Drum Mower Setup - Samasz 1.65 Z010

Our old Fahr mowers used to sit like that. Very similar design.
The Unifarm mower we have now has a different backbone design to those, and it lifts up straight instead of flopping. I have NO idea how, just that it does!

I'd be tempted to redrill the top backbone bar at the headstock end and shorten by 20mm, see what it does. If it doesn't work, then you haven't lost anything. And all it should mean is that your linkage will sit lower to get the float pin in the middle of the slot when on the ground.

So to give an update. The mechanics from where is was purchased turned up again to have a look as they couldn't understand what the issue was from he telephone conversations we had with them.

After many alterations it was decided that it didn't fit correctly. It needed a lower hole in the MF390 for the top link to sit correctly.

The did say the some modification could be made and it might fit.

It was purchased to go on the JD3050 which was explained to them at the time and they said that it would fit an work perfectly, which is didn't. Making modifications to get it to fit on a different tractor isn't something we wanted to do, so we came to an agreement that the mower wasn't suitable and they would take it back and refund us the purchase price.

Thanks for all of your help.

Do you not mean a higher hole? Looking at your picture, it looks like the top link is already in a lower hole... you want it to pick up and raise level, not tilt so far forward?

Always good to get the update/happy conclusion.

Rather than moving the top link to a different hole, could he not get a top link with a different length?
Surely the top link length is controlled by the angle of the mower when in working position. Any alteration to the length when raised will affect the working position.

Would have the same effect

Not if the top link increased length more than using a different hole does.

Several threads discussing using different sized top links here:

It's been great reading all these comments, but it also demonstrates how little we know about everyday machines we use.

It's a two drum mower, basically never changed since the wizzler, other than 4 drums to 2.

The problem was, the mower did not lift parallel to the ground, this is because it is a low tech, low cost two drum mower, no frills, just mows.

To accommodate changes in ground contour, the flotation slot allows for ground that is falling away as well as raining inwards. Good benefit for undulating land.

No amount of piddling around with the linkage can change that once the mower is set correctly.

However, if you want it to lift parallel to the ground, you can do two things.

Screw up the r/h arm to it's highest position, and l/h arm to it's lowest, this should take out the movement in the flotation slot. OR block off the end of the flotation slot.

Neither is satisfactory, the head-stock of the mower will look daft at an angle, and you will have no fall away flotation.

Playing around with the angle of the top-link will alter the angle the mower raises and falls (arc), but will not change the fact it is not parallel to the ground.

As it is, it's irrelevant as the mower has gone back.

Not aimed at you personally just trying to explain linkage geometry.
A different length as said will not keep the mower level in work but different distances between top link and lower link affects the geometry. Consider a bale spike, the spike needs to be level two feet off the ground to go into the bale but as it’s lifted it needs to angle towards the tractor to keep the tip of spike higher than the base. To achieve this the distance between top link hole and lower link holes on spike needs to be longer than the same two mounting points on the tractor. For a machine such as a topper with a centre mounted gearbox with a PTO shaft you need the topper to lift just off level to stop the topper frame fouling the pto shaft and limiting the heigh you can lift it so again distance on machine greater than on tractor. If you wanted to lift an implement dead level then both measurements need to be as close as possible. Another example would be a fertilizer spinner that needs to be level ar work.

Now the drawback is that the closer the two dimensions are on the tractor the more strain it puts on the tractor and therefore it’s lift capacity is reduced as not only is it trying to lift the implement its trying to hoist the rear if machine up in the air quicker. For example you would never have a plough on the bottom top link hole of tractor.

Our JD disc mower lifts on the linkage and doesn't clear the swathe high enoughuntil we screw the RHS arm up as far as it will go. The headstock sits slightly lower to get the proper float position in work as a result.
You can easily do the same on a drum mower. The PTO and linkage doesn't really care if the headstock is slightly twisted... just make sure it's in the right place to float in the slot. It doesn't solve the problem of not lifting out parallel, though...

I found this quite confusing. We have an old Zetor 185 mower which looks just like a red Samasz. Been on 3 different tractors and only some top link adjustment needed to level it. Set it up on concrete yard and away you go. Must be something funny about the geometry of the Samasz headstock.

Hello
I have experienced the same problem with my Samasz z010 165. I used it on our old Volvo BM430 and Volvo Bm2200 with no problems. I sold the BM2200 and bought a Zetor Proxima 65 4wd. On the Zetor the mower touched the right rear wheel. I went back to the dealer where they decreased the rear tread so the distance between the rear wheels is smaller. It seems to have solved the problem. I have not cut any hay yet but will try it as soon as the weather is more stable. I live in the middle of Sweden.
