round baler for tractor

When you hear “roll baler for a tractor?”, many people immediately imagine a simple unit that simply reels in hay. But in practice, the difference between what “seems to work?” and the fact that it works efficiently and without breakdowns in the midst of preparation is enormous. A common mistake is to chase cheapness or, conversely, redundant functions, without taking into account the specifics of your land, the type of tractor and, critically, the quality of mass preparation.

Not just a “shaft”: design and basic principles of operation

The heart of any round baler is the bale chamber. There is already a division into models with a constant and variable camera. The first, like many old Claas or New Holland, form the bale with rigid shafts. The density is initially specified by the geometry. The second - with a belt or chain chamber - start with a small diameter and increase the pressure as the roll grows. These are, for example, many models from Kuhn.

For our region, with often damp second-cut hay, a variable chamber turned out to be preferable. You can compress the damper mass more strongly, achieving better preservation. But there is also a nuance here: if the belts are loose or the tension is set incorrectly, the roll will be loose and uneven. I checked it on my old “Polesie” - I suffered every autumn.

The drive is also history. You need to clearly correlate the power take-off (PTO) of your tractor with the requirements of the baler. I once rented a powerful unit for the MTZ-82, and it had a PTO of 540 rpm, and the baler required 1000. I had to improvise with the pulleys, in the end we lost a day and almost burned the belts. Now I always look at the registration certificate first.

Key components to look at when choosing and working

Pickerwith adjustable height - a must have. If the teeth hit the ground on uneven surfaces, they bend and break, plus dirt accumulates. It’s good to have a support shoe that “licks” relief. Some budget models do not have this, hence the frequent breakdowns and loss of hay on bumps.

Needle or rake reel? The rake is less capricious, winds less, but can crush delicate masses, for example, alfalfa. Needle-type is more gentle, but requires care and cleaning. For mixed herbs, I tend to use needle herbs, although I have to spend a couple of hours cleaning after work.

Strapping system. There is progress here. The old mechanical twine spool units were a nightmare to break. Modern electronically controlled systems, as on balers fromHulunbuir Machinery Manufacturing Company ?Jiujia?that are presented oncn-fascar.ru, much more reliable. It is important not only to lay the twine evenly, but also to ensure sufficient tension. A weak knot and the roll will fall apart during loading or transportation.

From practice: setup and typical problems in the field

The most common mistake made by beginners is incorrect initial pressure setting. Set it too high for dry hay - the bale does not form, the mass slips. Too low for wet and you will get a large but loose roll that rots quickly. We have to select it empirically; often at the beginning of the season we make several test rolls at different settings.

Humidity is the main enemy. Pressing mass with a moisture content above 18-20% is a risk. Not only in the quality of the feed, but also in the technology. Increased load on belts, bearings, risk of spontaneous combustion. You have to wait for the ?window? in the weather, which is not always possible. Some colleagues use preservatives, but this is a separate issue and additional costs.

Broken twine or net. If a break occurs in the middle of the cycle, often the entire half-finished roll goes to waste. Modern systems have control sensors, but they are not a panacea. I always carry with me a supply of coils and tools for quick replacement. By the way, the quality of the twine itself plays an important role. Cheap polypropylene can be very capricious.

About the choice of manufacturer and the adequacy of equipment to the conditions

The market is flooded with offers. European brands (Claas, John Deere, Kuhn) are the standard of reliability, but the price and spare parts. Domestic and Belarusian ones are often easier to repair, but there are questions regarding the quality of metal and assembly. Lately I’ve been looking at equipment from Chinese manufacturers who are seriously investing in R&D for our conditions.

Here, for example,Hulunbuir company ?Jiujia?. If you go to their websitecn-fascar.ru, it is clear that these are not just collectors, butmodern integrated smart manufacturing enterprise. They rely on adaptation to different regions. I looked at their models of balers - the hitch and pick-up units are noticeably strengthened, and there are more powerful gearboxes. Apparently, they took into account our difficult soil and large volumes. For a large livestock farm where continuity is important, this approach may be justified.

But it is important to understand: even the most advanced technology will not solve the problem of a poorly prepared field. An uneven windrow, different densities of the mown mass - all this places additional stress on the unit. A perfect bale starts with the mower and windrower.

Thoughts aside: maintenance and modernization

Routine maintenance - lubrication of all bearing units, checking belt and chain tension, sharpening or replacing pick-up teeth. I do this not according to a thumbnail schedule, but according to actual operating time. After 500-700 rolls, I definitely shake everything up. It’s better to spend a day in the garage than to then stand in a field with a broken belt.

Is it possible to upgrade an old baler? Partially. I installed an additional hydraulic cylinder on my own for a smoother opening of the rear wall - it became more convenient. I tried to install a homemade chamber fill sensor - it turned out crooked, I refused. Conclusion: it is almost impossible to radically improve productivity or roll quality with an upgrade. The structure was laid initially.

In the end, the choiceround baler for tractoris always a search for balance. A balance between price and reliability, between manufacturability and maintainability, between the desire to get the perfect roll and the real conditions of your farm. There is no universal answer. There is a careful calculation of your capacities, analysis of soils and crops, and, of course, a willingness not just to buy hardware, but to delve into its configuration and daily operation. This is what turns the unit from a costly item into a real assistant.
