cruze, Be careful with the Husqy model designatioin and pricing. I found a lot of dealer confusion on what model has what trans. There "were" 2 non slip diffs available , I believe. One a "limited slip" similar to automotive options where no switch action is required. The other a true locker ( I have) with a dash-mounted switch (K 66) . At the time I purchased the locker was not available with Kaw, so I reluctantly bought the Endurance Intek ( so far so good). The price is also a clue. My purchase was on an aged showroom queen discounted for cash. The list price was well above $3000. Take a look at the Husqy forum here.
It's called "analysis paralysis."
Engineering-types are especially prone to it.
Without meaning to sound condesending at that price, pick the colour you like most or the one with the longest warranty.
All of them have been downgraded as much as possible to make the price as low as possible so as you have already noticed there is 5/8 of SFA difference between any of them.
The only real difference is the deck & blades and you need to talk to some real consultants to find which combination will mow the grass that you have best .
IF you are pushing snow and dragging a 1/2 ton roller then consider a compact tractor because all any residential garden tractor is going to do is empty your wallet
There is a lot more different in the JD for the extra $3000 than just the trannies.
JD have a different specificationfor their engines, they are a cut above the standard, they also press the frames from thicker steel and fit a lot more bushes where control shafts go through holes so they don't flog out oval.
You do not see it in a spec sheet but I do when I get under the mower to fix something.
Your eyes seem wide open enough, just don't be dissapointed when in 3 years the mower you bought starts to fall apart.
A cheap tractor requires consistant & carefull maintanance if you expect to get good service life out of it.
Well good for you finding a Kaw/K66 locker, 'cause I could not one year ago. Hoping the Endurance Intek holds up. I also wanted a compact tractor, but just could not justify the ?$10K used, and here a really thin used market, unlike the Midwest (Iron Search).
BTW I am just finishing up a year long eval of my Husqy. Take a look at "Impressions..." here in the Husqy forum. I am satisfied overall . It does use more gas being heavier, but the locker has already helped out. No reasonable bagger,though.
