Hi
As I wrote in post #18 in the following thread recently, I have been blessed with good luck for most of the 13 years that I have had my BCS 740:
Zanon ZRF 1000 drum mower
I have only had minor issues like a flat tire or a broken starter rope - that is until October 30th, when the above mentioned damage happened to my Zanon drum mower
Only 5 days later bad luck struck again, this time hitting the tractor itself. At the end of a job with the drum mower, the handlebars felt „spongy“, especially in the vertical direction. As I had parked the tractor on the trailer, and removed the blue plastic bit that covers the handlebar assembly, I saw the following:
The left photo shows the left hand side of the handlebar assembly where it swivels around the vertical post. The right photo shows the right hand side.
I am of course aware that this is a part of the handlebar assembly that has to cope with quite a lot of stress, especially when working with heavy implements like the flail mower or the drum mower. Still, I was a bit surprised to see this.
This topic was mentioned more than 4 years ago in the „Berta flail mower“ thread, where our member „ppea“ expressed his concerns regarding the risk of braking the handlebars when working with heavy implements. I have had similar concerns over the years, especially with the flail mower and the drum mower, as they are quite heavy, weighing 92 kg/203 lbs and 80 kg/176 lbs respectively. Pressing hard on the handlebars to get these heavy implements off the ground, of course puts a lot of stress on the lower part of the handlebar assembly where it meets the vertical post. Up till now I thought it was up to the job, but it wasn’t anymore
As with the drum mower recently, my neighbor had a look, and with his lifelong experience working in a machine shop, he had a to me surprising comment concerning the welding on the right hand side: „It’s not the handlebar assembly that has broken, it’s the welding!“ I’m no expert on weldings, but to me there is a clear difference between the two sides of the handlebars. On the left hand side the welding seems to be intact, whereas on the right hand side, it seems to me that the welding has given in, and the assembly itself is still intact. This can perhaps be seen even better on this photo taken from above:
For a professional welder like my neighbor it was no big deal to weld both sides again, and in the future I will need to keep an eye on these parts more often
Best regards
Jens
