I am selling four Toro 21" prolines. They have each been a full time machine for a year, and a back up machine for a year. I will be replacing wear parts on them this weekend. They will have new wheels, new wheel gears, new height adjusters. (about $120 of new parts). They go for $500 on e-bay in the spring, so I will be looking for approximately $475 - $500 depending on the machine. Local pick up / cash only / you can come over and mow my yard with one to before purchasing (to make sure it fits you ). PM if interested....otherwise look for them on e-bay in March!
