Our New Holland 835 round baler ate itself yesterday. Been nursing it for a bit. We're looking to get another in the price range of £6000 to £7000. We only do about 400 bales a year, just wondering what people would recommend. Best model for reliability etc. we have a 90 horse power proxima zetor and is very hilly where we are so would we be able to have one with knives or we lacking horses!!! Advice??
