Back in 2010 I ended up with Kubota because the Deere dealers wouldn't give me the time of day. When I walked in and asked about 30hp to 60hp tractors the salesman pointed to a spot in the yard where some were and then went back to puttering on what he was doing. At first I figured he was in the middle of something and would go out in a couple minutes when he was at a place he could stop so I went out to look at them. After about a half hour and nobody came out to answer questions I went back in. After being directed to go to the Deere website to find answers I left. As I was leaving a farmer walked in and was treated like an old friend. Seams that $30k for a tractor wasn't enough to bother with.
Kioti at the time was just as bad as they knew nothing of their products and the brand seamed to jump from dealer to dealer, it's much better now. This spring I bought a Deere X500 from Deere dealer. They didn't deal with large equipment and were totally the opposite of my first experience. They gladly answered questions over the phone and then while there let me try a couple different models while listening to what my uses were for it. Since I had already done my homework he quickly skipped the mowers that wouldn't fit my needs so he could focus on the differences between models that would. He knew I was there to look a a year old used X500 but wanted to make sure I understood the differences so I didn't pass on something that I would want. It wasn't like he was trying to sell me something more than I wanted or push a new mower over a used one. The difference was I was now a customer looking at higher end equipment where as before I was just someone looking at little tractors at a dealer who made their money selling large equipment to farmers.
It sucks that you're having problems. A coworker had a problem with his Kubota. It was self induced. He got hay into the fuel tank and had engine issues. The dealer was slow to work on his tractor, had it over a month before looking at it and then gave him the "we couldn't find anything wrong with it line". The second time he brought it back they finally fixed it but it took a good 3 weeks (most of which was just sitting there). That was almost 2 months in the middle of summer for a tractor that was bought so he could offer a brush hogging service. The dealer didn't seam to care one bit. This was the summer before I bought my Kubota. Needless to say I didn't even bother with them.
Every company makes a dud now and then. Sometimes it's just one tractor, sometimes it's a particular model. It happens. The companies count on the dealers to make it right and deal with the customers. It's the same with car companies. It's amazing just how badly a dealer can make a bad situation a lot worse. In a company's eyes they want the customer to tell the dealer their problems and dislikes and for the dealers to pass along the issues the dealers think are real. All to often things fall apart. It helps if you can find a dealer that specializes, at east in part, in selling what you are buying. Even then there's no guarantee that your dealer will make things right in a timely fashion.
