Box doesn't reduce cooling. It's about 3-4 inches in front of the grill, which is about 6 inches in front of the radiator. I've not been able to get that 6000 to go past the mid-point on the temp gauge on the hottest day, pulling a 7ft cutter in 3-4ft pasture grass. Box right now has the complete Mahindra tool kit, 2 1/2 lb machinist hammer, 22 ft of chain, 2 clevis', a bunch of pins and is only 1/2 full. As you may already know, getting to the battery or top of the engine is somewhat difficult to do with the FEL frame the way it is. All I have to do is either climb up and sit on the box top or take the box off the angle and put a plain 2x6 across and I have a platform to stand/kneel on. If I ever need to use the lights/night work, just take off the box and turn on the headlites. BobG in VA
