The Patent Pending oil sight gauge takes the guess work out of
checking the oil. In less than 10 seconds, all three cutting box oil levels can be checked and rechecked as often as you walk around the machine.  Never climb onto the cutter again to check the gearbox oil levels.


       Bush Hog’s E-Z lube drivelines are quick and easy to
service. All grease fittings on the pto CV driveline and wing
drivelines align for quick location of grease points. Since
all grease fittings on all drivelines are in an up position on
every 5th revolution, service times are reduced.
