Maintaining a John Deere 5620 from the 5020/5020N series? This page has more than 400 matching parts, including lighting, electrics and trailer couplings.
More than 400 John Deere 5620 parts are gathered on this page, covering the jobs that come up again and again on a working tractor of this size. Brands include GRANIT, HELLA, FEBI, MAHLE and Wabco.
Much of the routine work on a 5620 happens around the engine. There are O-rings, for example for the oil pump, gaskets such as the one for the regulator housing, and seals for door hinges and pull handles in the cab. For the belt drive you can choose single multi-rib belts or a complete belt kit, with or without air conditioning. Plugs, bushes and sensors are also available.
Belt choice is where many people go wrong on this tractor. A machine with an air conditioning compressor runs its belt over an extra pulley, so the belt is longer than on a tractor without one. Look under the bonnet before ordering. When you swap the belt, take a photo of the routing first and spin the tensioner pulley by hand. If it feels rough or has play, replace it at the same time.
On the electrical side there is a starter motor, alternators and LED work lights as well as work lamps with a spotlight beam. Headlights for dipped and main beam are on offer too. For towing there are drawbars, including an automatic type, plus connector heads for the air brake line. Internal plates for the clutch complete the picture.
The type plate confirms that your tractor is a 5620 from the John Deere 5020 series. For the part itself, the reference number is the best guide. John Deere stamps it into many castings and prints it on gaskets, so copy the number from the old part and compare it with the details shown with the product. With bushes and clutch plates that check matters most, since different versions look alike from the outside.
One tip for the brake couplings: red is the supply line and yellow is the control line. When you replace one connector head, check the rubber seal in its counterpart as well. A cracked seal leaks air and takes only a few minutes to change.
Parts for other models from the same maker are listed under John Deere parts, with one page per tractor.
If the number on a starter motor has worn off, count the teeth on the pinion and check the direction of rotation and the mounting. Those features are given with each product, so you can match them to the unit you take off.
