Hi there from Germany,
yesterday I was out in the forest and wanted to take home some firewood in a bucket with my B4200D, which made the left lifting arm snap in half at the hydraulic shaft arm.
I guess it was about 300 lbs wood + 100 lbs for the bucket, being 400 lbs in total. I wanted to check if it was too much and the tractor would lift in the front and went in the bucket myself (with some momentum), having a total weight of about 600 lbs. The tractor did not went up, however the left lifting arm went into two parts :/
This lifting arm seems being made of cast iron. I looked at the position where it broke and it seems to be rusty, thus I guess the lifting arm was already weakened by a fine crack, which was not visible to the eye. I took some photos of the broken arm, the other part still sticks to the shaft, rusted in place, held with a bold.
I have two questions:
1. Is 600 lbs a weight which should not be applied to this small machines and it was clear, this would happen? I guess I overloaded the machine about 50 to 100 lbs concerning the overall weight (including myself, the driver), however the weight on the axles was within the limits more or less. My machine has 210 hours on the clock now, looks very good (except a little bit rust here and there). Or was I just unlucky and this weight is ok? I am still new to the tractor business and I certainly do not drive very fast over rough terain, I am too scared.
2. How can I fix it? I already looked up some drawings in an online shop telling me my arm has the id #66621-36743 - is that the correct part?. I this part in a web shop for about 320 $. I guess welding it would be very difficult and has to be done by an expert for cast iron welding. My hydraulic shaft arm, where the arm would be connected to, also seems also to be rusty, however I guess I can just polish things up and put on a new the lifting arm. I also saw the whole set of shaft arm and lift arm as a kit, but I guess I would not need to replace everything. Any recommendations?
Cheers,
Egger
