Default Bolens 1256 hydrostatic questions

Brought home a 1256 -07 Bolens Husky yesterday and I adjusted the carb and the Wisconsin engine started right up. I had the option between a 6 speed and the hydrostatic but I chose the hydrostatic cause I would be mowing, snowblowing, and tilling with it. Was it a bad idea to go with the hydrostatic? Are they good and durable transmissions?

My other questions is, is that it doesn't have much power going slow. It will slowly move along then when it hits resistance it stops and makes noise like something is slipping. The belts and drive shaft are not slipping from what I can see. Is this normal? Are there seals that wear out and can be repaired? or do I have to fork over another pile of money for a replacement transmission?

You made a good choice. Have you checked the hydro fluid in the tank under the seat pan? There is a cap right in front of the seat. Make sure also that you have the throttle wide open. The hydro system has full charge at full throttle. Lastly, make sure and change the hydro filter.

Those hydro's are bulletproof. The 1256 uses an eaton model 10. As long as the fluid level is maintained and you don't overheat it, it will last forever.

Be sure and clean the fins on the hydro unit (where the driveshaft goes). They get caked with dirt and oil and this can lead to overheating. Also make sure that you still have a driveshaft fan.

Thanks for the replies. Hydro fluid looked good. I didn't have the throttle all the way up cause it was late and that thing is LOUD. I can try to get pictures tomorrow but I am leaving for a few weeks starting tomorrow. My brother may be on my account here to ask a few questions cause he is gonna be working in it. I wish I am gonna be tinkering on it as well. The hydro still has the cooling fan and the fins don't look clogged up.

I managed to get the hydro filter off by jamming a screwdriver through it cause nothing else would work. I think I'll slowly turn the hydro to flush the old fluid out while the filter is off. The fluid didn't look bad but I'd thought I'd do it anyway. What filter do I use as a replacement? Will any filter work?

Is there are place to get replacement brake pads?

Can't wait to get this thing running. I sure like the thought of hydraulics. I am having second thoughts about leaving the tractor other behind.

Hopefully I'll get you guys some pictures before I leave.

NAPA has a filter that will work.

Don't let your brother have all the fun. Great little machine that will give you lots of hard work.

Only rear problem the tractor seems to have other than very worn steering spindles.
Any tricks for the loose and worn steering spindles? The one wheel turns about 6 inches before the other one moves.

I do have the attachment parts for the tiller but not the lift rod to the hydraulics.

Those pictures look great. The tractor overall looks to be in really nice condition. See just where the play is on the spindles. Sometimes it is just a worn spring pin. Mine was very sloppy and I replaced the pin that goes through and it tightened it up pretty good for only a buck. I am working on an eaton10 right now. I'll post some pictures of the internals for your viewing pleasure. They are certainly well built.

It is definitely the steering spindle that is worn the hole through the spindle is rather oval shaped. I compared the diameter of the spindle bolt to the one in the parts diagram it appears that the PO already drilled it out bigger. It looks like i'll have to buy some replacements.

Is that a crack in the pto just below the top bolt hole? or a shadow?

Steering spindle being worn out is a testiment to that particular tractor's reliability. The 1256 is considered by most to be the best tube frame Bolens built. That one has obviously had some hours put on it. Not to worry, it looks like it has plenty left to give. Keep your ear to the ground, someone in your neck of the woods will see you on it and start talking about others they have seen or own that are parts tractors. Keep an eye out for any H-14's or h-16's. They have techumseh engines on them and the engine usually wears out long before the tractor ( I'm going to catch some grief for that statement from the tech owners, sorry). They front ends on the tube frames were all the same. If you can't wait that long, put an inch of weld on the spindle where it meets up with steering arm. Make it easy to undo, should you ever need to take it apart.

[QUOTE=ratboy;1763922]Is that a crack in the pto just below the top bolt hole? or a shadow?

Yes that is a crack. I haven't had time to really think about it because my full attention has currently been on the hydro.

I drained the fluid in the hydro, which BTW takes forever, and changed the filter.
When I tried to refill it, it would only take 1 quart. I have heard that it should need about 4 quarts. I read in the manual that there could be an air pocket so I tried what they recommended: running the tractor on idle while pumping the travel pedal back and forth. Is the tractor supposed to move while doing this? Mine didn't. I only tried this for a short time for fear of ruining the transmission.
Do you have to do this for awhile before the fluid level will go down?
Is there a better methods for getting air pockets out?

Emailed sambolens asking about steering spindles. He responded today saying he has them for $65 each which seems like allot to me. Maybe i'm just to stingy. Not sure what I will do. Since someone already drilled the spindles bigger then if I replace them I will need to also replace the piece that the tie rod attaches to.
