Instructions for a correct working of cutter bars installed on articulated arms.
Double blade cutting bars – Heavy version
For a correct working of cutter bars installed on articulated arms it is mandatory to respect the following rules:
- The articulated arm must carry the bar weight indicated in the brochure;
- The auxiliary plant oil capacity must respect what indicated in the brochure, for example “from 45 to 65 litres per minute”;
- VERY IMPORTANT: you must have a single-acting auxiliary plant;
- Mini excavators have a tap where it is possible to select the single-acting option (indicated with a hammer);
- To connect the bar you need to have two pipe lines: a first pipe for oil entrance, a second one for oil escape – fot his model the drainage line is not required;
- Do not use agricultural quick couplings, only use industrial flat face quick couplings;
- It is recommended to have an oil cooler;
- The maximum working pressure is between 120 and 140 Bars.
Valves to be used for a correct cutter bar working:
Since we do not know the various hydraulic systems that our customers have we would like to give you some detailed information about the choice of valves to be used to obtain cutter bar best performance:
- Shockproof maximum pressure valve + oscillating valve (standard equipment):
You must calibrate this valve if the hydraulic plant pressure is superior than 130 bars. Important: communicate and check the pressure indicated in the articulated arm manual.
