B6200 has sluggish power

[ABuddy]

Just acquired a B6200. It had been sitting for 6-7 years uncovered.

It started up ok, but didn't have any power and only worked in low gear. I drained the hydraulic fluid and cleaned /replaced the 3 filters per the service manual. The fluid drained out water for the first couple of cup fulls from both lower drain plugs. The two cleanable screen filters were very dirty as well. Installed new replaceable filter. The tractor is now running in all gears but still very sluggish. No transmission pieces visible but there were some shaveings

Should I try to flush and clean/replace filters once again? A friend has loaned me a compression tester to see if engine is in good condition. I will also remove the gas tank and do a thorough cleaning.

Has anyone had any experience with lack of power on a hydrostatic tractor like this?

Thanks for any input.

I would recommend replacing your fuel filter(s) and air filter to see if this makes a difference.

After doing the above recommendations work for a number of hours several of which should be hard. Keep in mind the radiator whistle and check it often.

Thanks for the recommendations.

My son replaced the fuel filter and air filter.

What is the whistle on the radiator? I would like ot try to work the tractor but it barely drives as it is. Very little power... I drove it for about twenty minutes. no better power- maybe less power at the end.

Son is going to remove the fuel tank and completely clean out.

Fresh fuel should help quite a bit. Diesel fuel doesn't store well without a fuel conditioner in it and, 6-7 year old fuel even if it had conditioner in it won't be in very good shape.
Fuel that old could plug a new filter almost immediately so you might still need a new filter after getting rid of the old fuel and adding fresh.
If your B6200 is like mine was it will have no temperature gauge, the way you can tell if it is getting too hot is steam issuing from under the hood. Mine never got that hot so can't say if it whistled or not but that would be a good indication that it is too hot.

The Radiator overflow valve has a whistle on the end of it.

When sitting and the clutch not engaged how does the motor react?

Are the brakes free or do they bind?

Have you check linkage on throttle cable?
Check any rubber hoses for air leaks.
Not sure if your model has knob/lever flow hyd. to rear/front..maybe knob/lever needs adjusting.

Update:

Completely flushed and cleaned the fuel tank and replaced with new fuel filter. And Mystery Oil -Bulldog

Worked the tractor as best we could given there are no attachments as yet. Son (200 lbs) held onto roll bar and skidded behind. Unit would pull him on level ground but only in lowest gear. Higher gears he can stop it. But hey, this is a tremendous improvement from when it first arrived!!! WIll probably drive it again today and then drain and replace/clean filters.

Thomas- hoses and linkages appear OK.

Egon- motor is same when clutch not engaged, and brakes are free. Ran motor hard per your recommendations. Seems better. Will flush out again and clean replace filters.

thavil- did filters.

Brandero- Fuel was a mess. Completely cleaned out tank and put in another new fuek filter. Engine is not smoking anymore!

Here's a picture of my new prized 6200.

Also a picture of a someone else's 6100 tractor with hydraulic ram. My dream is to attempt something like this in order to attach a front bucket for the boys. Does anyone have any idea of costs involved with adding hydraulics for a future FEL? I have a wire feed welder and grinder etc.

Many thanks again Gentlemen.
