I cant speak to TYM as there arent any dealers near me. I have seen a lot of them in other countries ie Peru, Nigeria, Mexico where the bigger Ag tractors are popular.
Dealers come and go at will it seems. One long time NH dealer shut down and now sells ATV's, who would have thought that would happen. Every ones says get a good dealer. My take is that friendly dealers while being good to negotiate with and whatever doesnt guarantee they will be selling your brand next year so get a good tractor to begin with.
I like my LS even without having a nearby dealer as mine is a short 60 miles away and what with the 3 broken parts in over 2 years. Only parts I have needed were filters which were drop shipped to me with exception fuel tank which I had to go get and seat suspension and drawbar bracket which I took the tractor in for repair and full checkout as 2 year bumper to bumper warranty was expiring. Everything was ok and new parts fitted . So everything that I broke has been fixed free of charge (seat suspension, drawbar attachment bracket, fuel tank). It only took about 3 days to get the seat and DB bracket last month although we did fix the seat bracket by welding up the pin that broke. It took 6 weeks to get the new fuel tank in as it had to come from Korea. This happened in spring of 2011 right after they started selling them and about 6 months after I bought it. Even though the fuel tank breaking was partially my fault for running over trees and saplings, LS redesigned the bracket holding the tank and skid plate, sent me a new tank complete with cap and fuel sending unit intact. I still have the new one in my shop waiting on my JBWELD repair on the cracks to fail which most contributors on TBN thought would happen in less than 6 months. Its been about 18 months and counting for the home repair with epoxy.
I can say that LS is very pro-active in redesigning a failed part when it appears to be a problem. The fuel tank attachment was redesigned to protect the tank from fractures, the seat suspension was redesigned to be stronger even though the problem was a faulty inadequate weld and the drawbar was also redesigned to be a bit stronger. They dont seem to just set on a problem like I have seen complaints on TBN from other brands.
The power on the P7010 is phenomenol. Yesterday I was picking up some brush using the FEL and once when repositioning the FEL so it was closer to brush while running at 1000 rpm. I heard a little ping from the disc blade but thought it had just hung a vine or something and next thing I know a 10" diameter x 50 foot pine tree comes crashing down beside my tractor. I had hit it with the outside blade on my 8 foot disc as I turned and just pulled it right over without a groan from the tractor. I was very lucky on that one that it fell parallel to the tractor and not on top of it and also missed my brother in law who was loading brush on the other side of the tractor.
I am pretty rough on equipment but the LS has stood the test for ruggedness and reliability. The engine oil at 50 hour change was clear as new oil which was surprising for a diesel. Everything is fairly easy to service although I did have to go buy a 25mm hex key wrench to change the engine oil (the drain plug required that size to remove the two plugs.
