Depends what your projects involve. Personally, I keep the toothbar on in winter...the ground is frozen and I go to work on the burn piles and pushing around stumps and fallen tree debris that can't be done during the wet season. Winter is heavy work season for me, so I keep it on. I also like to backdrag over my crushed rock driveway to loosen it up a bit for some traction on the incline. Since I usually backblade the snow with a rear grader blade, I don't have the need to use my loader for this function...so the toothbar stays on in winter. That's me though...there's plenty of others with a wealth of tractor experience that will do the oposite. The nice thing about toothbars is they are very handy and come on/off easily with minimal time and effort...especially if yours is set-up to swing back into the bucket for storage. Enjoy!
