    GENERAL DISCLAIMER - PLEASE READ! The following engines on this page have some similar specifications as your FERRIS IS600Z's engine.

Although any of these engines may not be exactly (100%) the same as for your FERRIS IS600Z's engine , we feel very confident and are doing our best from our many years of experience to show you the closest engines we have in stock that have some similar specifications as your original engine, such as crankshaft diameter and length and mounting bolt pattern that may work for your equipment. Your exact original engine may not be available because it may: be too old to be in production or discontinued due to some EPA regulations.

Our customers may had bought any of these engines from us and may had done some modifications to adapt to work with their equipment including, but not limited to: transferring the wire harnesses from their old engines to the new engines, tappering the mounting holes, drilling new mounting holes on mower's decks, cutting and welding mufflers, ...etc.

Although we spent a lot of time to prepare, review and compose this page, the information here may not be 100% accurate as we collected them from our experience and from our customers on the daily basis. You should replace your old engine with the same brand, type, and series, specifications to avoid major modifications. Please contact us first if you have any questions or want to confirm before purchasing. We are here to help!

Our engines on this page have the following similarities. Choose the engine HP and the displacement (cc) accordingly to fit your needs:
    1. Bolt pattern - The mounting hole pattern are the same.
    2. The dimmension.
    3. Muffler configuration is the same (you can reuse your old muffler)
    4. Although spent a lot of time to carefully study about your engine, prepare, review, and compose this page to believe that your engine crankshaft size is 1-1/8" diameter x 4-5/16" length, it is still your responsibility to measure your engine crankshaft to double check if it is the same.

Other minor things that you may have to do when you buy the long block to replace your engine including but not limited to: transfer your wire harness from your old engine to the new one if it is not the same (most of these have similar wire harness though), tap/thread the mounting holes (as most of brand new engines did not have the mounting holes threaded/tapped by the manufacturer) etc..

Your engine choke may be (double check): SEPARATE MANUAL CHOKE (Mower needs 2 control cables, 1 for choke and 1 for throttle)

If after checking your engine/mower choke and the above is correct, your 1st option is to buy a SEPARATE MANUAL CHOKE engine or 2nd option READY START engine.

If the 1st or 2nd engine option is not available here, you can buy a CHOKE/THROTTLE COMBINED engine here and you may be able to connect your mower's throttle cable to the engine's control to do both choke and throttle. After connecting your mower throttle control cable to the engine's CHOKE/THROTTLE COMBINED control, the engine will be choked if you push the mower throttle control lever all the way up before starting the engine. After the engine started you will pull the throttle control lever down a little bit to get to full throttle or at the any level for your desired engine speed.

 BRIGGS AND STRATTON TWIN Cylinder COMMERCIAL SERIES 1-1/8" x 4-5/16".

As always, if in doubt or the information here is not correct, please contact us FIRST. Your current engine on your mower may looks similar to one of the Reference Pictures below.

If you believe more or less Horse Power (HP) CC or Gross Torque than your current engine will be fine with your mower, you can buy any of the engine in this box. Please choose HP, CC, and Gross Torque and engine choke style accordingly.
