What size finish mower for my size tractor?

new2diesel · Jul 10, 2013

I am wondering what the largest finish deck I can pull behind my 20HP 2cyl. diesel? I was thinking 60". Is 72" too big for this size tractor? Thanks in advance for your responses.

My first tractor was a 21 hp 3 cyl diesel and the dealer set me up with a 48" mower. The same tractor will pull a 54" mid mount mower no troubles. Sixty inches may strain it a bit if you don't have low gearing.

This is what HP Woods recommends for their rear mowers:

I think you'll be fine with a 60"mower.

60 inch should be fine. 72 would probably be a little much.

I have easily pulled a 5' REAR DISCHARGE finish mower with a FORD 1210 (16hp, 13hp PTO). My new to me Mahindra 2015 gear (20hp, 18hp PTO) man handles the same mower.

You wil be fine at 60".

If you are just mowing grass it doesn't take a lot of HP for a mower. When you start getting into the 72" or plus size mowers the weight of the mower should be taken into consideration. My 30HP Kubota is only rated for a 500 pound rear mower. My 72" mower weighs 719 pounds. Although my Kubota powers this 72" rear mower easily I am pushing things quite a bit with this much weight on the three point.

I have a 24hp (at the engine) yanmar 2cyl. I can run a 72" mower on it but its all it wants. Now if you cut your grass weekly you could prolly get buy with a 72"er but for me its weeks often months and i have to drop a gear and take 5ft bites to keep the mower speed up.

I dont think they put a limit on what the yanmar can lift on the back like that. They give your lifting limits like were your releife will pop on the three point but i dont recall seeing anywere to keep a weight to a certain amount. Maybe cause its old and a grey model? But if it can lift it the tractor should be able to handle it or else they would set the releife lower you would think.
