Side View of the tractor, with front attachments created by David Grau at Valley Oak Tool

Here is the hydraulic manifold, that controls the hydraulics. We used a hydraulic Pump from a former truck of Richard's that had a dump bed on it. 

Dash board, has an Amp-meter and volt meter, along with  a light to let you know when it is on. The throttle is to the right. 

Here is me standing next to it at the SlowFood lunch.

Update Bomb

Due to school and finishing up this I haven't had much time to update, so here comes a big one.

Here's the motor wired in and in it's place. fits very well and feels secure.

Here's the motor controller in its proper place. This takes input from the throttle and converts that into a PWM signal (basically it controls the speed of the motor based on the throttle) to be sent to the motor. 

Haven't gotten around to posting in a bit, so here are some tardy posts.

With the cable crimper and cable cutter I began making cables for everything, Theres alot of work that goes into this.

Here is the first time we "fired up" the tractor. Still in Proto mode, just wanted to make sure all my wiring was right. 

BATTERIES ARE IN!

Got 4 12 Volt deep cycle batteries from a local company here in Chico called Energy Masters. Really helpful, and American made batteries. These things are HEAVY, but they fit the battery box so right :)
