Understanding Clamp-On Duals for Tractor Traction and Flotation

Understanding Clamp-On Duals for Tractors

Installing clamp-on dual wheels is a great way for farmers to increase traction and flotation when using their tractors in muddy or soft field conditions. Clamp-on duals can provide a wider footprint to help the tractor tires stay on top of the ground rather than sinking in. This allows farmers to start planting or harvesting earlier after rain before the fields are fully dried out.

How Do Clamp-On Duals Work?

Clamp-on dual wheels get their name from the way they clamp on around the existing rear tires of the tractor. Most kits come with all the mounting brackets, bolts, clamps, and extensions needed to bolt an additional wheel next to the original wheel.

The dual wheel halves and rim are first assembled together with the provided bolts and rim clamps. This whole dual wheel assembly then clamps onto the outer edges of the tractor's rear wheel using brackets and tension bolts. Once installed, it essentially widens the tractor's stance with a second wheel running next to the original.

Benefits of Adding Clamp-On Duals

There are several key reasons why installing clamp-on dual wheels can be beneficial for tractor owners:

• Increased traction - The wider stance and increased surface area contact patch provides more grip.
• Increased flotation - More surface area means the tractor is less likely to sink into soft ground.
• Increased load capacity - An extra wheel per side helps support heavier implements.
• Wheel spacing flexibility - Dual spacing can be adjusted wider or narrower as needed.
• Increased stability - Duals provide a more stable base that's less prone to tipping.

Considerations When Choosing Clamp-On Duals

If you're thinking about adding clamp-on duals to your tractor, here are some things to consider:

• Tractor compatibility - Make sure to get a dual wheel kit made specifically for your tractor make and model.
• Tire size match - The dual wheels should match the diameter and tread of your existing tires.
• Weight allowance - Check your tractor's specs to make sure the added weight of duals won't exceed capacity limits.
• Power needs - Wider duals increase rolling resistance which requires more power to pull.
• Turning clearance - Ensure duals won't contact tractor chassis or implements when turning.

Choosing the Best Clamp-On Duals

Choosing the right clamp-on duals for your tractor depends on several factors. Here is an overview of key considerations when selecting dual wheel kits:

Tractor Make and Model

It's crucial to choose a dual wheel kit specifically engineered to fit your exact tractor make and model. Trying to install a universal or improperly matched kit can result in bolting issues and unsafe use.

Factory vs Aftermarket Duals

Tractor manufacturers offer factory-approved dual wheel kits for some models. Aftermarket brands provide cheaper options but may have variability in terms of fit and hardware quality.

Tread Style and Depth

Consider whether your fields require more open rib tread for mud or deeper lugs for heavy soil. The dual's tread impacts traction and should match your tractor tire's tread depth percentage for even wear.

Spacer Width Adjustability

Some dual kits allow you to slide the wheels in or out on the mounting brackets to customize the widened stance. Others have fixed bracket widths. Flexible spacers accommodate a range of flotation needs.

Weight Ratings

Make sure the total per wheel capacity of the dual kit meets or exceeds the weight of your heaviest loaded implements. This ensures safe operation and reduced stress on the components.

Installing Clamp-On Duals

Once you select the right dual wheel kit for your tractor, proper installation is key for safe functionality. Here are some installation tips:

Read All Instructions

Before starting, carefully read and understand the complete installation guide provided with your specific kit. Review all parts, tools required, and sequential steps.

Safely Lift Tractor

Use appropriately weight rated jack stands or ramps to safely lift the rear tractor axle so wheels spin freely during the process. Ensure the tractor is stable and level before working underneath.

Torque Bolts to Spec

Using a calibrated torque wrench, tighten all rim clamps, through-bolts, brackets and mounting hardware to the torque values specified in the manual. This prevents dangerous looseness later.

Perform Final Safety Checks

With duals installed, spin the wheels and check for clearance issues, wobble, alignment, and abnormal noises before driving. Recheck torque values after 30 minutes of use.

With the right technique, adding clamp-on dual wheels to your tractor can significantly boost its performance in the field. Just be sure to take the necessary precautions for proper fit and installation safety.

FAQs

Do clamp-on duals damage my tractor's tires?

No, properly installed clamp-on duals will not damage the tractor's tires. The dual wheel kit clamps securely to the wheel rim edges rather than contacting the main tires. Dual treads should match original tread depth to prevent uneven wear.

How much do dual wheel kits cost?

Clamp-on dual wheel kit pricing typically ranges from around $500 up to $1500 depending on the tire size, construction quality, brand reputation, and features. Shop around for best pricing from dealers and equipment retailers.

Can I adjust the width of the dual wheels?

Some clamp-on dual kits allow you to slide the dual wheels inward or outward to customize the stance width. This adjustability accommodates various flotation needs. Other budget dual kits have fixed width wheel spacers.

Will installing duals hurt my tractor engine power?

Yes, adding dual wheels increases the rolling resistance which requires more power to pull. Make sure your tractor has enough surplus power capacity to operate duals efficiently based on the manufacturer's guidance.
