I bough a 1991 ,to the best of my knoledge, argo vanguard 8x8 with a B&S 16HP V-twin last winter with a set of 13 inch argo plastic tracks. but over the summer we had a huge forest fire the claimed many cabins and even came so close to town we had to evacuate. during all that I lost everything I had stored at my fathers cabin, Cabin survived luckily as it was only built the year before, everything I had stored was my winter fleet which was 4 snowmobiles and my argo tracks!
so my latest project is the argo, I am using three 20" snowmobile tracks with wheel guides for tracks and I will be swapping in a 3 cyl kubota diesel that is 22-24hp (cant remember which) I had this engine in my alpine snowmobile but latter put a 2 stroke back in due to weight, that was one of the ones that burned so I'm glad I did that now.
here is the diesel, I wont start that swap until the tracks are done.
here is the argo last spring cutting some wood with the dogs.
for the guides I used 1.5"x3/16" flat bar 9" wide and 4" height. I bet them in this rig with a small sledge hammer
they are spaced 7.5".
jig made for drilling holes.
marking and drilling the tracks.
the length on the track roughly to the gas can.
next I added a flare to the guides to help them stay onto the tires. made a quick and crude brake.
and today I managed to get the argo into the garage and bolt up the guides.
wrapped the track on to get a final length measurement.
with the snow this went threw with 13" tracks I cant wait to try these 20" tracks! winter is very long up here and the argo gets used more in the winter then summer so good tracks are a must for me.
