I have a "fleet" of Sears Suburbans that I use for the bull work--only have one deck to fit them,and I did use it to mow for several years,but its slow compared to the John Deere I have now,you had to use second gear hi range to mow,anything faster,it would leave to many uncut strands showing..the 50" deck was nice for getting the yard done quicker,but was also a drawback as far as using it in areas too narrow to fit the deck in like between trees..
I "think" I have read about guys swapping a K66 into many tractors that had the K46..I thinks it is a shame they no longer make tractors drive trains like they used too...even old vertical shaft Sears and MTD's I had used a Peerless 3 speed transaxle that was almost as rugged as a car transmission..
This is the Sears Suburban I use for dragging logs out of the woods,plowing snow & dirt,and brush piles...I put a tired old 6 HP Briggs flathead on it years ago,I bought it with no engine for $40,and I had a few of those engines collecting dust in my shed--I figured the engine would blow a rod,it sometimes clatters loudly and belches a cloud after each cold start,but once it warms up it stops smoking and gets quieter...it amazes me what 6 HP can push or pull when you have super low first gear & lo range,it can push my truck uphill without spinning a tire at all from a dead stop..
I have three other Suburban 12 HP tractors too,I stumbled across them and couldn't pass them up for the price they were offered to me..
I have a 3 point hitch,mower deck and a plow to share among them,--I had a Haban snowblower from an SS-16 but it proved too big for a 12 HP,so I traded it for the smaller Roper "rotary snowplow" that was smaller--that worked great until the gear box grenaded...still hoping I can find a good used one,but for the most part snowblowers suck here,with the wet slushy snow we get..
I made a John Deere plow blade into a combo plow & scoop bucket that uses a winch to raise the "bucket"..it only lifts about 2 feet high,and has no down pressure, so its not quite as useful as a real front loader,but it saves my back from a lot of heavy lifting..a foot pedal "dumps" the bucket in clam shell fashion..
This is the one I was mowing with till the J-D came along..
Like all old things,they do have some quirks,and some things could be better--for one I'm not that big a fan of the starter/generators they used,they are barely powerful enough to start the engine cold,the dinky battery doesn't always succeed in doing so,and the generator only puts out about 10 amps,which isn't really enough to keep the battery "up" if you use the winch a lot..
I put a GM altenator on the "bull" tractor, I have used it to boost the batteries in my diesel pickup a few times in the winter --it was so easy to adapt using the stock GM brackets I felt this is too easy,something must be wrong--didn't even need to drill any holes!..
