    I've read several posts about people having hydro/wheel motor problems with their Super Z (myself included). Someone stated the 21cc pumps may cause overheating. Could the 21cc pumps be replaced with 16cc pumps for more torque, less groundspeed, lower temps and less problems.

    Hey, we replaced a pump and a wheel motor with just a lil over 1000 hours, I will never buy Hustler again. Good luck, I'll watch the post for response, but poor dealer support and I think we got taken on the wheel motor replacement.

    Tell me what size engine you are running and I will explain what is happening to your hydraulics.

    I've had 2 1st 24hp Honda 2nd 27hp Kohler. I really loved both of them just too many issues. I also think the 21cc hydros overwork the engine hence why I'd like to to see 16cc used.

    Are those Parker wheel motors or Hydrogear wheel motors? Both sides weak? What do you mean ''Burnt up"?
    I've seen quite a few problems with Hydrogear motors , but the Parkers are close to bullet proof.

    The short answer to your question is absolutely yes.

    It's not a direct drop in though. The PW (21cc) pump is physically larger than the PR (16cc) PR pump. The mounting flange on the 21cc is larger than the 16cc. The swap would require some fabrication work.
