Bolt-In Dual Wheel Adaptors

An adaptor to allow our standard adjustable row crop wheels to be used as a single row crop or as a dual wheel alongside another row crop or standard tractor wheel. With the bolt in the spacer bands removed, the row crop wheel reverts back to single use.

Combine Dual Wheels

These are particularly suited to this method – most large combines are fitted with a 32″ diameter tyre of various widths and profiles but most of these have a very similar SLR. A standard 20.8 R38 tractor tyre will work as a dual alongside most of these 32″ combine tyres and provide very useful flotation and traction at very modest cost, and without putting massive strain on the combine axle and hubs.

Standard Dual Wheels

Our standard range of Stocks Duals are the strongest dual wheel available and feature heavy-duty clamps, hooks, eyenuts and eyebolts. There is no need to rotate the dual for alignment with the tractor wheel. Wherever the eyenuts are attached to the tractor wheel, simply fit a hook to the eye nut and an over centre clamp to the dual wheel power rail, and tension with the handle supplied.

Step Up / Step Down Dual Wheels

A design enabling two wheels of different diameters to be dualled together when the two tyres have a similar static loaded radius Generally uses a smaller and narrower wheel and tyre as the dual. For example, a 13.6 R 48 dual tyre alongside a 20.8 R 38 tractor tyre will reduce the overall vehicle width to match an implement or make roadwork easier, or a 20.8 R 42 dual tyre alongside a 710/70 R 38 tractor tyre offers less expensive dualling than using two 710 tyres.

Straddle Row Dual Wheels

Extra wide spacer bands can be specified to allow the use of dual wheels for inter-row work. These are custom built to the required row spacing and can be either standard tractor sizes or row crop sizes. Note: The centre discs of the tractor wheels may need to be reinforced to withstand the additional loading due to the extra width and consequent leverage. This is more relevant when using row crop wheels due to the larger diameter discs (more leverage) and higher tyre pressures (harder ride).

Triple Tractor Wheels

All our standard Stocks Duals can also be used as triple wheels. Simply use the same size again, coupled onto the tractor wheel using clamp assemblies with extra long hooks. Some tractors are better suited than others for triple installations, for example, those using bar-type axles.
