You can attach and use any non powered Cat 1 attachment and use it like you normally would on a tractor. If you look back at the pics I posted, the box blade is a 60" cat 1 and the aerator is a 60" cat 1 hookup. One other thing about the Ventrac is that unlike most sub-compact tractors the 3 point easily allows for down pressure instead of just gravity pressure. There are 2 factory rear remotes on it.
I've used the following Cat 1 attachments frequently on the Ventrac - 12" single bottom plow, potato plow (ripper), 60" landscape rake, 60" box blade, 60" aerator, 60" dethatcher.
I don't know about the 2 cyl gas engines but the 3 cyl gas Kubota engine has been around forever and I personally know guys running the same engine in Kubota ZTRs with over 5000 hours on them with no major repairs. That 3 cyl is an entirely different animal than a V-twin. Sounds so sweet too. haha.
No, the gas 3 cyl is not fuel injected, that would be awesome but it's not. It is liquid cooled and has a huge radiator for what it is. Larger radiator than what's on the B2920.
If you want any up close pics or anything just let me know. I won't be back at the shop until Monday but I can get you pics of anything you want.
The thing about the power bucket is that it is "quick attach" in the sense that the other attachments are. Once you get used to it, you can hook up an attachment in literally about 1 minute. The power bucket is basically a tractor with a wheel barrow on the front of it. I do think they make a little grapple for it for moving logs and such but it's ideal purpose is moving stuff low to the ground and keeping it low to the ground, such as moving mulch, rock, etc.... The versa-loader as I said before is the equivalent of a loader on a sub-compact type tractor like a BX or JD 1 series. I've already got 2 larger tractors with loaders so I've never gave it anything thought on the Ventrac.
