      • It's great...except for the transmission
      • January 12, 2015

      I want to love this mower....really. I've had no issues with it cutting my 1 acre of grass and hauling firewood around in a gorilla cart. However, the weak link in these mowers is the transmission. I've only got 30 hours on mine and the transmission is starting to whine loudly, even on level ground with the mower deck disengaged. So I started looking online to see what can be done. Apparently, these transmissions fail a LOT and you need to remove it from the mower to change the fluid. I've owned this thing for a couple of months now and I took it to the local JD dealer to see if they could fix it. They're willing to fix it under warranty, but say that the transmissions are weak in this model and they change them a LOT. I was told to not tow anything and definitely don't use it to push snow or with a snow thrower (which I'd planned on doing). Sigh... There's a company that sells upgrade kits for this mower with a significantly better trans that doubles the torque, is rebuildable, and it's easy to dump and fill the fluid for routine maintenance without removing it. I'm likely to take that route rather than have JD put another faulty transmission in. Unfortunately, the cost for that upgrade is about what I paid for the mower. Before you buy one of these, do a google search on the KT66 transmission upgrade available. You'll see stories (like mine) of folks who had their "tufftorq" K40 transmission fail on them very early and with light usage. One last nit...the tires have relatively poor traction. Lug tires (assuming that doesn't blow up the trans even faster) would be a very good addition. It struggles on wet grass and easily gets stuck in loose leaves. Love the mower, in general, but I wouldn't recommend it because of the very weak transmission.
