Recently been reviewing information on the Hydraulics upgrades and want mention or advertise for company, however I've given this some though but have some questions. Also there is another video showing the added value. I do understand that it was stated that Deere voids the warranty when this is installed. I do see that it is added draw on the power train and added R.P.M. is needed to make it function properly. I suppose I'm trying to see the value of this versus the upgraded tractor but it does appear useful. Has anyone had experience with these units and is there a forum of evaluations.
