Since a BCS or Grillo walk-behind tractor will typically outlast the original engine, we offer selection of replacement engines to re-power your old machine. Our selection is based on the best deals we can find to offer our customers, and changes from time to time.
For folks who have an older 600/700 series BCS machine with an ACME engine on it, there are 2 options:
We can sell you an “adapter/clutch kit”, along with any of several “USA Standard” engine types, listed below. The adapter/clutch kit is REQUIRED to mount any North-American-standard engine, because all N.A. standard engines have American-measurement crankshafts & bolt-patterns, and will not directly fit a BCS Machine like the ACME engine did. (All NEW BCS or Grillo tractors with Honda, Yamaha, Briggs, etc. engines on them have this adapter & clutch mounted at the factory.)
MOST POPULAR: We stock a “European version” of the Kohler 9.5hp engine, which has a European tapered crankshaft and Euro 6-bolt mounting pattern, so it is a DIRECT REPLACEMENT for the older ACME engines used on earlier BCS and Mainline machines–WITHOUT having to use an adapter or new clutch!! Since Kohler has actually purchased ACME and essentially discontinued the brand, they offer this new engine in Europe to replace the ACME 8 and 10hp engines. We have special-ordered these engines in an EPA compliant version, and are offering them here in the USA!
We are also offering a special “package” price if you order a new engine AND a new engine guard/bumper at the same time (bumpers off the old ACME engines will NOT fit any other engines)…see “Engine Bumpers” section below for details.
If your BCS has a non-ACME engine on it already, then the USA standard engines below (with ¾” or 1” keyed crankshafts) will fit your tractor directly, because you already have the clutch & adapter for the USA standard engine. All engines configured for “remote throttle” hookup at no extra charge.
–NOTE: If you have an old Mainline machine that was built by S.E.P. (Ladybug, 2+2, 1300, 1500, 1700), the best option is the Kohler 9.5hp engine mentioned above. If for some reason you prefer a different engine, we can also offer “modified” engine adapter kits to fit some of these S.E.P. machines …call for details and pricing, and we MAY actually need to get your old clutch sent here first to make sure the new kit is compatible.

- NOTE: The above adapter kits come with bolts to mount the adapter plate to the engine. These bolts are U.S./Standard threads (first 4 kits come with 5/16”x24 bolts, last kit comes with 3/8”x16 bolts), since U.S./Standard threads is the standard for the “American/SAE” bolt-patterns on Honda, Subaru, Briggs & Kohler engines. HOWEVER, It HAS come to our attention that some of the cheap Chinese-made “Honda clone” engines DO NOT have U.S. threads, or have incorrect U.S. threads (for example: 5/16” coarse thread instead of fine). If you are buying one of these cheap engines, please be aware that any needed non-standard fasteners are your responsibility. We supply the kits only with the standard fasteners mentioned above.
Item G G110 WTKT 18-pound weight kit for above Grey bumpers, with mounting bolts: $35
(NOTE: Bumpers or skid-plates that were mounted on ACME engines will not fit anything but ACME…unless you make it fit another engine by modifying it yourself)
