Pick the post. We'll name the driver and the sleeve you actually need, so nothing shows up missing a part. The post RediDriver is a gas powered post driver. It runs on a Honda four stroke engine, needs no hose and no compressor, and drives posts from ground level. One person carries it from post to post. No. A RediDriver is fully self-contained. There is no hose, no compressor and no power cord, which is the entire reason the tool exists. The MEGAmulti. It hits 30 joules at 1780 impacts per minute from a 2 HP Honda GX50 engine. The REDIboss78 and REDIclassic52 hit 26 joules from a 1.6 HP Honda GX35. The MEGAmulti also has a larger piston, heavier internals and a longer duty cycle. Wooden posts, steel posts, T-posts, U-channel, sign posts, guide posts, fiberglass rods, grounding rods, rebar stakes and tent stakes. Post size picks the model: the REDIclassic52 handles items under 2 inch, the REDIboss78 and MEGAmulti handle up to 3 inch OD, and the REDImagnum105 guide tube takes the REDIboss78 to 4 inch. Yes. The MEGAmulti's exclusive multi adapter guide tube takes all Postmaster types, 3 inch round and some square profiles without changing an anvil. It is the only RediDriver built for Postmaster posts. 26 joules on the REDIclassic52 and REDIboss78, and 30 joules on the MEGAmulti. Impact rate is 1720 BPM, 1740 BPM and 1780 BPM respectively. The MEGAmulti hits harder (30 joules to 26), has the bigger engine (Honda GX50, 2 HP, to the GX35, 1.6 HP) and takes Postmaster types and some square profiles on its multi adapter. The REDIboss78 is 4 lbs lighter (35 lbs to 39) and takes the widest range of sleeves and adapters, including T-posts with the T-post sleeve. Both carry the same 3 year warranty. Buy for post diameter. Under 2 inch: REDIclassic52. Up to 3 inch with the widest adapter range: REDIboss78. Postmaster types, square profiles and the longest duty cycle: MEGAmulti. Commercial and DOT crews driving U-channel and guide posts: the Commercial / DOT package. If you drive 3 inch round posts, Postmaster or square posts, or a lot of posts in a day, yes: it hits about 15% harder than the REDIboss78 and is built for a longer duty cycle. For T-posts and posts under 2 inch, the REDIboss78 or REDIclassic52 does the job for less. Only if the post is narrower than the guide tube. A sleeve keeps the post centred so it drives straight. Rods and rebar always need one, a 13/16 inch sleeve, on every model. No. The MEGAmultiguidetube, MEGAcrankhousing and MEGAcylinderliner are exclusive to the MEGAmulti and are not compatible with any other model. Going the other way, the four REDIboss78 reducer sleeves (1 3/4", 13/16", 2 1/2" and 2 1/4") also fit the MEGAmulti. For every other part, the compatibility matrix shows exactly which drivers it fits. No. REDIboss78 sleeves are cut for the 3 1/8 inch guide tube. The REDIclassic52 has a 2 inch guide tube and takes its own sleeves, such as the REDIslvrod52poly for rods rather than the REDIslvrod78poly. Straight unleaded gas, no mixing. Engine oil is 10W-30 and driver lubrication is EP 0 low viscosity grease. Use only EP 0, do not substitute. Clean it after each use to remove dirt and debris, and lubricate regularly.
