I personally know of a large number of instances where "name brand" dealers did not stock parts that were needed, and the parts had to be ordered, resulting in significant delays.
Here is a thread on the Kubota forum where Kubota owners are complaining about parts availability problems:

This from the John Deere forum:

I must say though, I'm not impressed with JD part supply system. I have had the 2305 a my house for 2 weeks and made a deal on this thing over a week ago. I am still waiting for the cruis control and mulch kit for my MMC to arrive so he can get the tractor back and we can finalize our deal. Not that I need a mowing deck now, but I am shocked at how long it takes to get in a couple of parts and finalize this deal.

I have a 1700, have had it for two years. Nice tractor. I mow about six acres with it, using a Woods five-foot mower. Level land.
Parts can be a task to find. Some things can be found on ebay- like light bulbs. Be preapred to be a tinkerer sometimes with it. I had some electrical problems and had to rewire some circuits. I used I&T shop manual for reference.
So much for the myth that you can go to the dealer and get all the parts you need, and have the equipment running without waiting on parts.
I guess these folks wouldn't be having problems getting parts for their Kubotas, New Hollands and Deeres had they not bought off brand products, that way they would have had that great dealer network service everyone keeps talking about being a necessity.
Here I am stuck with a Mahindra where most parts can be overnighted, if they are not in stock. I am sure there are some parts, just as there are with NH, JD and Kubota, where I might have to wait for them.
Realistically, dealer network doesn't mean nearly as much in the age of the internet as it meant twenty years ago. If I didn't have a Mahindra dealer withing 500 miles of me there are a number of dealers on this forum that would be willing to ship me the parts overnight.
