In a separate thread I have been asking for advice about different ZRT's and was focused on the Phazor 19/44" until today's experience. I test drove a unit today and found the IZT, or trans-axle if you prefer, to be too loud for my liking. I like the basic layout of the mower, deck size, and trim edge. But I would also pay $500 more to get separate pump and drive motors if that cures the noise issue and improves the units handling response. The question is: Where is the Phazor design going for next year? Will the unit with changes still be under $5000?
