The BCS 852 combines the best of both worlds: a third working speed AND a fourth transport speed for even more versatility. The difference between the 852 and 853 is simple: the transport speed can only be applied in rear-mount (tiller) mode on the 853; the transport speed is only available in front-mount (mower) mode on the 852. These are the only BCS tractors offering a transport speed and a third working speed. The transport speed disengages the PTO, and is intended to do just as is sounds–transport! Only riding implements (sulkies, Utility Trailer) can be utilized when the transport speed is engaged. In addition to the Differential Drive with Lockout being standard on all BCS Professional Series models, the 852 features individual wheel brakes for increased maneuverability—especially helpful when making frequent turns. The 852 comes with a Honda GX390 engine and is available in recoil or electric start.
