For all of you that have an X300-X500 riding lawn mowers, I don't have to tell you how reliable they are. I just keep clean oil in the engine, sharpen the blades frequently, and grease all of the fittings. BUT, some of you may have noticed that the steering gear wears out on the side associated with left turns. This makes sense, because the grass discharge is on the right side and most people mow counter-clockwise (like NASCAR drivers) so that the grass always discharges onto the previously cut grass. Alas, this behavior causes the steering gear to wear out on one side. It would be a good thing to make this gear out of a thicker piece of metal or, perhaps, make the side associated with left turns a little thicker. That would be a small design change to enhance the reliability. These gears cost about $60.

I keep my sector gear and pinion clean and lube with a little white lithium grease each time I service the tractor. I also have the mulch kit installed so I can trim on the left or right side. :)

The steering system is pretty robust and we don't see very many issues with parts wear. Had 3 in this month, 2 bent front axles and 1 broken. But the sector gear and steering shafts were fine.
If yur gonna lube I would consider a spray on dry type stuff.
Also keep the steering spindles lubed well. The lesser the steering force the better. I lube mine every other use. Just a couple pumps along with blade spindles.

I don't recall every putting lube on the steering gear, but now that this has worn so severely, I may start spraying it with moly-disulfide. This is one of those things that I normally wouldn't have though about servicing. I do a pretty good job of servicing all of the grease fittings.

How do you get to the steering spindle. I have a x580.

Sounds like it would be a good idea to add some road courses to your mowing schedule, so you can turn left and right, just watch out for the "Bus Stop" on the road courses as it tends to cause some issues at high speeds......:laugh::lol:


How many hours are on your machine?

This guy talks about the steering in his video starting at about the 17 minute mark.
2016 John Deere X570 - 250-Hour Update (Long Overdue) - YouTube
I always get a kick out of these guys who get all hopped up over the robustness of their "garden tractor". In this video the guy points out the heavy duty 5-bolt hub on the rear wheels and goes on about how it's more sturdy than other tractors with a typical "axle key and snap ring". Little does he know that the "heavy duty" 5-bolt hub is secured to the axle with a simple key and snap ring. :)

I doubt he even realizes that the X500 uses the same chassis as the X300.

watch some of his plow day videos. I think that kid had a better understanding of what is and what isn't a garden tractor than the majority of the posters here.
