In 1947 John Deere replaced the pan seat with an adjustable cushioned seat on models A, B & G. Note this innovation occured in conjunction with John Deere’s introduction of gasoline engines for the A & B models. (see photo to right) Uses backrest JDS272L (black) or JDS271L (yellow)
With the introduction of the number series tractors 50, 60 & 70 in 1952 several new improvements were featured. The cushioned seat frame was redesigned. The new design incorporated a new seat back that was not interchangeable with the seat back used on the letter series models. (see photo to left) Uses backrest JDS272N (black) or JDS271N (yellow)
Through the years some tractor seats were replaced with assemblies off of other models. For example, John Deere models A & G have seats which are interchangeable with (John Deere) models 60, 70 (& 620 – 730 models w/ standard seats). The cushioned seat on the John Deere B is more often original as it only interchanges with the 80 (& 820, 830 models w/ standard seats.)
As the difference in appearance of the seat frames is obvious, a quick inspection should reveal if your tractor has the factory seat and help you when picking out the correct seat back rest.
We have two similar looking back rests but be careful to notice the differences when ordering. Click on picture below for larger image.
