Small progress.

Spent most of today on Mowers.
Finally managed to take the broken Hayter into the workshop, expert opinion is that it is a broken valve. Will take about three weeks as they are full to the gills with broken machinery.
Had a look round for alternatives, all the DIY warehouse options are fine for the engine, but, and its a big but, the deck and handles are so flimsy and ready to rust. Anything of quality is too dear for my pocket as new, so a secondhand Hayter looks good at just under £200, aluminum deck, sturdy handles and the one we saw had a replacement engine a few years ago.

Eventually got on plot a bit late in the evening and cleared another thirty foot row, just two left to do. Then interrow "cultivator" hoeing, followed by earthing up.

Need to get more brassicas planted out, I've got them in pots and seed bed, but keep failing to get them out on the plot. Now I've sorted out some wire netting I can, hopefully, keep the pigeons off.
