Id like to know exactly what part broke on your engine. A few of the Personal Pace drives didnt work right last year either. This same basic Briggs engine is on Turfco aerators....? Its also on my Lawn Solutions aerator. As of yet nobody has given a comparison between the TurfMaster and Time Master power wise or an any other front....?.....? Honestly if my TimeMaster 30 died Id probably by another ASAP. Its notably lighter than the commercial version and the Personal Pace makes it ridiculously easy to use except on up and down hills. On those types of lawns that are small and/or forced to bag... I grab my yBravo 25. For the record I use Castrol 0w-30 which is a true SL rated oil not the weak sister SN & SM newer spec oils with less ZDDP. Since the Time Master races up to max rpm immediately just makes sense. I just cant see spending $1700+ on a commercial mower that cant bag grass in the rain like my yBravo 25 can. I can mow and bag wet damp grass with the higher lift commercial blades to a point on the Time Master but nothing like the yBravo 25. Still..... unless the cut quality is somehow better on the commercial model...no thanks. The shear speed of my Dually BOP mowers and flat manicured cut quality blows away both the Time Master 30 and the yBravo. Again for my use and purposes I dont see the TurfMaster as being worth the extra $. Both the Time Master and yBravo 25 are niche mowers. I refuse to use 21's.
