The seat on my 2005 Kubota tractor is still pristine, except for a little dirt. The seat on my 2016 John Deere S240 riding mower looks like it was attacked with a machete--cracks, long splits--everywhere. Both are garage-kept. I'm the only one who drives either of them. So, A). Why is Kubota's seat so good but JD's is such cheap crap? and B). I don't want to pay $125 plus for a new JD seat. FlexSeal tape helps but won't lay down around all the curved surfaces on the seat. Any suggestions? Thanks!
