Wrappers

funkey_monkey

Looking into getting a round bale wrapper. Know very little about them mechanically so looking for pointers on what to look for and avoid. McHales and Conor seem to be a popular choice - is there any special reason for that or are they all much of a muchness?

I take it that the 3 point linkage yokes are only used for static yard wrapping and not used in the field.

Is it a straight choice between the Conor and McHale. I've seen a few Taarups on DoneDeal but they seem very low slung compared to the Irish versions.

I never heard of any great problems with the mchales or conor's apart from welds cracking. I put about 40000 bales through 2 different bjs wrappers and the only thing that ever went was a roll pin in the middle of the table and a few shearbolts on the rollers. Both only take a few minutes to fix. The first mchale I would swear every weld on it had cracked at some stage but the second one had little braces welded into all the corners to prevent the fatigue and it worked wonders so if you are looking for a mchale try and get one with them on it, Makes the world of difference because you wont find its predecessor that hasnt been welded on a few different occasions. I wrapped about 200 bales with a conor one day and I didnt like it, the table seemed to high on it and bales tended to fly off easier, prone to cracking at every seem like the mchales too a contractor that had them told me a few years ago. Make sure the cut and tie works ok on them too. Its easy enough to pick out a good one from a bad one. One thats shot will look wrecked.

I have an ancient Kverneland 7510. Works great, needed some welding on the base for the first time a few years ago so I stripped it and rebuilt it. Probably would buy a McHale if buying again, if only because they are a clone of the Kverneland/Underhaug to begin with and there is a better selection of them about.

The tie and cut on our seems to be causing problems. When I raise the table to eject the bale, the arm which is meant to gather the plastic to be cut does not lower until the table is fully raised - which is too late. This means I have to balance the bale on the partially raised table whilst tension pulls the plastic down far enough for the ram to grab a sufficient amount of it to operate the cutter and also not release when turned around.

I've checked the hydraulics and the collecting arm is worked off the hydraulc supply as the table - normal t-joint in the pipe work. The only other thing is that the collecting arm is worked off a single acting ram with a return spring - which has been replaced.

Is it possible that the return string is too strong - the collecting arm only engages when the table is fully lifted - i.e. when its ram is getting the fully supply from the tractor. I've noticed that if I tip the table fully and engage the collecting arm that within a very short space of time the single acting ram will start returning to its closed position.

Is this an issue anyone on here is familiar with - or as I think is it that the previous owner has replaced the return spring with an item which is far too strong for its intended job?

Thanks.

The design concept is that the pressure required to actuate the gathering ram is far less than that of the ram lifting the table hence it gathers the plastic 1st.. my guess would be the spring.. if you know someone else who has the same wrapper disconnect the hose and pull down the arm manually and do the same with your own... a simple check..
