Re: (ET) speed control

[Dean Stuckmann <dstuck lakefield net>]

I installed one in my E-16 this spring and I’m glad I did. I wish I had 
done it years ago. 

It was a bit of a project to design the throttle linkage as I wanted to 
maintain the stock hand throttle along with its built in reverse switching 
(no separate toggle switch). I also wanted to have the same speed in 
reverse as I have moving forward even though the reverse gate is so much 
shorter. I’m happy to report that I achieved all my goals. The motor 
control is amazing!  

However, there are a few things to keep in mind.

 - I found that there are multiple installation diagrams out there, and 
that they are not all the same. (Some specific to the E-20 but not the 
same either). If the 200 is compatible you may be in better shape than i 
was. Jim was helpful getting me through it though. 
 - You are probably looking at closer to $600 by the time you add the 
throttle pot, HD contractor, and other misc items.
 - Field weakening is available in the Alltrax but it is turned off by 
default. When its off, the ground speed is reduced by around 35%. That may 
not make a difference to some but I’m probably going to go to a 4” motor 
pulley (3” is std) to speed the tractor back up again. You can program the 
controller to engage field weakening, but its an all or nothing setting. 
Its a bit harsh when engaging, and more so when disengaging upon throttle 
back. I tried it out, but immediately turned it back off. It would be nice 
if the Alltrax/pot could gradually apply the weakening.
 - When I installed the controller I mounted mine upside down so that I 
did not have extend the high current leads. 
 - The controller does not seem to hold back the motor on down hills as 
good as the old setup but its not bad. Just something to be aware of. 

Again, I glad I did it. I’m no electrical wiz but with some time, Jim’s 
help, and lots of triple checking, I had it working on the first try. 

I don’t think that I can post pictures or videos of my install on the site 
but I can send them to interested parties if you want.

Good luck!
