Hello,
i hope i can get some help here, my tractor is EU model but im sure it is quite same as USA models. Sorry but English is not my native language, i know what i learned from movies
I recieved a brand new Kubota M4072. The tractor is 36F/36R speed model with electric clutch acutator on gear shifter and also electronic gear reduction (im not sure about correct English name, but when you press this button it alters gear ratio by 20%). There are 3 main speed ranges, creep (snail), working (turtle) and transport (rabbit). This control is pretty u predictable and hard to shift. Manytimes it jumps between its three available positions and you end with false neutral or gear grind most of the times. While in transport range the tractor upshifts okay, but impossible to downshift. If you try to downshift you cannot sellect any gear anymore. Until the tractor is fully stopped, you can then put in any gear and go away. If you try to hold the gear shifter pressed to any gear on downshift it Will eventually jump into that gear and grind.
Dealer has no idea, they asked Kubota and have gotten a response the syncromesh needs time to "wear im". Im not sold on this idea due to todays manufacturing technology and its precision. Also on creep or working range the gear shifts are smooth, precise and perfect. In transport range, the downshift is impossible.
What could be my problem?
