Deutz Agroplus 67 Smoky Start up

[biochemist3773]

I have a 2008 Deutz Agroplus 67 with 250 hours on it. I just bought it from a dealer with warranty. I am concerned about a lot of smoke at start up that lasts for a few min. I am told by the dealer this is normal for these engines. It does not smoke much if any when warm just the first few min. after startup but its a lot! If there is an internal engine issue I want to get it taken care of soon. Does anyone have any feedback on this? Is a large amount of smoke normal? He did indicate that the tractor had been "turned up" whatever that means. Thanks for you help.
