I have a 2005 SLT1554, I bought it in brand new sept 2005. This tractor is ok. if you are mowing 3 acres on flat ground , not to hilly.
I have a 54 inch deck. I currently have 832 hours on the machine. The rear end, transmission, the gears inside are well worn. The bull gear with the miter gear in them with that small shaft has worn out and messed up the main bull gear. Anyone can get parts for this tractor SLT1554 through partstree.com. almost total price for parts that are worn is $ 160.00. On the transmission the oil that it takes is 20w50. Can this oil be any manufactor ?
The engine still runs great. I change the oil ever 25-30 hours.
The mower deck, I go through spindles like crazy. I did bend a spindle, I went and got another spindle, well the spindle that i got brand new from dealer was bent. The dealer order 2 more spindles. they come in and they were bent. I was like what the heck. Finally the dealer got some new spindles that was not bent. Well after 4 spindles. I finally got a decent one.
Also on the SLT 1554 it is best to get some good angle iron and redo the hitch area. The metal there is way to flimsy. If anyone uses this tractor in winter time make sure you can get ag tires or tire chains with some weight. This machine is pathetic in the winter if you don't have this.
I am going to make a phone call to HYDRO-GEAR to get more info on the hydrostaic drive that came with my tractor.
