Peteleft,I do not think the plow for the Compact I knew of will fit,after seeing it--the Compact has holes drilled in the front axle (that is different than a Suburban is)--and brackets on the chassis to bolt the plow frame too,while the Suburban uses a "U" channel shaped peice that slides into the front of the frame to mount the plow,and welded tabs on the front axle..completely different setup AND plow blade!..looks to small to be used on a Suburban,not wide enough !.
You'd be better off adapting a plow from some other Sears or any other brand,unless you can find a Suburban plow setup locally..it's not a hard tractor to adapt things like that too really..I'd like to add hydraulics to mine by using a GM P/S pump to lift the plow and 3 point hitch,maybe make a loader someday too..
Yours is in about the same shape as my two 12HP ones are,and the same color!..I bought a new Muffler for one of mine at Lowe's for 5.99,an "Arnold" brand,that looks very similar to the stock OEM one!..took some doing to get a pipe elbow to screw into the engine ,the threads were full of carbon hard as coal from being run "open headers" so long!--..
I had to use lots of diesel fuel and penetrant to get the pipe fitting in,a turn at a time,unscrew it,back and forth--couldn't find a 1" pipe tap for less than 50 bucks here,nor anyone to borrow one from,so I decided to be brave and hope I could get that fitting in without cracking the block,it's very thin there!--no bolt holes in those HH Tecumsehs for a bolt on muffler either,so if you lose the pipe threads, your boned..but it eventually went in all the way no problem..
Carbs seemed to be a big pain on these engines,that and the solid state ignition,both can be hard to find and costly if either go south--one of mine refuses to idle,only if I set the idle speed above 1500 rpm will it run at idle,anything lower it shuts off..and I've cleaned the carb thouroghly too,and it was clean to start with --adjusting the idle mixture screw makes no difference no matter where you set it,so I assume the carb has a defect in the idle curcuit,like so many Tecumseh's do..I'll have to live with it..
Isn't it amazing how well these things held up over 40+ years,especially after being left outside?..mine all have all 4 original tires,they are cracked,but hold air OK so far,only one front tire is junk on one Compact out of all of them!--and the paint has held up remarkably well too,there is some surface rust on the tractors and hood but no rot--the deck and plow could use sandblasting though--but for being left out in the harsh climate here that long,they have held up very well..
I had to offer some green to get the dozer blade because he had last-minute thoughts about keeping it. He figured it would mount onto a '72 Custom 10E that he also has (maybe one for the future for me).
