Re: (ET) restoration pics

Tim, I still have the cutting problems you mention.  I started a thread a couple of months ago and many others commented about the same thing.  Still, others say theirs is very good.  I'm not sure what to think.  Is their's really good, or could it be we are too picky?
I'm not sure.  I've wondered if this is a design flaw caused by the overlap between the blades being to small.  I sure would like to fix it.  Having used the Electrak all summer, I have found only three things that I thought could have been improved upon.
 
1.  The poor cut quality of the deck.
2.  Poor lift design that makes it impossible to lift the deck at the end of each row (which would facilitate turning).
3.  First gear is too slow and second is too fast for cutting with the cruise control.
 
Having said that, I still really like my tractor.  It's otherwise a great machine.

I too have many restoration pix and a new schematic of my E20. 
 
I am currently using a 120 amp PWM controller (with reverse, acceloration/de-acceloration ramps, potentiometer foot control, regen braking, etc) and a combination 30 amp battery charger with a built in 3,600 watt power inverter (can almost run everything in my house in the event of a power outage as well as every power tool made that runs on 120Vac up to 30 amps).   For field weakening I have a fast/slow dash switch that switches in 50 ohms @20 watts in series with the field while still retaining full PWM speed control in either switch position.  Also, the field is powered up when the disconnect switch is closed which then enables me to sit on a 40 degree hill in LL without using the brake (dynamic braking). 
 
During my first mow through 6" of plush grass in D1,  I noticed a slight uneven cut aproximately where the blades overlap.  I have the new rear discharge deck set at 3" height and the blades are razor sharp but I think it might be the lack of lifting issue earlier discussed.  Maybe I'll try the Gator blades. 
 
I would also like to thank Bill Gunn for stocking the replacement parts for my 30 year old tractor as well as thanking many of you who offered your wisdom and experiences.

I've got 45 pics of my I-5 Elec-trak restoration from this spring.  They total 34 meg.  If anyone has the web space, I'll be happy to share them with the group.  I have them zipped and ready to send.  It was quite a job, and the photos turned out great.
 
Thanks,
