Massey Ferguson MF 1450 and MF 1650 Garden Tractor Specifications

Specs Hub › Massey Ferguson › MF 1450 & MF 1650

Complete specifications for the Massey Ferguson MF 1450 and MF 1650 garden tractors, transcribed from the factory operator's manual and assembly instructions (Form No. 1448 404 M2, dated 10/77). The MF 1450 runs a Kohler K321AQS single-cylinder engine (31.27 cu. in., 14 hp), the MF 1650 a larger Kohler K341AQS (35.89 cu. in., 16 hp), both at 3600 rpm. Both drive through an Eaton Hydrostatic Model 11-025 transmission and a 2-speed Peerless No. 2518 transaxle — a step up from the belt-driven Peerless units on the smaller MF garden tractors in this batch.

These tractors were offered with three mower deck options: 42, 48, or 54 inches, each identified in the manual by its own model number rather than tied to a single tractor model.
