Last Fall I bought a single Jungle Jim trimmer rack for my trailer. It attached and held the trimmer well. I liked the design. I thought the construction was a bit light and the welds were not very good, almost tack welds. This spring after a couple of months I saw the welds holding the rack to the base breaking. I brought it to a welder and he re-welded all around the racks, commented on the weak construction and said the new welds would hold. Great. Then just last week I noticed new cracks, now through the base that hold the rack to the trailer. With a few wiggles the entire base cracked and the rack came right off of the trailer. At least I wasn't on the highway going 60mph and my trimmer goes through someone's windshield! I contacted Jungle Jim with this information - they have a 2 year warranty and I only had this for 6 months. They said that because I had a weld put on the rack the warranty was void! This is no way to treat a customer in this business. I suggest steering clear of Jungle Jim.
