the TM60 was the first all Marshall tracked shovel design, but built at Fowller's in Leeds, previous shovels being Marshall/Fowler/Bray hybrids. It used the Perkins 4.270 engine from the TM 55 with a 3 speed version of the gearbox from the TM 70, final drives from the 55/70 but the side covers were made to give the machine a rear weight bias as required by a shovel. Tracks were based on those used on the TM 70. A later version was introduced as the TM7S, which differed only in the use of the standard 5 speed gearbox from the six cylinder Marshall crawler tractors
