657 vs 857 vs 1057? differences, engine suggestions?

[thejangler 5]

Few questions, I have a 1967 wheel horse 657 and would like a little more power for plowing and such

 

Is the only difference between 657 and 857 and 1057 engine size? frame the same? could i find a bigger engine to put in it without fitment issues? suggestions?

thejangler    as for the 657 frame I believe you can put in a 8hp kholer in it Good power there. Not to sure about a 10 or a 12.  I think if you go larger you run into different belts and pulleys. Not much difference between the 6 and 8. The 8`s you can do a lot with them. I have an 8 hp do plowing with it Have a 10c.u. dump cart I fill it with dirt- rocks -wood -tow up hill with it. the thing I like it is a small frame get in to tight spaces with it. Enjoy it what ever you decide.

     I am not as well versed as some other members when it comes the the subtle differences between long and short frame  in 1967, but I think the 657 and 857 were both short frames and the 1057 and 1257 were long frames. I have attached the manuals for you to look at and hope you can find what you need there.  

 

 

 

            Also, you may want to read this over and adjust your plow angle.

I have an 857 and have a 10hp Kohler out of a 1054 sitting on the shelf. I too am wondering if that motor will fit under the hood without modifications. Looking forward to hearing from those of you who have done this swap.

Good info from both Richard and Gary. I don't think a 10+ Kohler will fit under the hood of the short frame 657 or 857. Maybe a Tecky will but I don't know. I'm with Steve and would like to hear if anybody has tried to fit the bigger block in a short wheelbase. I'm thinking a no-go without cobbling the hood.

This post shows an 875 that was fitted with a 12hp Kohler.

Big block shortframe square hoods rule ...I think @squonk would agree .

Glad to see another member from MO. I like the 8hp kohler big enough to get the job done but still small enough to make it interesting. 

[Racinbob 11,419]

Interesting. I thought those were long frames. I see the 875 and 1075 use different belt guards to compensate for the difference in shaft height. Unlike the 70's b/c series where the 8hp sat on a riser plate making the shaft the same height as the bigger blocks. Interesting stuff. OK, who's got a 16hp mounted on a short frame?

What is the lever protruding from the belt guard? Only thing I can think of is the hydro release so you can push it. Couldn't find it in the schematic though. Thanks.

Up to '66 , most hydro models had that lower lever to engage the hydro belt drive and parking brake setup . It all changed in '67 to the lever mounted on the right side at the top of the trans tunnel .

I believe to install a 10 hp you'll need a engine with the short oil pan and the correct belt guard which are specific to the 10 hp short frame tractors

I have both a 1067 and a commando 8 (which is 1 year newer than the 857 but the same machine) The frame is deffinatly longer on the 1067 and the hood is longer and taller. A kohler 10hp is massive compared to an 8hp. I think It would take an extensive amount of modification to fit a 10hp in a 857.

AWESOME, that is really helpful to have the comparison here.  seems like a really big difference in the 8hp and 10hp like you said, thanks again,  merry xmas yall!!
