I noticed the season before last that my mower deck would slow down - yet the motor would maintain it's RPM's. Last season I didn't notice any problems with my mower deck or my rototiller. I actually used the tiller to work up my in laws rather rocky property before reseeding everything, due to the new electric and gas they had ran into their house. Even with such hard and rocky ground the rototiller never slipped - instead it'd shove the tractor ahead letting you know that the tines were not happy with the hard object they just encountered below the surface. Then, this season I noticed the mower deck started to bog down on occasion again.. and when I went to use the rototiller... it didn't seems to have the RPM or torque it did last year. My only conclusion is the PTO belt. Again, the mower deck isn't to bad... but the rototiller would occassionally stop while churning the ground (which I plowed and disked with my Brinly set).
Any thoughts? Which belts should I buy and where can I find the best deal?
I attached a picture of the dirt after using the disk - and one after/during tilling - with my garden helpers lol.
