I really need to level my dirt/grass. I've only got 122 hours on my JD rider and it already needs tie rod/front end steering components. I really don't slow down for bumps while mowing, not the mowers fault, just the operators! Between that mower, the lift and now the tractor I'm seriously considering a battery operated grease gun. Never owned one but have Makita, Milwaukee chargers/tools. Anyone used or own a battery powered grease gun?
