KENDELL, JERRY, ART - Sorry, had to finish up cleaning the shelves in the shop yesterday PM.
I made everything including the impeller & housing for the blower. There's a rebuilt K181 with a dry-type air cleaner on it now. The K161 with oil bath air cleaner was off an old CCO Dad bought Years ago and sold about 5-6 yrs ago to someone in Ohio and I had to return the K161.
The impeller is on a 1" dia. solid steel shaft, impeller hub is 4" in dia. and I had a machine shop bore it and turn a step on the face. A 3/16" thk round steel plate is welded onto the step & OD of the hub, and four 3/16" thk paddles are welded to the hub & side plate. Only purchased items were the tire & wheel, and the two pillow block bearings the impeller shaft mounts to, and the weld-together pulley & hub that drives the impeller. The K181 also has the PTO clutch off the K321 mounted on it now to engage/disengage the impeller. Ohhhh, I had to buy a new throttle cable, but I actually made the throttle control, & yoke for the swiveling wheel, gas tank, etc.
The vac unit is on about Engineering Revision #3. I had the blower originally sitting 90 degrees to the direction it is now towards the right side of the unit and the engine towards the left side. Blower didn't work at ALL.
The cart is an el-cheapo but measures 32" wide, X 48" long and inside height is 36". There's a back door for it but the day I took those pic's I took it off to haul trash to the burning barrels.
I have a special set of blades for the mower with tall wings on them to really throw the material into the chute attached to the deck. A set of Gator's would work great if they made them for the old 38" decks. It doesn't leave the yard quite as clean as a sweeper would but it's a 1-man job now and the loads dumped on the pile are MUCH bigger.
Back when SON was younger He enjoysed pulling the lawn sweeper with His 129 and I'd haul to the burn pile with the 72 & cart without any sideboards on it. We'd mulch the leaves, then sweep. One fall We worked six weekends in a row at least one whole day each weekend.
Best day I had with the vacuum was 4-5 yrs ago on Veteran's Day, I started with the vac about 12:30-1 PM Friday and got done with the leaves at 2 AM Saturday morning, about 14 hrs straight. The 72 ran out of gas a couple times, but I managed to make pit stops most of the time. I aerated the whole yard twice on Sunday also with the 72. I put 25 operating hours on the 72 that weekend alone.
I figure the weight of the whole unit loaded with leaves/clippings has to be right around 2000# No wonder the tired old K241 struggled pulling it and the mower!
I looked at vac's for years also, found one made by Ohio Steel Fab. who also made my moldboard plow, but a service tech at the dealership bought it before I even saw it. Probably 16 yrs ago DAD saw a CC & vac unit sitting along US Rt 6 east of Moline. He told Me about it and I told him to buy it for Me, just the vac, and the seller would not sell it separate. I wasn't going to pay $1000 to $2000 for a cheaper lighter unit so I built one. Including the cost to rebuild the K181 I have about $500 in this thing. Steel was a LOT cheaper back then! I hauled home just over 500# of steel for about $135.
