Tiller questions for B7100

[M_Brown]

Got a couple of questions on Tiller for my B7100. I have access to a 48" tiller a buddy will loan me. Is this to much for my Tractor. I have 4wd with an HST tranny so I have 13 hp at the PTO,Rocky soil and some sod. The other question is what do I need to protect my PTO if the tiller comes to a sudden stop. Like if I lock it up on something like rocks, roots,ect. My manual says I have a one-way clutch cam to prohibit reverse drive when rear PTO speed exceeds the engine speed, but I don't think that would help if the tiller suddenly locked on something. Do I just need a slip clutch? and if so what is a good one to get? Mike

If the tiller is too large you can always remove a set of tines.

Can't help on make of slip clutch but would suggest you check out your local implement dealer to see what they have available.

I've used my neighbors tiller ~4' behind my B7100 HST in hard rocky soil to till over an acre. As long as I went slow enough the machine worked well, when I tried to go to fast the tiller wouldn't stay down but I rarly ran out of power (and I'm running at ~7000 ft). As long as you plan to go slow I think it will be sufficient. As for hitting rocks and what not I hit plenty of rocks from 1" gravel all the way up to bolders the majority were softball to football size rocks. The tiller I used had a slip cluch that prevented any damage to the tractor, I would suspect your tiller has a slip clutch or at the very least a shear pin. If it is a shear pin make sure the pin the the proper grade bolt and that you have plenty of extra pins. The clutch should slip or the pin should break before the tractor is damaged. Also, using other attachments I've killed the engine from full throttle when the mower hit something and stopped suddenly, and a similar event with a post hole digger. One advantage of only having 13 hp is that the engine dies before anything breaks. (at least thats my experince so far, knock on wood).

I have a gear drive B7100 and use a Landpride 48" tiller. I do not have rocky/hard ground and it works great. I usually till in low/1st or low/2nd depending. Works much better with moisture in the ground. Big rocks (say bit smaller than softball sized) usually just cause it to chatter and bang a bit before it spits them out. Mine has a shear bolt and I have never sheared it.

I went with the 48" as it covers both rear wheel tracks. My garden is 48" wide raised beds which have no sides, I just drive right down them and till them under. Have to do a little cleanup with what the tiller throws to the sides but it sure beats the walk behind tiller

Hey! Thanks guys for the response. The tiller has a shear pin. My buddy says it is a grade 2 bolt. Not sure if that is what should be in there. Sounds like I will be ok using the tiller. Thanks again. Mike

Another thing you can do is partly overlap the passes if the tractor hasn't enough power.

Yes, a grade 2 bolt as a shear pin is what you want. I used a 40" tiller all the time behind my B7100, but as has been mentioned, I think a 48" would work if you go slow enough. The other thing for you to consider is the driveshaft length. I don't know what tractor your buddy is using, so the driveshaft length may be OK for your B7100, but when I bought my tiller, I had to cut the driveshaft down because it was too long.
