mtd not pulling

Hello I have a lowes riding mower 90 model made by mtd.
The problem i am having with it is if you are riding on level ground its fine.
If you start up hill it will suddenly stop.In 3rd & 4th gear it does pretty good.But if you put it in 5th or 6th it will stop on a hill.I have put new factory
belts on it about 2 months ago and did the proper speed control adjustments
in the owners manual.The mower runs great and does fine except for this problem.I would be very grateful for any help on this problem.The only other thing i could think of would be the transmission.Thanks in advance the

Hello mowerman!

The fact that the mower moves in any speed tells me the tranny is ok. There are no different gears for speeds in the tranny. The different speeds come from a change of drive ratio determined by the position of the variadrive pulley. To me, it sounds like the middle section of the variadrive pulley is stuck. Remove the center plate where the gear selector is, and using a snap ring remover, remove the snap ring holding the variadrive pulley on. It is the pulley with both belts on it. Remove the pulley. The center sheave of the pulley should slide up and down, and spin freely independent of the top and bottom sheaves. If not, spray it with penetrating oil and work with it until it is free.

Hello cheese
Thanks very much for the suggestion on the pulley.
I will be checking on that in the next few days.
I am trying to get better on working on riding mowers.
Thanks again
