Avant 528 with clamshell bucket
This is the one of few upgrades which I have made so far for my Avant 528 but it is the first one which I decided to share with you. In general Avant is good tool but at the same time manufacturer can't guess any customer needs upfront, and this is exactly the case. I have quite a long ditch which time by time requires to be cleaned. As mainly it has sludge there then it is quite impossible to do it with spade therefore I decided to make additional tool for my Avant in order to deal with that- and here is result. Mechanical part was an easy one- bought 60L clamshell bucket, welded main frame for that (1500mm long 80X80 steel tube, with its wall thickness of 8mm). The problems started with hydraulic- all Avants (at least 500 series) have just one pair of hydraulic outlet which doesn't allow to operate bucket and it's rotor at the same time therefore I did its upgrade to two pairs of outlets using solenoid valves. The second thing which isn't available for 500 series Avant is option to control its auxiliary outlets with joystick (despite such option is available for 600 series and above)- therefore I bought joystick itself (called joystick 8 functions)from my Avant dealer and using appropriate relays created control unit for that- was quite a difficult task but result is excellent and I'm really proud of that.
