Looking at buying a older 48" walker. Machine has 2500 hours but has a lot of new parts. Its supposed to be about a 1995 model but unknown since it does not have the year on the plate (have to go by that the dealer told me) I think it's a 20hp engine, but that lacks decals telling the hp. Engine was replaced 1,000 hours ago, runs good. Other than a gear box on the deck leaking slightly, and possibly the one that runs the blower/deck may have a bad seal as well, the machine is VERY clean for it's age. Also has a new (as of about a year ago) 9.5 bu. box, new belts, new blower, totally new caster wheels and tires front and back, drive tires are 75%. Deck is not original as it's a flip up type, was told that the flip up was not available at that time. I'm unsure if the hydros have been replaced or not, but I'm sure going to inquire. They seem to work fine after I adjusted the tracking though there's some sort of hang-up that causes it to turn to the left when I pull the speed control to neutral. The problem... The deck dosn't cut at the heights it should The 3" setting is really about 2.5" and it also is almost 1/2" lower on one side than the other according to a tape measure on level concrete. What's strange is that I mowed several lawns with it today and it cut level and quite well. That's what confuses me... Can't see what's tweeked to make the deck sit so unlevel. Only other real problem with the machine is the SPEED. I guess the older models were slower than the ones today... I assume that there's a "speed-up kit" available for this machine? Any ideas? With as many new parts as there is on this machine it really is in pretty good shape overall other than a few things. I'm really in need of the machine since I bought my 61" G-Hopper I need something mid-size that dosn't damage thin turf so much in the smaller lawns. Definately need it before the leaves start falling, and used walkers are not that easy to find around here. Thanks all!
