It's around time to start my  building.
So I will remake the 8859 tractor.
The plan is to keep the functions :

  • Working fake engine (I might add some cylinders, as the original one is a 2 cylinder one)
  • Working rear PTO, with gear clutch safety
  • Working Steering wheel
  • Small turning radius
  • Working attachement lift
  • Differents attachement, at least the one shown in the original model

For now, I've rebuilt the orginal chassis (I forgot how these old sets are made… So much parts in one step)

I've also started to make the remake chassis. For now, the white clutch gear doesn't fit in the assembly… I have to find a working setup, that stays compact.

The main problem is that the dark bluish grey gear can't be replaced with the white one, as the white one touches the differential.

And finale a side by side comparison, for now the wheelbase is slightly larger (1 stud on each side) I will have to modify this.
The wheels are exactly the same diameter, but they have a totally different pattern. I hope it will look good.

Looks good so far! If there is really trouble in the diff section, you can always use the old one, which should fit without any problems.

Also for the wheels: We need the new tractor wheels in 81.6 mm! :D

Yeah, of course… The problem is that If I use the "old" one, the PTO will go trough two multiplication. And that make it turn really fast. And the clutch gear has therefore no use.
So I'm still tinkering to find a proper solution.

I totally agree !

A lot of progress was made this last days :
640x640.JPG

The differential was swapped for an older one. This allow space for the clutch gear.

The steering system was added. It's direct drive, from the steering wheel to the pinion rack.
The two red 11L liftarms will be replaced by the same in blue. (For now they're in an other build, and they are way too expensive to buy more.)

The steering radius is almost as big as the original set. It's lower, mainly due to the wheels used. They are way larger, therefore, the pivot point is closer to the center of the tractor.
The steering has a little Ackerman effect.

That's all for now.
Next steps will be the engine, the seat and the rear.

Update time !
A lot has been done in the past few days.

Engine has been started :
640x640.JPG

I'm still thinking how to replicate the grey side of the engine. The fake engine is linked with a total ratio of 5:1 compared to the differential output. This makes the engine do a nice sound.

The attachement lifting mechanism has been linked to some levers and ratchet.

The ratchet is controlled by a rubber band.

The linkage mechanism won't likely change, but the gear connection to the lever might change, depending on the space that the seat will take.

And finale, a side by side comparison :
640x640.JPG

On the to-do list, there is still :

  • The attachements
  • The seat
  • The hood
  • The rear bed (I might make it movable, even thought it isn't a feature on the original one.)
  • The cab

That's all for now. The progress might become slower for the next three weeks, as I will have a lot of things to do.

  • 4 weeks later...

Here's time for some new progress.

I've added the hood, and replaced some of the parts for bleu ones, as my Bricklink order arrived.
I'm still wondering what color to use for the front lights… As nowadays, most of the sets have trans-clear parts for the lights…
In the spoiler, there is the version with the yellow tiles.

The seat isn't done yet. however, the lights holder are ready.

I have also remade one of the attachements. As you can see, it can be lowered. This is done using the lever next to the cabin, as in the original model.
The goal is to make all of the three original attachements.

That's all for now :)

I think I'm near the end of my project. (For once I will be able to finish in time :grin:)

I've remade the second attachment :
800x600.JPG
As in the original one, the thing that goes in the earth (I don't have any idea how they are called) can move a little bit.
The spring mechanism has been replaced with the rubber 2l parts :
800x600.JPG
The black pin avoids that the black parts turns around.

The two attachement side by side in the spoiler, as I've already shown the first one.

I've also made the rear bed :
800x600.JPG

And I've finally made the seat :
800x600.JPG
The seat was inspired by 42054 seat, it allows to place a 
mining on the seat. It might be possible to place a technic figure in there too.

And a side by side comparison : 
800x600.JPG

I'm thinking of maybe removing the side panels, as depending the angle, they can look strange…

That's all for today. This is also probably the last update post for this MOC.

Needs the Zetros tyres...

If I was a reviewer I would have done that, but I'm not :sarcasm:
More seriously, they probably wouldn't work, as with the current wheel, the wheel is close to the chassis, when the wheel are fully steered. (This is here to ensure a small steering radius)
If I want to use zeros tires, I would need a 1L large chassis… which is not that rigid.

Ah well, superb work regardless! :thumbup:

Thanks :)
