Engine outputs are mechanical shaft power at the stated speed. Compare the 3000 rpm and 3600 rpm ratings separately.

Fuel-consumption and runtime figures are values listed in the model source. Request the load point, fuel or tank basis and test conditions for a like-for-like comparison; actual consumption and operating time depend on the operating conditions.

Questions about 173F – 195FC

Short answers for comparing this configuration before quotation.

Send your requirements
How do I select the engine size?

Send the driven machine, required shaft power, operating speed and duty cycle. Selection uses the rated output at the required speed, together with the shaft and mounting requirements.

How do the power take-off options differ?

Crankshaft take-off runs at engine speed; camshaft take-off runs at half engine speed. Specify the required shaft speed and connection.

Can I choose the starting system?

Recoil and electric start options are available. Specify your preferred starting system in the inquiry.
