Notice the waterfall flow of Sprinkler Lube as it sufficiently covers the gears giving adequate protection, even if your gearbox is low on lubricant.
Sprinkler Lube is formulated with sticky properties that allow the lubricant to stay on the worm gear shaft and make its' way into the bearings to give you the ultimate protection.
Sprinkler Lube's thixotropic viscosity means that you get the benefits of both a gear oil and a grease. Thin where it need to be thin to flow and protect, thick where it needs to provide long term protection. SL 1200 and 1200 OT are formulated for the rigourous environment of your pivot gearbox to provide you with the protection you need, for the results you want!
The lack of flow with normal gear oil is evident. Unprotected gears means damage to your gearbox, downtime with your pivot, and lack of water for your crops. All of this adds up to higher costs, less profit, and less satisfaction with your results.
Normal gear oil does not provide a sufficient flow of protection and it drains off of the gear shaft and gear teeth when the lubrication level is low. This dry start condition means that your gear teeth are metal on metal when the gearbox moves. Normal gear oil does not have the EP additive system to overcome this issue. The result is a damaged gearbox.
Normal gear oil leaves the bearings dry and allows corossion to cause damage to the inside of your gearbox. Each time the pivot starts, the lack of lubrication is allowing metal on metal contact, damaging the bearings, causing misalignment, which increases the load placed on your gearbox and in extreme cases can cause your gearbox to lock up.
