Starting Problems
Model Year: 0

I read the postings of this tractor being hard to start or rather starting problems. They talked about not getting fuel due to no prime opr air ion the linen clogged fuel filter, solenoid on the injection pump, but the problem that happened to me was the cold weather ignition switch located on or by the thermostat. We unplugged it and thew tractor started. There was NO FUEL COMING through the injector pump prior to unplugging the cold weather switch. Also, it would blow 20 amp fuses in the fuse box.

Pros: Easy to fix.
Cons: Pain to have starting problems such as this.

JD 5420
Model Year: 2004

Have fully been satisfied with my tractor. Bought it used 4 years ago and had only 2 issues with it. One the fuel system being the strainer in the bottom of the tank and the other issue is one currently have is an electrical on with the ignition which has not been corrected.

Pros: Plenty of tractor for the work I have. A cab tractor is a must. Like a zero turn lawn mower if you ever have one you will never have any other.
Cons: Electrical and fuel system.

5420 John Deere
Great Tractor
Model Year: 2004

This tractor was purchased to take the place of a 7711 Zetor. I saw it listed on the internet, and being close enough, took a Saturday and went and tried it out before purchasing it. I bought a loader for it and am well pleased with it. It is strong, both in engine horse power, and hydraulics. I've had no trouble with it. It starts well in all weather. I like the under slung exhaust.

Pros: Strong, quiet with underslung exhaust.
Cons: Power steering pump seems lacking when carrying a load on the front end.
