Looky what I got! It started out as a tow behind castering vac for a lawn tractor, got it for $125. Working shape, starts 1st pull runs strong. Well I re-worked it to mount to my 52" TTHP. I cut off the bin tray and welded two peices of angle iron on, it mounts on the deck by just sitting on it then you use the thumb screws on the angle iron mounts to clamp it on. The deck boot I modified to mount like an Accelerator side bagger. The engine I cut the frame away from it leaving a bottom peice on it, then to that welded square tube and drilled a hole in it for a hitch bolt. Then made a mount for the mower frame as a receiver for the engine mounting arm. Then switched places with the hoses (both 6") to get the right lengths and added a stovepipe elbow for extra length on the deck to blower hose. It all hooks up quickly (under 5 minutes easily, probably closer to 3) and without tools. Anybody could use it. It holds alot (around 75 gallons total since it fills up higher than the hoppers inside the net). I also made a handle for the engine unit and a dust/debris sheild for the mower's engine to keep debris that falls out from the back of the unit from getting right on the mower's engine (would clog the cooling intakes and the air filter quickly w/o this). Has a 5hp B&S engine, not bad. Only complaint is that it is not the easiest to see around, but it beats emptying a side bagger every 10' in heavy leaves. You can also line the bins with a trash bag if desired. Mowed 1/2 acre of somewhat tall and very moist grass with it at 4.5mph no clogs and emptied it twice, packed full each time. Only time it clogged yet is if you don't empty it when full (duh!) I'm pleased with it and cannot wait to play in the leaves. I can also mount it to the trailer tongue to use as a truck loader to get piles into my truck (high sides yet to come ) Total investment: $155 and about 3 1/2 hours' labor.
