An Interested Spectator Posted March 2, 2007 Share Posted March 2, 2007 In repect of a device used to improve tracton on two wheel drive tractors. Have heard this refered to a few times but have no idea what it is. Those who are long time readers of Classic Tractor, if you recall the article about the Leyalnd with the mid mounted reach mower that had done very high hours. The owner used a strake to improve tracton. Quote Link to comment Share on other sites More sharing options...
Dwross Posted March 2, 2007 Share Posted March 2, 2007 A set of spike/ blade like devices which are extended past the side of the wheel and tyre when in the field and retracted for road work. The set I remember was retracted and extended by slackening some bolts then driving forward. might be able to find picture over weekend David Quote Link to comment Share on other sites More sharing options...
Lord Ferguson Posted March 2, 2007 Share Posted March 2, 2007 As stated above... but I don;t think they had to be adjustable.... merely fixed to the wheels... A lot of early traction engines ran on "straked" wheels... before most were converted to rubber "road wheels" I believe.... Quote Link to comment Share on other sites More sharing options...

NIGEL FORD Posted March 3, 2007 Share Posted March 3, 2007 DENZIL SKINNER even made a set to fit to his 1/16 Nuffield Universal BMC dealer-only promo model, I think they were the DARVILL design/manufacture. I have ploughed up "shed" strakes in the past, the type that were individually extended and setscrew pinched in position on heavy cast lugs as opposed to the all steel type that all extended together when activated.

britainswomble Posted March 3, 2007 Share Posted March 3, 2007 A set of spike/ blade like devices which are extended past the side of the wheel and tyre when in the field and retracted for road work. The set I remember was retracted and extended by slackening some bolts then driving forward. might be able to find picture over weekend David A company called Stanhay made them. I think they were made in Essex and were painted a Mid blue colour. They were retractable by undoing the two nuts in the centre and reversing the tractor. They worked nearly as good as four wheel drive on our 3000. Not sure if Stanhay are still going but if my memory serves me well, I think they used to make potato planters and harvesters too. ::)I also think the Stanhay strakes were called "Stanhay Darvill" Quote Link to comment Share on other sites More sharing options...
