Friends,
I am a TYM and LS dealer in Oklahoma City. Indeed the R3039's are no more. I just received an email today (3/26/14) that there are no more of these units at the warehouse. They are replaced by the XR3037 tier 4 model. Basically the R and U models have been replaced by the XR and XU models, X is simply LS's designation for tier 4. On the XR models the horse power ratings have dropped slightly and on the XU models horse power has gone up considerable. Tier 3 U models included a 47 and 55hp. The tier 4 XU models are 55 and 65hp. For the rest of 2014 there may be a few tier 3 tractor around at dealers are thought the country but I would imagine that by June they will all be gone. Different manufactures have taken different strategies with regards to their introduction of tier 4 units. LS has opted to introduce their fastest selling units first in tier 4. This is because manufacturers are allowed to continue to import tier 3 models based off a percentage of tier 4 imports (I do not know the percentage). LS wanted to continue to offer the economy G series and the premium P series as tier 3 as long as possible. Do no quote me on this but I believe we will be able to sell some tier 3 models into 2015 but I believe that by 2016 all tractors above 25hp will be tier 4.
We have sold about a dozen tier 4 units since they have been introduced. The new tier 4 engines LS uses are actually stronger and more durable engines than their tier 3 cousins. The new tier 4 units are more fuel efficient, quieter, and have a much better oiling system. This should lead to a longer life expectancy for these engines. From looking at the retail pricing aspect of tier 4 you can expect to spend about $1000 to $2000 more on current tier 4 models over the tier 3 model. I have not seen pricing for the larger tractors, P series as of yet.
Hope this info helps,
