Off hand, ours has these features which the TB does not: Adjustable detent valve, coil protected pressure hoses with NPT fittings (opposed to hose clamps), horizontal shaft Kohler engine with .95 gallon fuel tank vs Honda with .3 gallon and vertical shaft for longer run time, full beam construction, fully boxed tongue with a flip down stand vs U channel and pin, manual canister, in-tank suction screen and return line filtration, larger coupler L090 vs L075 for increased durability, larger pump 13 GPM vs 11 GPM for faster cycle time, built in log cradle which will last forever, ability to add a 4 way wedge and log table. Lastly it looks cool and you will have the satisfaction of helping a little employee owned company grow as opposed to putting money in the pockets of a big conglomerate. Those are some of the reasons, maybe not all of them.....oh and we sponsor this forum!!
Cheers and good luck either way!!
