Our most recent preservation...a 1968 Gravely 424. It ran, but leaked oil and smoked badly, when we got it. We added a Front PTO Kit and Rotary Plow. Looks and runs great now!
Here is a sample Before and After image of a 1973 Gravely 810 we Preserved and recently sold. Someone had replaced the original 10hp engine with a '75 model 14hp, and we added the Front PTO kit, a headlight (the 810's didn't come with them) AND a hydro kit. We effectively had an 814 with Hydro when we were done. This machine had MANY more years of service left in it for sure!!
