Countax B60-4WD Loss of Forward Power

[David Catlett]

Hello,
I am hoping that you might be able to help with with diagnosing what might be wrong with the transmission on my 2018 Countax B60-4WD mower. I am experiencing a loss of power that gets worse as the system gets up to normal operating temperature. I have noticed that this is only really affecting forward motion. If I try to approach an incline, the mower struggles, however, I can reverse up any incline without any impact on performance. I have checked oil levels and I have checked the neutral position. I have also inspected the oil and it is in good condition. I am assuming that if I had air in the system, I would not get the performance that I currently do in reverse. I am concerned that while the obvious thing appears to be to purchase a repair kit and replace the motor and pump, I can’t help but think that these elements must be in good condition to get the performance in reverse. Are you able to confirm my thought processes and advise on the best course of action?
Many thanks,
David

I only have one hydrostatic device (Allen Mayfield 8), but I have found it is VERY touchy about correct adjustment of the F-R lever. Get it a bit wrong & it'll push a house down in F, but barely move uphill at all ( & vice versa). So I'd have a good look at the motion lever linkages for wear/adjustment before taking any drastic steps.

I know you said it goes ok in reverse but check the drive belt isn't loose or covered in oil first.
