Difference 1057, 856, 857 other than engine?

[FLtractor 62]

Evening, other than the engine size, are there any differences between a 856, 857 and 1057? Are any of them considered more rare useful or valuable as a work horse mower? Easier to maintain or desirable features?

All those are basically the same tractor as my 68 Commando 8, nothing rare about them. Just model changes yearly.

Basically decals. Or possibly seat change design wheel horse golden era. Because these are four speeds, I would not consider them rare. But that timeframe if you had a six speed that would be somewhat rare because of the production numbers I hope this helps.

The mid 60s model numbers break down:

Ex: 856

8 HP

5 = THREE speed

6 ≈ 1966

 

Transmissions: 

4 or 5 = THREE speed

6 = SIX speed 

7 ≈ hydro

The six speeds are a special tractor because of the Limited Slip Differential. 

 

IMHO the SIX speeds with the Limited Slip Differential are the best of the mid to late 60s workers.

Maintenance would be about equal across any model. 

 

Desirable features might be a certain correct steering wheel or the cigar lighter. 

Certain implements too.

Best thing about the short timers. Turning radius. Great for mowing. I can buzz around and trim around my trees with my 875 and RD deck whilst my C-160 I have to futz around the trees to get it all. They are also great for plowing snow.

Thanks Garry. I forgot about the long frame on the 1057.

I’ll chip in that the LSD has more internal metal-to-metal friction than the 8-pinion or older bevel gear differentials whenever the real wheels are turning at different speeds. For that reason, it runs with a higher oil level than the earlier 3-speeds and I keep a closer eye on the transaxle oil and change it every other year (I estimate 30-ish hours of runtime per year). I’ll be putting in a magnetic drain plug at the next oil change, as well.

Generally, any stuff suspended in the oil as it circulates can become an abrasive and cause unwanted wear. Metal in particular. 

Transaxles have lots of metal rubbing against metal which can create metal particles through ordinary use. The design of the 5060/5071 LSD differentials has even more metal on metal friction. (This is not a criticism--I chose to take on the potential wear to get the benefits.)

While all the hydros and some engines in WHs have oil filters, most do not (my 854 with its 5060 and K181, for example). The magnetic plug can attract and hold metal particles and prevent them from circulating between oil changes.

Don Just saying I believe in diesel fuel or kerosene flush. I had a 606 one time of of EBay bid I could not move this. Tranny was frozen. Many flushes it freed up. Changed all sealers and sold it in the spring.

Different steps for different objectives. 

If I don’t detect water, rust, or other contamination, I drain and refill without flushing. In that case, any residual gear oil isn’t worth fighting over. 

The plug is for extra insurance. 

(Also, I don’t have an easy way to properly discard used diesel or kerosene so I avoid creating any when possible!)
