Back in the late 60's and until the mid 70's I worked at a short line dealreship that rented tractors. We handled Modern loaders and Servis now Rhino, and Bush hog loaders in addition to all the other equipment they made. Leon was a very good loader. I had a Leon Dozer Blade on my 4013 JD about 30 years ago, and traded it to the JD dealer for a Farmhand Loader for the 4010. The Leon blade was very heavy and neighbors would borrow the tractor to try to use it as a bulldozer. It broke a spindle and wore the lug holes in the front wheels. When I had to replace the transmission countershaft due to being overloaded, I decided the blade was just too big for that tractor. We got a lot more use out of that loader and I still have the tractor and loader nearly 40 years later.
