Does anyone know if the gearbox setup/config is any different for the 560 series?
I haven't disassembled the gearbox (Or any Victa gearbox to that point), but when I called Victa and asked for official workshop documentation that I could potentially purchase (For either the MSP562/MSV562/MMX482), they reported that essentially the official Victa manual is the Gregorys 424 manual (Which is no longer in production, but which I do own, and in it is reported that many of the images are provided by Victa, so it would appear they've worked collaboratively to produce this publication). The problem is the 424 manual stops at the 550 series and was last modified in 1991 (I believe). So if there was a change to the gearbox setup/functionality, I'm not aware of any official documentation of it, and as far as I'm aware at this point, Victa considers the gearbox/axle assembly a whole unit replacement which they don't intend to be serviced.
So I don't think we'll get any info on internal movements and how to troubleshoot. I think the closest we'll get is troubleshooting the pinion gears on the end of the driveshaft and the overrun clutch. Perhaps for more information, we would need to contact Victa directly and ask them... for this iteration of the gearbox (If it's different to the aforementioned 550 diagrams in the Gregorys manual), how is it supposed to function in relation to moving back and forth, and is locking up of the wheels normal, etc.
I did expect that it would be more difficult at least to a degree to move due to some sort of engagement by the gearbox, and I can deal with the slightly more difficult movement, my main concern is the wheels locking up because if you're doing something as simple as moving in a square, whenever you get to a corner and need to rotate, you can find yourself trying to pull the mower back when the wheels don't want it to move and as everyone has mentioned and it is true... it's not a light unit without pulling it against its' will! An alternative is to lift the rear of the mower and pull it back towards you with the freely moving front wheels, but that should never be recommended or considered a safe option in my opinion.
Thank you all so much for your replies and for looking into this. Unfortunately I haven't had a chance to take another look at my mower and see what's going on, but as soon as I do I'll post an update, but of course, feel free to continue troubleshooting and if there's anything I can help with I will. If you'd like pictures of some pages from the 424 manual to assist, please let me know, I'm more than happy to provide them.
