Update ,
Found out what I thought was a left rear e - brake noise on my 2400h, had my tractor at Daves Tractor in Red Bluff “ nor Cal” Ca for a warrenty issue , Jarred in the shop stood by my tractor while I ran it in reverse , he picked up the noise right off , he grinned and said Dan that noise is coming from your front drive shaft under the cover we’ll shoot some grease in it , which was a relief ,also my throttle was super tight as on some of the the 2400 series , he said both issues were quick fixes they would take care of them ,no charge . Can’t say enough about Daves Tractor and the whole crew from the when you walk in the front door all the way up to Dave , all willing to always sit and talk with you about any questions and concerns , I have read on tbn many times Dealer choice is as important as make of tractor you choose , I feel I made a wise choice ,Dan
