Painted, controller wired up and tested, a few things to finish up before drive testing. :bananas :bananas :bananas

TEST DRIVE :dancingbanana: :dancingbanana: :dancingbanana:

Took it for a drive toady, first thing I notice is how smooth it is and how slow you can get it to go even in top gear. It's not jerky like my EGT200 is. Top speed is less, it seems to go slower in all 4 gears compared to the 200, but it can climb a hill in top gear that the 200 can't, power use meter always in the green. Changing from forward to reverse is quick, works like a shuttle shift.

Everything works except the lights, haven't finished wiring them up yet.

If I had to use 1 word to describe the tractor with the Alltrax controller in it would be SMOOTH.

I like this thing. :dancingbanana: :dancingbanana: :dancingbanana:

Wow that looks great. Just in time for spring! What tires do you have on the front? I like the looks of them. I might have to reread this build as i have an Alltrax waiting to be installed. But i've been timid to stop down that road.

Front tires are 4.00 x 8" tri-ribs, steers easy and I find they grip pretty good.

Doug, that's looking really good! I too like the looks of the tri-rib front tires.

The E15 uses a smaller motor pulley than the E20 (EGT200), so even at full motor speed the groundspeed of an E15 will be less than an E20. I'm not well versed on the Alltrax, but it's my understanding that the way it does (or doesn't) do field weakening results in a slower motor speed than the original controls. You can always compensate for that with a larger motor pulley, if you'd like to get that speed back.

BTW, the original control cards from this machine were rebuilt with new capacitors and are currently alive and well in a good friend's E15.

Thanks Nick good to hear those parts were used.
I talked to Jim about the Alltrax and found out that they come shipped from the factory with the "Turbo" (field weakening) feature turned off, can be switched on by reprograming which anybody can do.
So the way it is now at full throttle you get max torque with full field voltage. That's why it feels a little slow but has lots of power in top gear . 1st gear is ridiculously slow.
Putting on the larger E20 pulley would be nice, a little more speed and I think it has the power to handle it. Others on the GE sites have said the same thing. For me I find myself wanting a E20 motor with the larger pulley, then I have an E20 tractor with the Alltrax.
I think I'll leave the Turbo feature off for now.
It has been a learning experience and a fun project.
Thanks

All that is left to do is glue on the red reflector and get some seat cushions.

I took E15 with a 10" Brinly plow down to a Plowday event in PA, wanted to see what it could do. Saw some old friends and met some new ones, the weather nice and the fields good for plowing.
I ran the tractor at least 2hr maybe 3hrs total and at least 1hr pulling the plow. Found that when in L or 2nd gear tractor has lots of power but moves a little slow, in D1 or 3rd gear it still has lots of power and moves a bit faster power use meter in the middle of the green, in D2 or 4th gear it can pull the plow, speed is faster, power use meter is at the top of the green and it feels like it's struggling, D1 or 3rd seems to be the best gear to use.
Traction was not a problem I had Carlisle All Trails on with NO extra weight added.
After I got home I checked the batteries to see how much charge was left and they were at about 50%.
I am really happy with the way it performed these GE tractors can do it and looking forward to going to another Plowday. Thanks to Alan for the pictures.

Beautiful pics!

I have to ask, how many runs of the field did you make, and how did the batteries hold up?
