1. Farmers, growers, processors and industry representatives are being asked for their views from 31 August for 10 weeks on the role of the Agriculture and Horticulture Development Board (AHDB).

    The AHDB is a UK statutory levy board, funded by farmers, growers and others in the supply chain. As we leave the EU, there is an opportunity to ensure that the sectors that the AHDB covers are as competitive as possible. This review will look at the AHDB’s purpose and priorities, its strengths and where improvements need to be made.

    This is a joint 10-week exercise covering England, Scotland, Wales and Northern Ireland. The request for views will close on 9 November.

Ford power steering

    Hi
    My old Sanderson has an annoying steering problem and I wonder if anyone can give me some advice
    It generally steers fine but occasionally it just refuses to steer any more than a bit, getting any lock on is difficult to say the least. Hardly noticeable when traveling but when actually moving stuff can be a pain. It even proves difficult with a good load up front.
    I've resealed the pump and changed the filter (what twit designed that set up?) Fluid stays put no froth so not cavitating.
    Any suggestions welcome.
    Thanks

    What type of had pump did you reveal @ mikep as I could have a priority valve fitted to it.

    It's the Ford tractor pump as in 5000 so dedicated steering. May be worth having a look at the orbitrol unit @Kevtherev but I thought they were either or?

    Find priority valve. Pull it it out and clean it, may be polish it with something suitably gentle. Likely a bit of fluff from ram seals blocking it. Our 725 used to do it all the time....

    No priority valve as it uses the tractor pump.

    Are we sure as the info I have shows a steering pump for the Ford 5000 to have its own tank and priority valve in the front cover. If we can get some pictures we can hopefully confirm what pump is actually fitted.

    It's the all in one pump/reservoir. Can't think it would have a PV as it only feeds one circuit.

    Stick an oil pressure gauge on a tee piece on the output from the pump and see what you have when good and when bad?
    Also worth checking the kingpin bushes and bearings, one might be going to seize.

    Edit:
    The tight bush will just make the relief valve in the pump open .......

    A tight bush makes my 'relief valve' open and pump as well:ROFLMAO:

    Will try that but it could actually be the prv as when it is playing up you can only get a small turn either way then nothing no matter how hard you rev it's solid.
