trzrtree - welcome to LMF! That was a great detailed review - thanks for posting. I just purchased the same tractor - it was "on sale" for $2800, which they claimed was ~$900 off regular price (of which I was skeptical). I was also looking at the JD X300 and Kubota, but in the end I couldn't justify the cost differential.
I have many of the same observations you have. First and foremost the ridiculous plastic deck pulleys. I posted a request on this forum for experience replacing with metal pulleys, but got no response. So if you do make the replacement please let us know how you did it.
I'm curious how you wired your headlamp switch. I may want to do the same. I don't mind the running lights, per se, but the units are not sealed, so if it rains I'd expect to have blown bulbs. Check out
this post from member CajunCub - he has an LXT1046, and replaced his bulbs with HIDs and sealed the units.
I have already had issues with my deck, and had to place a service call today for a repair. The Deck Gear (part number 917-04074) is used to level the deck side-to-side. I think it's an ingenious design, but the part is made of some kind of cheap metal alloy, and one of the teeth on mine sheared off. I got it temporarily fixed but they're coming out to my house to replace it. I have the 3-year full in-home warranty, but they couldn't make it out to perform the repair until
MAY 25th!! That's almost a
MONTH! Fortunately, they're sending the part to my house so I'll be able to replace it before they come for the service - I'll just have them check everything out and adjust if necessary.
The deck wash system works great. I didn't use it the first couple of times I mowed, and wish I had. After two runs I had caked junk under the deck that needed to be scraped off. Once it's clean though, the deck wash system will keep it clean.
Removing the deck is simple enough on paper, but in reality it's a bit of a hassle. The front stabilizer bar has a bend in it that makes it impossible to get in or out of it's slot without a hammer. The lynch pin that holds it in place is made of the same cheap alloy, and mine is already bent (and likely will shear off soon, so I'm looking for a better-quality replacement).
The steering, as you point out, is funky, due to the design. If you run full speed on pavement the front wheels will track and need constant steering to keep straight. In other words, you can't just let go of the wheel and expect it to go straight. I knew this going in though - like you say if you want full bearings you'll pay almost twice as much for such a tractor.
I had the same observation about the brush guard, but not the same tenacity to fight it out with the sales folks. I tried to order one but it is out of stock - you probably got the last one!
All in all though, I love the tractor. It handles my field like a dream, which I know for a fact most lawn tractors won't. Since I don't have any steep hills I actually like the high CG - sitting up high with the arm rests is very comfortable.
Keep us posted on your experiences/upgrades!
