Let me correct my previous statement a bit.... Viscosity comparison between ISO numbers and SAE numbers are difficult. ISO viscosities are at 40°C (104°F) while SAE number are at -18°C (0°F). This said they are not apples to apples, but ISO 46 and SAE 10W-30 are going to be quite similar in...

Keep in mind that ISO 46 is only effectively “thicker” than 10W-30 at low temperatures. At operating temps 10W-30 will act like 30W and therefore actually be thicker than ISO 46. See the link below to a chart that may help demonstrate this. I would still recommend checking the control linkage...

Torque is one of the factors of HP, so this should be reasonably in line given you are operating about the same speed as the mower is designed for. Given how a mower is usually used the perception of torque will probably be more influenced by the rotating mass you have (flywheel effect) than by...

OK. Sounds like you have this under control. Good Luck!

One more thought... No matter what you do, I'd advise to closely watch your temperatures when you are running this so you don't fry your machine. Watch both the engine coolant temperature and the hyd oil temperature (at the cooler exit). Either one may be your limiting factor depending on...

Sounds like an interesting option. If the mower was set up for a 540 rpm pto, then I guess you'll be spinning it about 20% faster than intended, but that might not work too bad.... I guess you could run at 80% throttle if nothing else although this will take away some of your HP available...

That sure doesn't sound like a fun issue.... Did the head gasket you replaced show any signs of crossover between cylinders or into a water jacket? If no, I would be suspicious of a crack in the block and/or a badly installed liner (not sure if you can get liners for these engines...). I...

There are a lot of variables to consider here.. Like if there is a gear box on the mower and all the points Ken made above. Generally speaking, mowing any kind of heavy brush or grass sucks a lot of horsepower. Theoretically you could cut it with about any combination imaginable if you went...

Note that squeling when turning and low flow (I assume you mean at the aux hydraulic couplers) are two separate issues if nothing else. These are control by two seperate pumps. Piston pumps for drive (1 for each side) and a gear pump for the working hydraulics. Are you sure 9 GPM is low? See...

I agree with Tazza that you are best off sticking with the recommended oil and that changing it probably won't fix your issue. I am not sure I totally agree with the statement that the hydrostats will always make noises when moving. I agree this is common if the neutral adjustment is out, but...

Sorry that I am just seeing your post now. Here's some info on the Volvo SSL's - The original design came from Scattrak (Omniquip) and was bought by Volvo in 2002. The first Volvo machines were produced in 2003 and the most significant updated occurred in early 2006 (B-Series). If your...

Thanks for the feedback. I am clear on which relay is the interlock relay. My dad replaced this so I don't know the details, but I know he replaced all three of the relays in the panel. And yes, the interlock one was not cheap, but he was able to dig it up on line somewhere for $9. He said...

I found that there is a rather general wiring diagram (would not call it a schematic) in the operator's manual. Between this and some probing I was able to figure out somewhat the how the service/run switch works. I was getting some weird resistance readings on a couple terminals (based on...

Thanks Ken. I fixed my settings, so hopefully my formatting works better. I took a look at the manual per your link. It seems the wiring diagram section is missing though. Pages 55-16, 55-17, and 55-18 seem to be were it should be, but these pages are blank when I view it... It might be...

I have found lots of similar posts on here to my problem, but have not been able to resolve the issue. I have seen reference to a thread called "LX665 Won't Start", but can't seem to find this exact thread for some reason. Here are the details. - LX565 ~1994 - Intermittently will not crank when...
