By Wild Bill in Richmond VA

I was asked about the SR-64 Speed Reduction kit by a member here and I knew they made 2 versions, the first was for the early 1960's models and the second was for the late 1960's models. Well, what could be the difference I mean it consisted of a big 7-inch transmission drive pulley, 2 idler pulleys and a bent belt guard ???? Now the early 1960's Wheel Horse models did not use the metal tang at the lower front of the belt guard used to slow the belt speed down to shift gears and from 1965 and later Wheel Horse models used a 2-inch metal tang on the lower part of the belt guard up at the output pulley of the engine to slow the belt down. The belt guard was made with 2 front mounting points, 1 for the Tecumseh and 1 for the Kohler engines. With the 7-inch drive pulley the tractor could move at a much slower rate that would be needed for snow blowing or using a tiller.
