The powerking 2414 I have was converted years ago (when new) to run this thrower. V only seen it in operation twice in my life. I dragged it out of the woods in september after inherit from my father whome had it as a kid. Once attached, none of the other impliments can be used and also requires two link belts to go around the crankshaft of the engine. The belts are slipping in the off position. Once u pull the lever to tighten the belts, the blower will engage.

so i tried hooking it up today to move it. just a mock up but with frozen bolts i didnt really bother going too far. the blower attaches with two pins in the middle and then just rests under the 3 point hitch by gravity go figure. unfortunitly the pins that attach the blower require the mule pulleys to also be attached to the tractor. more work if you know that i mean.

And now I'll get everyone up to speed with today's event.
Oh what a day. We had beautiful snow for throwing. 5" of fairly dry fluffy snow. Tried out the blower at full rpms, bogged down and clogged within 4 ft. Did that several times before I took a link out of each belt. That was the ticket! Would throw snow about 7ft in the air and looked glorious doing it. Then the fun started...


I took yet another link out of the beltS and yet again beautiful performance. Made two swipes by the wood pile and things came to screeching hault. This is when I relized the clutch lever for the blower needs to be modified so it's higher up and easier to get in a panic. Shut the tractor off to stop burning the belts. The blower was seemed solid and full of snow. After digging it out and groping the insides, found a chunk of metal jamming the padleS I tried rocking the tractor backwards in hoping t spin the blower in reverse. No dice. Ended up taking a 4 ft pipe wrench to the blower driveshaft to turn it backwards and release the metal.

After that it started throwing belts off. The forwards most belt would come off and the rear belt would jump to the forward pully. Did this twice before finding the idler pully arm loose and encuraging belt derailment.

Removed the arm. StuddI ed how it's supposed to work and relized the bushing was seized. Ended up sticking it in the fire place and heating it. Applied marvels mystery oil and beat it into agreement with a hammer. Lubed and reinstalled.

No more throwing belts!

Started making my way in 1/1 across the yard to our neighbors (rents in law), giving her the supper the whole way.

Then she sounded funny. Laboring more. Noticed puffing from the pcv cover and throttled back. Then stalled and wouldn't restart. I was worried it was out of gas but checked and it wasnt. After 5 minutes it restarted and noticed a very loud lower end knock at moderate/no load and any rpms. I checked the oil and it's full. Pulled the spark plug and it's dark gray but not white. Checked the high speed miz and it's 3 3/4 turns out. I had also verified high rpms were 3600 when wide open, no load. I'm going to pull the head tomorrow and have a looksy.

Always wanted to rebuild, mod this engine

That is a heck of a blower you got there.  Would be nice with a hydraulic motor mounted on a skid steer.  Kind of looks like more blower than the tractor engine can handle.  I don't like running those old engine at full throttle.  Always back them down at least 10%.  I figure they will last longer running them that way and don't give them all the load they can handle.  Take it a little easy, get more done and less repairs.  Most of the engines are older than I am and I don't like running a WOT either any more.

Does look like plenty of blower for 14 HP but should be fine if you are not impatient.Sure would be nice to see a video of it in action when you get here back up and running.

I would like to put that on the front of my groundskeeper, it looks to be quite heavy.

IWould love to post a video but not going to happen now. I had it out today, engine knocks but runs. Took abother link out of both belts and she was running sweet even at part throttle. Then the drive chain for the screws said adios. Carnage on the aluminum screw and bearing. I ended up removing it and reinstallING the plow blade. See what happens in the sprig
