Moving forward! I purchased a front axle assembly from a Bolens 1050! Got it for $50 picked up. :)

 

Nice thing about this is the PTO shaft unit I have will bolt up to this, it will also give me the proper tab mounts for Bolens front attachments, and gives me clear direction to go with the steering system. I'm going to start making the adapter for the electric motor to transmission, then it's a matter of cutting and mocking things up!

More updates. I acquired a Reversing fused contactor block from a forklift similar to what my electric motors came from. Should help with the pto motor control. Also bought a pair of used Ford LGT100 12x8.5 rear wheels I'm going to adapt. Not to mention I have the 2x3 steel to start on the new frame. :)

My car is almost done... just another panel to carpet. wife has given birth to my 2nd.. and I may finally have some time to get on this project.

Bowdown, I am excited to see you regain your momentum on this project, as I am sure many are, and can't wait to see it complete.

 

I do have one question for you though. Where in the world are you going to find room for the batteries? I have seen the workings of  electric golf carts, and such, and the batteries are huge!!!

Ya they are. I have a 2d cad sketch of the frame layout. Monday I can upload a picture of where things are going to fall.

I'm also thinking that I may sheet metal the sides of the front in. That way I can keep electrical accessible. Will hinge it for hot rod hood look.

Basically a battery box for 2 12v floor scrubber batteries will go directly in front of the rear sprocket. It will hang down about 5" and poke above the frame about 3".

I am in the process of redoing my panzer right now, so mine is down to the frame right now as we speak. I cant possibly see how they would fit in there without cutting a bunch of stuff out of there, or making the frame longer? Here is a pic of mine with a standard lawn battery. That's without the rest of the stuff that normally would be in there.

Well I'm installing 2 electric motors not in the same OEM gas location. I'm stretching the frame 4". Also the tubes are going to be 2x3" box.

Ahh, I see. It will be interesting when done for sure. What do expect the discharge time to be with both motors running?

Thinking 75-90min. Not sure how much load will be on the motors doing the drive and mower deck. Going to install a couple shunts and meters to see.

Long gap here but the past few days during lunch I have made some progress on this project!

 

I cut up some of the 2x3 (.120 wall) tubing for the frame rails, and some 2x2 (.120 wall) tubing for the rear drive motor support, battery box support, and front pto motor support. I thought my work had some 2" OD tubing kicking around I could use for the Bolens front end attachment, but it's 2" ID so no go. I ordered up a 3ft short piece from eBay. After that arrives it's a matter of welding up the new frame structure. I'm thinking I will go period correct on the welds and stick it together... Maybe cheat a bit and use the mig for tacks. 

 

In the meantime I finished dis-assembly of the tractor to the point I need it to be... I removed the front grill, steering, rear fenders, lift mechanism, and cut the original frame tubes off near flush with the rear end. 

 

The new 2x3 tubes will rest on top of the rear end. I'm thinking I will weld a piece of angle iron on the inside similar to the fender mounts and bolt through the 2 brackets, tube, and fenders to attach the rear end to the frame rails. I'm also leaving about 1.5" overhang off the back of the tractor for a future rear 3pt hitch setup. 

 

Sorry for the lack of pictures. When I get to welding and mockup on the rear end and new front assembly I will be sure to snap some pictures!
