This oldy is new to me. It came without a carb. If anybody may know, If I put a carb on it from a 10 hp Kohler, which has the correct linkage and mount, will it lean out and hurt it or just less powerful than the correct carb ? Also if you please, does anyone know what exactly goes into the hydrostatic trans/diff/fluid pump? I believe it is all one unit as far as the fluid goes. I have read about ATF type F, Regular hydraulic fluid and dextron II but am not sure. The unit has a filter and I would like to put in fresh fluid and a filter before I test start it. More questions to come. Thanks for any help you may offer. Please excuse the repost as I seem to have started in the big tractor forum instead of garden tractor as I should have. Bill

I use type FA ATF in the hydro on my MF12, and they both use sundstrand transmissions, so I would think that would be fine, and they are all one unit. As far as the carb goes, I think it should be fine, just less powerful, just make sure you set it right, but then again I usually work on tecumseh's and not Kholers. Good luck.:goodl:

I go with either Dexron III or if using for heavy work...Shell Rotella 15w40.
You can get by with that carb. May be slightly down on HP due to throat size, but should adjust to run with proper mixture. Will hold you over till you find correct carb, or may do just fine depending on how you use tractor.

I'm running Heavy Duty 15-40w, seems to work great for lifting, pulling, digging, and scraping, with all the implements I use on my MF14

It does deliver higher pressures, especially on worn units. Plus holds pressure better at higher op temps.

RE: hydro fluid
Sooo nice to hear back from you guys. I am confused though. If on one hand you can use dextron III and for heavier duty use then use 15w40 then I am confounded how atf vs engine oil is even in the same ball park of comparison. I do hope to to use the tractor for heavy use as it has a loader and I will soon have tons of DG/sand to move. I wonder if the hydrostatic trans will hold up vs the clutch type tractors as I have no experience with these hydro's. I have not even driven this thing yet. Am hoping to find a used scraper box as this has a real nice 3pt hitch in the rear and I have nothing yet to take advantage of this great feature plus PTO. TKS Bill

Bill, WELCOME to MTF.

The type of fluid you use in your hydro depends on operating conditions (air temp), condition of equipment (number of hours) and availability, as long as it is a "quality hydraulic fluid" (Sundstrand's words). Here in a temperate climate (-30 to +90 F) I have used Dexron for 27 years and over 2000 hours of HEAVY use on my MF1655, which is your tractor with a two cylinder Onan engine.

Heavy uses I have put my tractor to include;
Spreading and levelling four 17 cu.yd. loads of sinter on my driveway (over 1 ton / cu.yd.)
Excavating 55' of my 24' wide driveway to a depth of 3'.
Filling that hole with gravel and levelling it.
Removing 18" of garden soil from an area half the size of a regulation sized volleyball court and refilling the resultant hole with 8" of crushed gravel.
Many other smaller excavations and fillings.

ALL with a 54" wide x 22" height and depth bucket and no transmission issues.

These are all secondary jobs! The primary job was snow removal for up to 8 neighbourhood driveways for snowfalls from 2" to 12" normal and once (thank the Deity of your choice it was only once) 60". Average snowfall of 60-80" for 24 years = how many tons from about 800' of driveways. THAT is HEAVY WORK.

I think your tranny can hold up and it won't burn up any clutches.

The 3pt hitch has a lift capacity of about 350 lbs.

Sorry for the long post.

I've used regular tractor hytran fluid in my 1650 since I've had it. Same fluid in my 1450 & 1855. The 1650 and 1655 are different tractors, not just single verses twin cylinder but most use the Sundstrand hydro, my 1650 has the Eaton hydro while the 1450 & 1855 have the Sundstrand hydro's.

I didn't know that the 1650 was different from the 1655/1855. I had always thought those 3 were basically the same and the 1200/1400/1450 were shorter. Is there anything else different besides engine, transmission and length?

Thanks for the info.

My 1650 has Sundstrand hydro as does my 1655, but some 1650 do use the Eaton unit. ALL through 1855 use the same differential, but the 55 series use 6 lug hubs/rims instead of 5. Also, the 1450-1650 drives from the engine straight to the hydro, then belts up to the rear pto shaft. On the 55 series, the engine connects to the rear pto shaft & belts down to the hydro unit. Also, the 55 series does not use a mule drive up front. They have twin belts down to a jack-shaft, which you connect a pto shaft to the deck, or to the front end of shaft to power snowblowers & such.

Thanks olcowhand. I forgot about the wheels and I've been looking hard for them since mine are rotted out. Found a set on eBay that I hope will work. Not too many 6 hole 12" rims around, and even fewer 3 hole 8" rims for the front. Just bought a pair of Cushman rims on eBay that I hope will fill the bill on the front.

[butchs_hobby]

I'm pretty sure the frt rims on the 1655-1855 tractors are the same as the rear rims on the MF7&8 tractors. The 1655-1855 tractors are physically bigger than the 1200-1450-1650 tractors.

Do you know of anyone who rebuilds the old MF 12 hydro trans?

 

[Dean1956]

I would myself be concerned about running too lean with that sized difference of a carb. If it were 2 hp difference or even 4 is one thing but a carb for 10hp is definantly jetted smaller than a 16hp even though the draw through would be greater. I sure would do a little more checking first. You could always check you exhaust temp for a lean or rich running engine, just my 2 cents

didn't the old Yazoo front mowers had 3 bolt hole rims (8") that fit the Masseys?
