John Deere 850 Tractor User Reviews

John Deere 850 tractor is easy to drive at various speeds and gears on hills as well as flat surfaces and also in rough terrain. 

This model has also received praise for its excellent set of tires including the rear tires reaching upwards.

A different reviewer reports that, despite being capable of performing nearly all tasks, however, it was light, so using this high power could cause a loss of grip. 

Even though it comes with pneumatic tires, there are some who have reported losing grip before.
