The McCulloch M11577RB garden tractor lawnmower is pretty much the introductory model in the current line up from McCulloch. The engine powering the M115 77RB is a PowerBuilt AVS engine from Briggs and Stratton. This one cylinder engine is key started with the help of a 12 volt battery. The engine is kept oiled using a splash lubrication system. The engine is rated at 2500 rpm. This lawn mower transfers power from the engine to the wheels through a gearshift system, giving the driver 6 speeds traveling forwards and one for reversing. A similar model to this one that uses a hydrostatic transmission instead is the McCulloch M11577HRB garden tractor lawnmower.

The McCulloch M11577RB has a very small cutting width of just 30 inches wide. The mower deck on the M115 77RB can be raised and lowered from a high of 3.9 inches to a low of 0.8 inches above the ground. Unfortunately there is not actually many different cutting heights for this mower with just 6. However, one of the really cool things about this lawnmower is that the bagger attachment at the rear comes as standard which means that you don’t have to worry about buying it extra. It also means that your lawn will be left looking incredibly neat too. If you don’t want to collect the grass clippings, you can optionally purchase a mulching kit.

The McCulloch M11577RB comes with headlights as standard so that you can continue operating it, even when it’s dark outside. The rear bagger has a capacity to hold up to 200 liters. The total length of the machine with the bagger attached at the rear comes to 2.29 m (89 inches) while it’s total width is 0.88 m (34.6 inches). When compared to other tractor lawnmowers from diferent brands, the M11577RB is very light, weighing in at just 190 kg (418.9 lbs).
