This machine was produced by Olathe and the design was sold to Toro. Toro provides replacement parts. It's ground driven hydraulic pump operates the brush and the belt. There's a 2 lead pigtail on the tow bar. Power the pigtail with 12VDC and the brush and roller engage via a solenoid valve. It has 6 tires to spread the weight out so it doesn't leave impressions in the green. The 4 tires underneath it are new. I have a test lead with a matching plug, some alligator clips to hook it to the battery, and a switch to turn the belt and brush on and off so I can demonstrate it. This is ready to go to work. If you have flat enough ground, you can pull it with a turf cart, but if you have any substantial hills it's best to use a workman or a progator. We've done it both ways.
