This is my BCS 730 powered by a Kohler 8 HP Magnum. I purchased this the winter of 2008 and had it shipped from Redmond WA to my place in Lodi, WI. It was bought to compliment my 850. I mounted the 6 by 12 inch tires only for this project. Most of the time, it runs around on a pair of 4 by 8 stock tires or the 5 by 10s off my 850. It has home-made extensions in order to get the 4 bolt trailer rims to mount. They won’t line up without the extensions. I welded a 1 inch piece of solid round stock in the middle to hold standard free weights. The brackets can hold about 100 lbs of weight each side. This was an idea taken from Joel at EarthtoolsBCS.com. It has the Free-wheel devices to help in turning. They have their drawbacks, but I like them alot for use on this machine. I can lock them solid, make them free-wheel, or set them to ratchet either forward or back. Setting them to ratchet takes away reverse, and will allow the machine to get away from you when going down a slope. My 730 also runs a 26 inch tiller I bought out of Montana in the spring, a 28 inch snowblower I bought out of Chicago IL in the winter, a chipper I bought with it, and other attachments.
The Plow was bought from Jim at Fields Farm in Bend, OR. He says it’s a Mainline attachment. Mainline sold BCS machines under thier name until 1982. BCS then started importing their machines on their own and Mainline started selling SEP machines under the Mainline name. This plow is probably made by a local shop in Ohio, where Mainline was based.
The plow does a good job of digging up the potatoes. Unfortunately, it also re-buries about half of them. They either need to be found by digging through with your fingers, or the bigger ones can be found with a 5 tine manure fork. I have some ideas on how to tweak it and will see what next year brings…

This time out, Makita’s SP6000J1 deserves “Best Value” kudos. It cuts exceptionally well at a price far below some others. And for “Best Bet,” Festool wins by a nose over the more costly but equally proficient Mafell. The TS 55 offers solid cutting performance and superior dust control in a user-friendly tool.
