I'm going to try and make this as short as possible, I'm so frustrated. About 5 years ago I bought a brand new 4520, i only had about 70 hrs on it and long story short it had an electrical problem to where it would sit for 2 or 3 weeks and then not start up. I didn't have my tractor for months throughout the year. It was In the shop multiple times and they could not figure out the problem. It also had several mechanical issues.
After a long hard fight with corporate they told me they would buy the tractor back but I would have trade up to a 4066r so for about 7000 dollars more that's what I did. I noticed from the start the hydraulics seemed very weak on the tractor. I told John deere about it but they said they were up to specs. Last fall there was a recall on engine. I took them till spring to fix it. We also noticed a rear axle leak , tractor was still under warranty. I told them while in the shop to check the hydraulics and the loader problem as mentioned on this forum. The axle leak was back ordered for months and again my tractor sat in the shop for 6 weeks. They told me they would return my tractor and to run it with the rear axle leak. Finally the part came in , it took 2 more weeks in the shop they finally fixed my tractor and said the hydraulics were up to specs by a field rep.
I got the tractor back and just bought a new drill. My tractor should have picked it up no problem, it didn't budge it an inch off the ground. My buddies kubota mx5100 lifted it with no problem, it has less lifting capacity the my jd by a few hundred lbs. So I call them again. While on the phone with a different dealer. He mentioned they now have a "product improvment" warning for the loader the I mentioned. I gave them the I told you so and my tractor is now back in the shop. They supposedly fixed the loader problem, but are now waiting on back ordered parts for the new improvment problem with the pistons and valves for the 3pt hitch. I told them I'm done with this tractor. It just turned 2 years old and has 170hrs on it. I'm losing money in my sweet corn and pumpkins etc. They may give me a deal if I trade up to a 5090m, but I'm so scared to get another deere at this point. I have a b series kubota with zero issues..I'm not a picky or crazy consumer... .does this seem fair to be jerk Ed around like this??? Are the bigger tractors better quality? This is too much time with large tractor payments and no tractor to use.
