toro

I need a drive belt for an old toro...... jack"s recommends 5/8 x 901/2...tracter supply has 5/8 x 90........can i go short a half in????......or can someone recommend another seller........Jack is OUT OF STOCK.......and I have not bought from anywhere else....... thanks for any ideas......

I have a Toro MyRide 54 zero turm mower and the left transmission gets noisy and weak after mowing for 30 minutes or so. I can't find a dipstick, fill plug, or filter on this model. Does anyone know how to check the fluid or have had a similar issue?
