I think you need to do some checking Because it sounds like your talking about the Z master 2000 not the 3000. It also sounds like you maybe talking about last years models at those prices. The Z master is a lot better mower than the PZT, if it's the 3000 they come with a full 7 ga deck which is a lot more deck than the 10/7 ga on the PZT. The ZM also comes with separate pumps and wheel motors not the 3400 drives like the PZT. The ZM 2000 come with he 3400 drives. The new Z-Master 3000 can also be purchased with the new suspension platform and it has 3 coil over damper shocks that are fully adjustable for ride quality. The PZT-54 on the Husqvarna site list for $7699 and the Z Master 3000 will go for somewhere around 10K or better New.
