Checked with TuffTorque. A new K46 costs just under $500 + shipping, replacement is 4 bolts and 3 clips. Or rebuild parts around $200 and fairly easy for a do it yourselfer. If mine lasts 300 hours that's 10 years! So I bought the X300 instead of a X320. Never considered the LA100 series as I wanted a tractor that was well built and that could be repaired year after year. Again buy what you need, I'm a light user.
I don't know why they call the K46 disposable as they sell rebuild kits and parts for them (not through John Deere though).
:thumbsup:John Deere D100 Vs X300 Lawn Tractors
On the showroom floor there does not appear to be a whole lot different between the John Deere D100 Series model riding mowers and the X300 Select Series models. So why does the X300 Series have twice the warranty?
Heavier and More Durable Frame
The X300 Select Series frame is a solid one piece frame weighing in at nearly 100 lbs and the D100 Series frame is a two piece welded frame weight in at a little over 50 lbs.
This X300 Select Series frame is also thicker to make it more rigid to hold up for years of use and the added weight improves traction and better attachment performance.
Larger Transmission For Increased Productivity
The X300 Select Series transmission provides 165 lb-ft of torque and the D100 series models product 126 lb-ft of torque which is about 25% increase.
This increase in torque allows the X300 lawn tractor to climb hills better, tow more weight, and push more snow. The X304 model also features all wheel steering for tighter turning in and around obstacles for faster mower times.
Engineered For Comfort and Convenience
The X300 Select Series models feature a higher back seats with more suspension travel, foot operated deck lift rather than hand lift, standard cruise control and electric PTO engagement.
These features keep the operator more comfortable during their time mowing and reducing fatigue from lifting deck and other front attachments by hand.
Twice the Warranty
The X300 Select Series lawn tractors also come with a 4 year / 300 hour warranty vs the 2 year / 120 hour warranty on D100 Series mowers.
This increased warranty shows John Deere has more confidence in their Select Series line-up and with quality and performance upgrades they are sure to last the test of time!
I got a well-used X300 along with the house and 2.5 acres in '09. Never have a problem, other than battery, and didn't know I was supposed to worry about it, until this thread. Now the tranny will go out for sure.
It's been a good machine but the mower bogged down when the pasture got chest high in spring, so I bought the Kubota to power through it. I use the X300 around the house, and the B2320 for everything else. I actually also used the X300 to drag some weighted chain link around for leveling and overseeding and sometimes pull a little garden wagon around.
I don't know how long the former owner had it, but I am at 3.5 years. I wonder how much longer my junk transmission has left?
