Hello. I am 43 years old and all my lofe we had zetors. My constant problem was the brakes. Does anyone converted from dry brakes to wet ones or disc? I've seen indian tractors being converted
 
I think its not possible without changing the complete gear box with differential gear box to one from a Zetor 3321 Super up to 7341 Super Turbo. The housing has some differences - you can not put the wet brakes in the housing from dry disc brakes or dry drum brakes.

But when you mean you have seen it - so post some video links and we can take a look at.
 
Interesting...

This looks like a Zetor licensed build (HMT), with many different solutions (just the 180° rotated cylinder heads). Who knows what else was different from the factory, and apparently, the tractor underwent extensive modifications. Respect for the work – but it won't be available as an original solution or conversion kit suitable for Zetor.

Furthermore, the question would be whether the tractor won't lose its registration after the conversion, since the braking system is a safety-relevant component.

Nevertheless – very interesting video from the guys from India.

Zetor 6211 and 7211 are equipped with dry disc brakes. . I m looking for these parts.
 
Does anyone converted from dry brakes to wet ones or disc?
... wet ones only has series 3321 Super up to Proxima and this are every time disc brakes. Zetor doesn't produce wet drum brakes.

And If you mean convert from dry drum brake to dry disc brakes ... forget it directly again, believe me. ;)

To convert from dry drum brakes (e.g., Zetor 5211) to dry disc brakes, you would need not only the internal components (drive shafts, automatic brakes, brake discs), but also the externally mounted parts (handbrake rods, wheel brake cylinders and their brackets, brake lines, etc.), but above all, the appropriate differential housing and the appropriate axle spacers between the differential housing and the portals.

That makes absolutely no sense, neither economically nor technically. Yes, dry disc brakes brake better than drum brakes, but automatic brakes tend to lock up at the slightest touch of the brake pedal when used infrequently and especially in high humidity. So, they also have their problems.

A conversion to wet disc brakes would be even more complex than the one just described.

If you really want to do that, get the entire rear of a Zetor 3321 Super to 7341 Super Turbo and convert it completely. And even then you still need new brake lines and the modified handbrake linkage.
