@ Arkie Jim:
I've got a Woods RM48 finish mower, a Woods RB5 back blade and a cultivator. A previous owner added a 40# or so steel counterweight on the nose. Ag tires on the rear. So far with the implements I have the weight is enough to not cause the nose to lift up. I had a Yanmar YM1700 briefly with a 6' mower that would lift the front right off the ground so I know how important weight can be!
I replaced a few of the pins and clevis rods and got a new top link from TSC because the previous owner was trying to run some kind of mishmash of Cat 0 and Cat 1 parts on the three point so I got everything all Cat 1 now.
Fuel bowl (I thought) was clouded over and no longer transparent... until I unscrewed it and found it was packed full of dirt! Luckily the Fuel and Oil filters are a common type that was in stock by Purolator at my local Advance Auto Parts. Gave it a good greasing, changed the oil with 15W40 Shell Rotella T, flushed fuel system, new fuel filter and blew out the air filter. She runs like a top with 752 original hours as of today.
Cut two acres with it today, graded half a mile of gravel driveway last week. I'm quite satisfied with my Buck. Got a grand total so far of about $2000 invested in everything which for the market today seems quite a good price.
