There should be two dipsticks. The one for the engine is on the right in front of the starter. The one for the transmission is on the left about under the middle of the gas tank. You can find downloadable manuals at www.gravelytractorclub.org under the Resources tab. The Gravely manual will give the correct lube for the transmission. You may need to look up a Kohler manual for the engine lube. The GTCOA website also has an operators manual for the Rotary Cultivator (New Style). It addresses lube for the gearbox but not for the chain.
