I had a large frame snow cab that sat in my shed for about 3 years. It was in really nice shape so I decided to try and retrofit it onto my 1669L. Years ago someone gave me the snow cab mount that goes on the dash of a QT series tractor. For some reason I kept that piece in my shed. It turns out that piece bolts right onto the dash of the 1669L.
I removed the front mount from the large frame snow cab and this QT mount fit right on it. I had to make two supports that connect to the rear of the tractor. The supports are flat stock, one end is connected to the bolt that holds the seat pan to the frame similar to how the tube frame cabs mount, the other end bolts onto the back of the seat pan with a 1/4" bolt.
I took the lower front mounts and located them directly onto the foot boards. I used a 1/4" bolt to hold them in place. The cab is super solid I think you could lift the tractor just by the cab frame. I also wired in the overhead lights onto their own separate light switch. I mounted the switch to the left of the steering wheel on the dash. It looks factory installed and came out great. I am anxious to try it out this Winter. Here are a few pictures.
