Speaking of Hydraulic Lifts, the Love Tractor Company (or perhaps more accurately Love Industries — I’m not clear on the difference) made a lift and also sold a willys-engine powered tractor.
According to the Standard Catalog of Farm Tractors 1890-1980, by C.H. Wendel, Love Tractor offered model J51 that was built around a Willys CJ-2A engine. This may have been a repurposed Empire Tractor, because at least one source suggests Love purchased eighteen Empire Tractors when Empire dissolved. Anyone know more about the ‘Willys’ Love Tractor?
Love Tractor also created a hydraulic three-point lift system. At CJ3a.info is a page devoted to the lift. At the Farm Jeep site is a scan of the brochure.
The February 1947 issue of Popular Science has an article on the Love Hydraulic Lift System distributed by Newgren.
There is also an article about the Love system and Newgren in a 1949 issue of Farm implement news – Volume 70 – Page 56.
