How did we handle the failure of a John Deere harvester?"},"content":{"rendered":"\n

Work was exceptionally busy in the summer. In July, we received an order for boring a hole<\/a><\/strong> at the coupling point of a John Deere harvester in the Czech Republic, just over the German border. Initially, we entrusted the task to our partner – a customer who six months earlier had bought an Italian mobile boring machine<\/a><\/strong>. Unfortunately, despite starting work on site, the partner unexpectedly resigned and returned to Krakow, leaving the client in a difficult situation. <\/p>\n\n

The customer was in a panic – the machine had to go back to work on Sunday. We made an immediate decision: we go to the Czech Republic and do the job ourselves. <\/p>\n\n

\n\n

Working in the forest – additional challenges<\/h2>\n\n

We arrived at the site of the accident in the evening, and thanks to the hospitality of the client, we had an overnight stay on site. As early as 7:00 a.m. on Saturday morning we started work. The situation was complicated by the fact that the harvester was located in the forest. This meant that we had to work with a gasoline genset, so unstable voltage and the risk of power shortages. <\/p>\n\n

Fortunately, we had with us the BORWELD SMART 40-1.0<\/strong> – a compact boring machine that is only 314 mm long (the size of an A4 sheet of paper) and weighs less than 14 kg. As a result, it can be installed even in hard-to-reach places, such as just holes in machine joints<\/strong>. <\/p>\n\n

\n\n

Step-by-step repair process<\/h2>\n\n

After preparing the site and digging a pit for the harvester, we mounted the machine and got to work:<\/p>\n\n

    \n
  1. Boring the hole<\/strong> – first we enlarged the hole by a few millimeters.<\/li>\n\n\n\n
  2. Naping<\/strong> – we used a short surfacing shaft (0.5 m) from the BORWELD kit. Shafts of 2 m, 1.6 m, 1 m, 80 cm or 50 cm are also available in our service. All of them can be found in our online store<\/a><\/strong>. For surfacing we also used equipment available in the section of welding products<\/a><\/strong>. <\/li>\n\n\n\n
  3. Rasting and correcting<\/strong> – the first layers of the surfacing required manual correction, but the subsequent layers laid down perfectly.<\/li>\n\n\n\n
  4. Accurate machining<\/strong> – we gradually brought the hole to a dimension of 124.96 mm, so that the 125.1 mm diameter bushing could be seated with a proper fit.<\/li>\n\n\n\n
  5. Additional work<\/strong> – we also carried out plane rolling and then set bushings and bearings.<\/li>\n<\/ol>\n\n
    \n\n

    The end result<\/h2>\n\n

    After several hours of intensive work, the hole was restored with precision to hundredths of a millimeter<\/strong>, and the harvester was ready for work the very next day. The customer was satisfied, and we returned from the Czech Republic with satisfaction and a reward of 1,500 euros. <\/p>\n\n

    Such orders show that even in difficult conditions – in the woods, with limited access to energy and working time counted in hours – BORWELD’s mobile boring machines<\/strong> allow the work to be done quickly, accurately and without compromise.<\/p>\n\n
