Why Can Tractors Pull So Much? (Explained for Beginners)
You might be wondering, why do tractors pull so much weight compared to trucks or cars?
The answer is that tractor pulling is based on torque and horsepower, meaning that their engine should be modified to offer as much power as possible.
Tractors are developed to offer gobs of torque at low revolutions per minute (RPM). Therefore, they can multiply torque thanks to having a lower gearing than trucks and cars.
This gives them a tremendous mechanical advantage that allows them to pull heavy loads slowly.
Here, we focus on the tractor’s pulling capacity.
How Much Weight Can Tractors Pull?
The total pulling capacity of tractors isn’t constant since different builds and models of tractors have distinct towing capacities.
Additionally, different factors contribute to the variation in the pulling capacity of each model.
Tractors are designed to operate at a relatively low speed and very high torque. This allows them to pull and haul heavy objects.
Even though the pulling capacity of tractors isn’t specific, we can still have an average or estimate for the pulling capacity of each tractor.
For instance, smaller tractors are designed with a low pulling capacity of about 2,300-2,500 lbs.
High-end tractors developed for heavy towing can pull up to 9,000 lbs. However, 3,500-4,000 lbs are the common range for most tractors.
As you can see, the pulling capacity varies from one tractor to another. Therefore, consider the towing specifications of every tractor on your shortlist before buying.
However, we recommend buying a tractor with a high pulling capacity for maximum efficiency.
Determining The tractor’s Pulling Capacity
The best approach to determine the tractor’s pulling capacity is to check the user’s manual. It usually contains the maximum pulling capacity of your model.
The towing capacity mentioned in the manual is the total weight of all the things the tractor pulls on level ground, including added gear or special modifications to the tractor.
In some instances, especially for old tractors, it’s difficult to find such specifications in the user manual. In such a case, you can estimate the tractor’s towing capacity by multiplying its overall weight by ½.
This gives a maximum suitable weight that shouldn’t be exceeded while pulling objects. For you to apply this rule of thumb in a situation where you can’t find the tractor’s weight on the user manual or chassis, weigh the tractor at any truck stop scale.
Factors Affecting A Tractor’s Pulling Capacity
Several aspects also affect the tractor’s ability to pull objects apart from the towing capacity. The factors include:
- The property layout: The tractor’s standard weight capacity is determined for even solid ground. Pulling in a mushy soli or uphill can take much of the tractor’s torque.
- The tractor’s extra weight involves any front or rear attachments on the tractor, including front-end loaders.
- The towed object’s evenness: It’s very difficult to pull an object whose weight is unevenly distributed.
Can Pulling Heavy Objects Damage Your Tractor?
As long as you’re pulling items using the tractor’s hitch and you aren’t pulling or hauling anything heavier than the maximum pulling capacity, everything should be fine.
This is attributed to tractors being developed with high torque and a powerful motor for pulling and traction on heavy items.
Can You Increase The Pulling Capacity?
To improve your tractor’s towing capacity, you need to modify certain things.
For instance, you can increase the pulling capacity by replacing the stock hitch with a more powerful one having several attachment points.
You can also apply mechanical changes to the tractor to increase its pulling capacity. This includes replacing the axles, upgrading the tractor’s suspensions and motor, installing capable braking systems and large radiators.
However, some of these modifications will cost you more money.
What Can You Pull With A Tractor?
When discussing a tractor’s pulling or hauling ability, the first thing that gets to mind is farming tools.
Apart from farming tools, you can also employ your tractor to pull additional items, such as:
In short, you can pull any item as long as it’s legal in your jurisdiction, and the tractor’s maximum pulling capacity is a few lbs above that item.
Why Can’t Tractor Go Faster?
Theoretically, tractors can go faster. However, they won’t achieve their main purpose: to pull and push large goods and items in agricultural work.
If tractors were to function at a reasonable speed, they would require extra-large gear sets to do so. However, this would be pointless, especially when comparing the time tractors spend on the fields and how long they spend on roads.
Why? Adding new gear sets would be very expensive.
So it finally comes down to a simple choice. Should your tractor drive fast without the ability to pull things?
Or should it drive slow but be able to do its job effectively. With the major role of tractors being to pull things, we already know which one will win.
What Is The Tractor’s Average Speed?
Most farm tractors are designed with a top speed of about 40 kph. However, that doesn’t mean that there are no tractors with more.
For instance, there is a Guinness World Record for the fastest tractor at 130 kph in Finland. But, you won’t be seeing any of such tractors in the field any time soon.
Since farmers spend so much time in tractors, they should feel comfortable. Several tractor brands are producing improved tractors daily.
Some tractors are even designed with air conditioning. Others have satellite receivers for receiving GPS signals for guidance and steering.
The aim is to produce quality tractors that make planting, ploughing, and fertilizing easier.
The tractor’s pulling capacity depends on torque and horsepower, meaning they can be modified to offer much power.
Tractors usually offer more torque at low RPM thanks to lower gearing than trucks and cars.
Ensure you load your tractor according to its pulling capacity. Also, consider the factors that affect a tractor’s pulling capacity.
We hope that your tractor offers the best service on your farm.
