Whilst dual wheels are most commonly used on tractors, they can also provide benefits for combines, drills and cultivators.
Stocks standard range of dual wheels feature heavy-duty clamps, hooks, eye nuts, and eye bolts. Most clamp components are made from heat-treated high tensile drop forged steel, making them the strongest available.
KEY FEATURES
-
High quality rims

BENEFITS
-
Increased traction - increased work rates with less fuel wastage, more hectares for less
-
Decreased compaction - improved soil structure, drainage and plant establishment
-
Reduced deep wheelings - fewer expensive remedial deep cultivations
-
Reduced wheel slip - reduced tyre wear and soil smearing
-
Reduced tyre pressures - improved ride and bigger tyre footprint
-
Increased stability - increased safety on hillside work.
-
Double the tyre beads - reduced chance of tyres spinning on the rims of high horsepower tractors
-
One design only - suitable for tractors of any HP
THE WHEEL
High quality rims up to 8mm thick have a power rail rolled from 50mm x 12mm steel, continuously machine welded into them to provide the anchor for the clamps and to reinforce the rim.
CHOICE
To make life simple there is only one specification of dual for each tyre size, and the number of clamps and other variables are allowed for in the design. All Stocks need is the tyre size, make and model of tractor, and the appropriate dual wheel can be supplied.
OVER CENTRE CLAMPS
The design of the clamp means easy fitting to fixed centre wheels. A unique removable spacer allows the clamps to work correctly when eye nuts are fitted to wheel weight holes or attached to wheel rim bolts.
RIMS
Up to 8mm thick conforming to ETRTO (European Tyre and Rim Technical Organisation) standards, built to your requirements.
SPACER BANDS
Up to 6mm thick are rolled with a rib for additional strength and a precise concentric fit into the tapered bead section of the tractor wheel.
The ribbed band ensures that the duals fit correctly and always run true. They are also easy to remove without becoming wedged and do not loosen when driving backwards.
POWER RAIL
Rolled from 50 x 12mm steel, continuously machine welded into the rim using a special process, to provide the anchor for the clamps and to reinforce the rim. A bolt in power rail option is available to enable adjustable wheels to be used as dual wheels.
THREADED ROD HOOKENDS
Made from high tensile steel, Stocks threaded rods have a thread pitch of 2.5mm to ensure both durability and strength. All forged products conform to British and European standards.
EYE NUTS
Eye nuts are attached to wheel weight holes, specifically drilled holes or rim bolts. A full range of different eye nuts are available to suit all tractors and wheel types (see p.09). They are drop-forged carbon steel, hardened and tempered to BS970, with a tensile strength up to 700N/mm².
FITTING
There is no need to rotate the dual for alignment with the tractor wheel. Wherever the eye nuts are attached to the tractor wheel a hook can be fitted to the eye nut. An over-centre clamp is fitted to the dual wheel power rail and tensioned with the handle supplied. Detailed fitting instructions are supplied with each pair.
SAFETY
The clamps attach to the power rail, which is positioned to the outside of the dual rim, rather than onto the spacer band. It is much easier and safer to fit and tension the clamps in this position without needing to reach deep inside the wheel to make adjustments.
Once the clamps are correctly tensioned, they are locked into position with the supplied “R clips“ to prevent accidental release.
SPECIALIST OPTIONS
Please enquire for any special requests including; extra wide or narrow spacer bands. Colour matched paint is an option, matte black is applied as standard.
VALVE GUARDS
On forestry and other specific wheels, Stocks can fit a variety of valve guards for optimum valve protection.
