Some terrific suggestions in this thread for sure.
My thoughts:
1) Chain holder, I go nowhere without my chain and I'm always looking to see where I left it last and its always in the bucket. Pain in the butt.
2) Cup holder, sick of juggling water bottle and ultimately dropping.
3) The inverter is a briliant idea, it would be awsome to be able to have a mini-generator built into my tractor, many would I use that alot.
3a) Cigaret lighter to charge cell phone / blackberry would be very handy.
4) The toolbox thing I don't find myself wanting for to often, if working on something I'm near my all my tools whenever possible.
5) Block heater standard.
6) Remote hydraulic valve.
That's about it for me.
Good thread topic,
Joel
