We’re back with something seriously special… the new John Deere F9 prototype, working hard at Martin Evans Group LTD. This machine has clocked a massive 2,500 hours, making it the highest-hour test unit in the world - and we’ve been given full access to see how it’s performing. Donkey chats to Paul, who has been running the F9 since day one, to find out what it’s really like testing a machine for John Deere. From the big upgrades over previous models, to how the harvester handles the workload that Martin Evans group puts it through. Paul gives us proper insight you won’t hear anywhere else.
