I have 200 hours on my 5835R. The tractor has been reliable with the only exception being the transmission control module needed to be "reflashed" due to shifting real hard. The weight with loaded rears and front loader is 7000 lbs. Plenty of power. Loader rated for 3400 lbs lift at the pins. Adjustable shift sensitivity.
Negatives: The seat has no adjustment for the back support.
