only slightly damaged.

My handy torque tool isn't adjustable, and I think it's pre-set to about 58 ft lbs.
So, I was careful not to run over any stumps during my little test mow.
This E-mower is light (light enough for a small woman to use) and it cuts pretty nice.

I'll have to get out a real torque wrench when I new part is delivered.

Battery power? I was looking at the diagram and there appears to be a full wave bridge rectifier between the AC and the motor.
So, I'm thinking the motor is running on 120 hz pulsing DC with a 170 v peak.
