MF 7/8

INTRODUCTION

Wherever there's grass or snow there's a job for a Massey-Ferguson Lawn Tractor. There are three capable models; the MF 8 H, the MF 7 Electric Start and the MF 7 Recoil Start [there was a MF 7 hydro]. The MF 8 H has a hydro­static transmission and the MF 7's have a standard, three-speed transmission.

The MF 8 H is powered by an air-cooled, eight horsepower engine and the MF 7's have seven horsepower engines. By using the Hydra Speed Lever or gear selection, slow forward speed is possible with maximum engine speed, providing full power for implements such as the Rotary Mower or Snow Thrower. In close quarters, use of first gear or adjustments of the Hydra Speed Lever permits creeping around trees or buildings. When the congested area is passed, shifting gears or moving the Hydra Speed Lever permits operation as fast as conditions warrant.

MF Lawn Tractors may be used with the MF 710 Rotary Mower, MF 720 Snow Thrower, MF 730 Front Blade or MF 641 Dump Cart. Other useful attachments include sprayers, spreaders, rollers, lawn aerators, lawn sweepers and other light-duty, pull-behind equipment.

MF 8 H and MF 7 Electric Start Tractors may be equipped with a cigarette lighter, headlights and tail light. In addition, tire chains, wheel weights and chrome wheel covers are available. A speed reduc­tion kit may be used with MF 7 Tractors for maximum power at minimum speed (recommended for use with MF 720 Snow Thrower).
