The KAB 811 seat in our matbro ts270 is well past its best after 11,000 hours, it squeaks like hell and the suspension is hit and miss, gives me a sore back after sitting in it too long. I thought I should get it fixed before this harvest as I seem to spend the most time bouncing across stubble in it. Is it worth stripping out and putting new rollers in and whatever else it needs or is it better to get a complete new seat? looks like you can still buy them new, £450 from a quick google search which is plenty enough but I'm not sure if you can get parts for them and are they a sod to rebuild or not too bad? TIA
