Hello,

I've searched the site but can't seem to find somewhere that compares the various ZT transaxles. I'm in the market for a Zero Turn and wanted to be able to better compare units based upon components and features.

Any help would be greatly appreciated.

MDVDuber,

I'm not an Expert but have done a lot of research about the same question. Many of the Hydrostats are made by Hydro-Gear. The numbers refer to how light or heavy duty the Hydrostats are. Most residential ZTR mowers use the EZT units and the more expensive "Acreage mowers" have the ZT-2800.

High dollar commercial ZTRs use Scags, Exmark Etc. use heavy duty Hydrostats.

Her is a link to their website. http://www.hydro-gear.com/LawnGard/

I"m in the same boat and would stay away from the EZT since it is non serviceable. ON the ZT's you can change the fluid and filter. I'm not sure what your price range is but the cheapest mower I've found with separate pump and wheel motors is the JD 425. It however has a 11 gauge deck. That is what you run into when you try finding a cheaper ZTR. They have to cut corners to keep the price down. The Hustler sport has a nice heavy deck but I believe it uses the EZT trans. Now Gravely makes an XL 42 which has a 10 gauge fabbed deck and a kawasaki motor with the ZT 2800 for around 4K also. If it drives ok it may be the best deal out there.

Thanks for the replies!

I found the Hydrogear website- but could only find info on the ZT2800. Most of the units I'm considering are in the 5-6K price range and feature either the 3100 or 3400.

Based on local sales and service my 3 best options appear to be Gravely, Hustler and Dixie Chopper. I'm down to nuts and bolts - or engines and transmissions as the case may be....

While searching through the forums here I found someone who said the 2800 and the 3100 were the same unit? Not sure.For that amount of money you should be able to get a nice residential,light commercial Z. MY pop has a hustler fast track 54 and it is a nice mower for the money.

Thanks for that link. I've been trying to figure out the differences also. There are youtubes on the other grades available on this page as well. Interesting that they consider the 3100 as commercial grade. They are available on the Gravely ZT HD which can be had for around $5200 and has a one year commercial warranty. Still considering a Bad Boy, though.

2800, 3100 basically the same with the 3100 having a little more displacement. The 3400 is larger in shaft size and in displacement
and is rated full commercial.

My Gravely guy, who is technically proficient, told me that the the 2800 has stamped gears, and the 3100 and up have cut gears, which theoretically should make them more rugged.

Here is a link that relates to that subject. It begins about half-way down the thread.

I liked the old thread, the only thing I don't agree with is a customer having to buy a pump.. We rebuild the ezt's (can be done 70% of the time, izts are a little better on the percentage), and we charge between $90 to $150 a pump. For the customer they would prolly chance breaking them open to potentially save $800 bucks or so... They are so easy to rebuild, most of the time its just the rebuilt kit is all you need, bearings, gaskets, and new oil.

Thanks for the link as well! That was a perfect explanation of the differences b/w the two models.

Two of the mowers I'm considering having the same FR691V engine, but one has the ZT-2800 hydro's while the other has the ZT-3100 hydro's. Both mowers are within $100 of each other price wise so I think that would tip the scale in favor of the mower with the ZT-3100.
