New Kohler Aegis Torque Monsters...

[TLS]

Look here...

With the LH-750 and LH-760 (27 & 29 HP) coming in with mid to high 40's in the ft/lb department, they are now the top dog in the 2 cylinder gas engined torque race!

I just stumbled on their site today. Maybe this is old news, but here it is
anyway.

The only problem with those engines is they are only horizontal shaft. This is a good thing for Exmark but a lot of the other manufactures use a verticle shaft engine.

the verticals are still high at 32.8 and 38.5.....

these are some nice engines, they have certainly come a long way over the years!

Anyone think next year's Exmark line might bring an Aegis powerplant to the table?

I reall dont consider those two figures "high". Run of the mill 25hp A/C Kohlers are 40 lb/ft, and they are by no means considered a powerhouse.


Keith,

I don't know for sure if Exmark is going to offer this engine. They did let out a little secret a while back in their fourm about future powerplants. They didn't say what the secret was....but said there were changes in the mix coming soon. They have a lot of time invested with the Kawi LC design, and now with Kawi offering their LC'ds with EFI, the power race continues. Who benefits?....US!

More POWER ! :D

The new 28 hp EFI vertical shaft comes in at 44 lbs/ft of torque. That's not too shabby........Lynn

Does anyone know how they stack up against the GENERAC or the new KAWASAKI efi?

MONTE,

If you lean them real carefully, you can "STACK" them as high as you want! :D

The 29hp DFI L/C Kawi looks to be quite an engine. I like Kawi's website, they show HP & TQ curves on a graph! Not just peaks like Kohler does. The new Kawi 29hp has a VERY flat torque curve, where my 27hp tapers off at the top end where WE need it most! This is the big advantage of EFI/DFI. It gets as much juice as it needs! Not too little, not too much!

The GENERAC is Aircooled, and a 50-75 cc bigger engine. So I would hope it would feel slightly stronger.

TLS Thank You for the reply! I tried out a 27hp l/c kawasaki last tuesday and I was impressed with how quite and strong it is! The 29hp efi must just be awesome!

Looks like a bolt-in swap from a Kohler 25.


Just think of the difference going from a tired old Kohler 25 to a crisp new Kohler 27 for the vertical shaft ZTR repowering.

I don't know why it's taking these small engine manufacturers so long to improve their engines. Honda went from air to water on the ATC250R in 1984 and along with some other improveents like suspension, it was like night and day. Maybe it's the cost. I know they have the technology. Same thing with Yamaha. Yamaha is such a strong manufacturer with so many different engines on so many platforms, why aren't they represented? There are also European manufacturers to consider. I think the current crop of EFI and water cooled engines are just the tip of the technology iceburg. Things are only going to get better with time. I wish I could put my old CZ400 engine on a mower, GOBS of torque!

[Keith]

Speaking of the Kohler 27, that will be one of Exmarks new engines...well the horizontal version :) I can only think the 28 EFI will be one of the other two for 2003.

The Kohlers have respectful torque "ratings" for small displacement v-twins (725 cc). The Generac Guardian GT990 used by Dixie Chopper (Vertical Crankshaft) has 30HP @ 3600 and 54 ft.-lbs. @ 2600 rpm. Horizontal Models are as high as 55.7 ft.-lbs. Size does matter Generac 993cc.

does anyone know the torque numbers on the kubota 28hp,3cil diesel???
