foster wheels

[windmiller78]

that may be the case piers, but having had drums on all three, they travel the best by far on wooden wheels, they are much smoother, iron is very harsh on the machines especially on the rough lanes round here, rubbers unless pumped up really hard are u/s and tend to bounce, timber is much better and flexes with the terrain, provided they're in good order timber wheels are preferable to the others, that said there's a bit of work in repairing/ making new ones, though I've now got all the gear...
